SHO wont start

[HELLBENT93]

Well my SHO wont start and I really dont know for sure what could be wrong. On a short drive home from school today the car started right up fine and drove all the way to my house about 3 miles. I shut the car off and went inside and was planning on leaving within a couple of minutes to go get something to eat...but no i turn the key and nothing. All my accessories work so its not any kind of power issue. It cant be the fuel pump or the relay cause I just replaced them. I am kind of suspecting a leaking water pump/cps thing. Is it possible if the cps has enough time to dry out that it will start working again or does it go bad and stay bad. Could it be the starter? Just a thought. Anyone have any other ideas? Thanks for any help

When my cps went it started after a little while. But the car tried to turn over but just didnt start!

The crankshaft position sensor will not prevent the starter from turning the engine. It will only prevent it from starting. Your problem is in the power supply to the starter: battery, battery terminals, cables, ignition switch, starter solenoid or starter. You will have to troubleshoot some more to determine which. Just because your lights light up doesn't mean there is enough current available to turn the starter. Checj the battery voltage with the headlights off and then on. If the voltage drops below 12 volts with the lights on, the battery is weak.

Checked the voltage and its fine I think i've narrowed it down to the solenoid took almost two hrs to get the unit out i might just replace the whole unit to be on the safe side. we'll see what happens

Do your battery cables get warm to the touch if you try and start it for a few seconds? (don't hold the key forward too long) If so, check the connection on the starter, check your ground straps/cables (battery to block, block to body, and even that battery to body one)
Have you ever noticed if it seems to crank slower when it's warm?
If it's only doing it when it's warm, there's a good chance that it's the starter on it's way out. When it's warmed up or heat soaked, then it'll start to show up the flaws of weak windings or brushes, and it'll draw really heavy.
I don't recomend this, but this is what I'd do in that situation. when it doesn't start, I'd take some old peice of crap screwdriver that you don't care about, cause it's most likely going to loose a little chunk out of it, or some kinda jumper wire, and cross the terminals on the solenoid. But really, don't try this!

That's just my way of eliminating the solinoid as a problem.

so in closing, I hate electrical problems

And since it's almost 6am, i totally missed your last post. So if you've got the starter out, some auto parts stores, or just a decent garage will bench test the starter for you, tell you if it's good or not. Should be free, call around.

If your deal is a crank and no start you might consider checking in the high power fuse box under the hood for a blown 30 amp fuse for the ECM or a 10 amp fuse for the ignition coils....to coin a phrase from Fred, just a brain puke, good luck

thanks guys. i pulled the starter/solenoid out and had autozone bench test it and it was the solenoid, i replaced the whole unit just to be safe. my sho is now back on the road, thanks for your help!

Ford has been using the same solenoids for years and it's very uncommon from what I understand for them to go bad. But I guess if they never went bad then autoparts stores wouldn't carry them.

Glad to hear that your SHO is back up and running again. I know how frustrating it is to not know exactly what's wrong.

I was just thinking something here related to the starters in the SHO's.
Mine's a 92 so I've got that small gear reduction starter with the solenoid build onto it right? and the 89-91's have that huge old clunker starter with the separate solenoid on the side of the inner fender? Let me know what you've got, cause if i remember correctly, 92 was when Ford came out with that newer gear reduction starter, cause it took much less power to turn and it spun faster and it was much smaller and lighter.
I just remembered someone saying that it's a job getting the starter out of the gen I's and is that why? Cause it's a lot bigger starter?

yeah thats right the 92 was the first year for the starter/solenoid unit and thats what i have on my 93 so yours is the same. i dont know anything about the starter and solenoid be harder to remove on genI, i do know that it is damn near impossible to get to the upper mounting bolt for the starter...many, many extentions

 

[SHO 3.0]

I just know that in my SHO it's easy to get the starter out, but I've heard from some that getting it out of a gen I is a pain in the ... butt
I'm just realizing/remembering it now that they've got the bigger old starter.

Mine took a couple universals, but I got it out fine during my clutch job.
