1992 sho check engine light new to this car

[redteamgo2000]

ok so i just bought this car and it has a few trouble codes. they are as follows...
212 - IDM to PCM SPOUT signal loss circuit grounded.
217 - DIS coil 3 circuit malfunction.
542 - fuel pump secondary circuit open PCM/ fuel pump ground.

so my question is can someone tell me how to go about fixing this problem? i have never worked on one of these let alone own one so im at a complete loss as to what id going on and do not want to take it to a dealership. please any help is greatly appreciated.

well the 217 is the DIS module on the passenger side of the intake. That probably has to get replaced, they do go bad from time to time. It may be the coil as well so you might have to change bother. I have a few of each if you want Ill sell you a coil and dis just send me a pm if youre interested.

 

[redteamgo2000]

ok so now what?

i changed the coil pack and the ignition module and also new plugs because they were in sad shape. now the car wont even try and start but i have fuel and spark. can someone enlighten me as to what route to go because as i said before i have never worked on one of these and the dealership around here doesn't want to work on it. please help im way in the money hole and falling fast.

Are you certain that you have fuel and spark or are you assuming you do because you "replaced components?" Where are you testing for fuel and where for spark? At what points? I have some simple advice.....if your engine was running before and now after you did what you did it is not, your problem lies 99% in the work you did. Did you reconnect the electrical connector to the coil and ignition module. Have you checked to make sure they are properly connected? Does the engine sound odd when you crank it like the firing order is out of whack, thus, she can't spin over freely because when one cylinder fires, another on the up stroke is trying to fire, causing the starter to hang? OR, does the engine crank over and over sounding normal, just not firing up? Are you sure your plug wires are on right with the correctly timed firing order? I just did wires on my 3.2L ATX SHO the other week and tracing those things in the back of the stock locations can be tricky, I drew a diagram and did ONE at a time, but I got it right the first time. That engine is packed in there!! We need more information on your problem than you've supplied....."does not try to start."

 

[redteamgo2000]

firing order is correct i know im getting fuel and i know it's getting fire i checked it at the plug and i got spark. the plugs are wet with fuel but the engine wont start. double checked the plug wiring and it's all connected right but no start. cranks over fine just wont run.

Well, if what you say is all correct and you have everything you need, I am not sure why it is not running. All you need for a 4 stroke engine is a mechanically sound engine with the ability to intake fuel, compress it, ignite it and exhaust it. With those things, you will have a running engine. I still bet dollars to doughnuts you are missing an issue with the fuel or ignition. How long are you cranking it? Could it be flooded for some reason? Also, have you tried cranking it and spraying some wd-40 or other flammable starting fluid straight into the intake (disconnect the hose and shoot some in and then crank it). This will simulate fuel intake IF there is an issue with the fuel injection. If you are 500% sure you have fuel and ignition, I am not able to assist anymore without being in front of the car. I am fairly certain you don't have one of those or else you'd be running. Why don't you reinstall the original COIL and the ignition module one at a time and see if you have any luck? Even the wires if you have to. You're not running, there has to be a simple reason why and I bet you anything it has something to do with what you did because you were up and running before.

 

[cmeseadoin]

Perhaps you have spark but due to whatever reason with some component, you have way to weak spark. Make sure you have a good ignition module / coil and replace the new ones with the old ones and try that.

please don't listen to cmeseadoin. Do not spray anything into the intake.

Where did you get the spark plug wire sequence information? I know for a FACT that it is published incorrectly in several different books.

If you are getting fuel, spark and air, then you are not getting the spark at the right time.

Either you have some wires crossed or your timing belt skipped teeth.

ok now the car runs but it's over fueling bad ie. black smoke out exhaust and idle is about 2500 til it warms up then back close to factory, also smell gas in car. got rid of the codes from before but now have alot more. the codes are 113, 118, 121, 123, 528 and 542

 

[redteamgo2000]

sorry to be a pain but i really like this car and i just want to get it running good. im mechanically inclined i just dont know anything about this car and everywhere i look no one can tell me what causes what to happen. i found this site and you guys know your cars so im just trying to learn slowly mind you but im trying. thanks for the help i really really appreciate it.

I have done this procedure on everything from a chainsaw engine to lawn mowers to automobiles to diagnose potential fuel delivery issues. It hurts absolutely nothing. Afterall, starting fluid is MADE to inject in the intake of a gasoline engine and I've never blown anything up with WD-40 either. Anyone with ten brain cells would not dump a gallon in the intake, you simply atomize a quick spray in there. HOWEVER, I had already suggested he might be flooded due to the plugs being wet as he described it. In that case I would already have determined that I am probably flooded either due to constant cranking and fuel injection with NO fire, OR, something else is loading it up with gas incorrectly and I would probably NOT spray anything else into the intake seeing that. I suggested it for IF he should surmise a fuel delivery issue. WELL.... LOW and BEHOLD what did we find out??......

""ok now the car runs but it's over fueling bad ie. black smoke out exhaust and idle is about 2500 til it warms up then back close to factory, also smell gas in car. ""

FLOODED!

I post on many forums and I don't take what anyone says they know or what they have done to the car with any more than a grain of salt. Half the people on the forums are clueless (that is why they are here). Unless you are infront of the car you have NO idea what the **** is going on and so all you can do is make intelligent suggestions based on the facts presented. Everything you just suggested is a variance of what I already have except for the timing belt. Excellent suggestion, what are the odds that with him pulling off all the components that he did and re-doing the wires that the timing belt suddently jumped? There is a better than 95% chance that he did something in the process and if he has what he says he does....Fuel, compression, and ignition and everything working correctly, he'd be running. We all know that. SO, SOMEthing he did screwed something else up I guarantee it. No one can assist anymore, he'll have to figure it out by methodical diagnosis. I think I did a FANTASTIC job assisting this person, afterall, all 7 of my cars including my SHO are running just fine tonight. LOL!!! Humor me some more with your BS comments about not listening to me. I think he needs/wants to listen to me cuz his car ain't running worth sh&* tonight by the sound of it to me!

I appreciate the gratitude...my previous posting is not for you, rather geared towards some other genious trying to belittle what I suggested. I am not listening to that sh*& from anyone, esp. someone that comes to a thread that's been going on for the whole day back and forth and then suggests almost exactly what already has been suggested trying to portray themselves as the NEW resident genious. Fu*& that! Then they belittle the person prior by saying not to listen to them!! That is garbage. Why don't we have 93rev2sev explain WHY you should not listen rather than make some bullsh*& comment like that. If it were stated "that you probably don't need to spray anything in the intake now that we know the plugs are SOAKED, then I can understand.....but not to listen? LAUGHABLE!! I am all for helping each other out, but I DO know what I am talking about and will not have some SFB on here that I don't know from Adam belittling me. They can stick their head between their legs and fart for all I care.

Now, back to your problem......I am going to have to think on this some more honestly. Did you do anything under the hood where you have somehow tapped something loose or screwed up the fuel system....injectors disconnected or ANYthing like that? Have you checked ALL of your work and anything CLOSE to where you were working. That engine is packed in there, could you have worked something else loose, etc.? You're simply having TOO many other issues to have just replaced the coil, module and wires. I am thinking that something else was compromised......more to follow, I have to get up at 5am for work. Will be back to see what else is going on tommorrow!

try searching those engine codes in the search engine hereon the forum.
cmeseadoin: rev2 sev has a few more post than you so be careful.
does the car have a chip? if so try pulling it out.

That matter ZERO to me but thanks for the suggestion. What am I being careful of? Is he coming for me? LOL! I am sure I have a few more than he does elsewhere, so really, it matters not to me. ****, if they don't like the way I do things, they can ban me from the site. I am selfish and EASILY an a&*hole when I am pushed....so if someone doesn't like me, block me. That simple. I am as UN-politically correct as you will get. That is for stupid people with no backbone who have been brainwashed. As long as my stuff is all working, that is all I care about LOL!

ok so i know im getting to much fuel but what will cause the 542 fuel piump secondary circuit open? i think if i can figure that out my over fuel problem will go away. i have checked everything and when the cars idling that high it runs great and when the rpms drop back down it runs ok but there still is all these check engine light codes that i cant figure out why or where they came from because tues. they werent there. i only had a code for the coil and ignition module and now all these are showing up. as for the guys belittling you as i said before im here to learn and as also stated im clueless to this car as to why im here looking for help from the guys (and maybe girls.. not sure on that) that know them. i am glad you guys want to help me as no one else does, it's not their car so who cares right. but i really have looked over everything and as far as i can see it's all back to the way it was sanse the over fuel and all the new codes. im bout to pull my hair out as i've only had the car a week and am learning quickly that parts are pricey. i love this car and want to drive it. i cant afford the stealerships around here to look at it and tell me whats wrong or i'd be there first thing in the morning. im just glad i have a place like this for knowledge and help. you guys and or girls are the best.

 

[redteamgo2000]

so can anyone tell me what causes code 542? thats really the only thing i have let to do and the cars back to good again. please one last question about this guys.
