Very Ill 92 Need some major help

[darylP]

A few months ago my wife decided to let my son drive my 92 to learn how to drive a stick. My 92 has been running fine untill that day when they backed out of the driveway and it died never to start again. Sofar I know I have no spark or fuel injecting. Yet I do have fuel pressure at the fuelrail. I have tried a new crank position sensor and cam sensor with no luck. Have checked all knowen fuses and the two fuseale links I know of. Plus have checked timing on elt and chains plus checked key on crank snot. I'm lost for the firstime on this car. Don't know what happened. Need some ideas. got a scanner but nothing new there. Please give me some ideas. also have replaced the dis module and coil pack before the car died. tks Daryl

what is it doing while cranking?

 

[darylP]

Just turns over does not start.

 

[SASHO91]

have you checked compression?
have you checked the timming belt?

 

[darylP]

Yes have checked compression and checked the timing all is fine. Just got no spark or fuel being injected..Maybe the relay to feeds the pcm and coils? If so which wire should I check to see if theres volts?

 

[SASHO91]

sounds like the IRCM.

im not sure on what wires to check...

but i do know that if you want to check your fuel pump, you can do so with the EEC connector... IIRC its on the bottom, and second to last pin. Ground that with a jup wire with the car on. It would help if you had a FP guage on the rail too...

 

[darylP]

Well I know the fuel pump is running got good 38-40 psi at the fuelrail. Just nothing also works.. Need to find out how to check the IRCM to see if I got power leaving it for the coils and injectors. I know the pcm is powered up sence I hooked up my scanner to check for codes and it was alive.. Is there different feeds for the coils, Injectors and PCM?

Can you pull codes from the car? If so, I bet that will tell you your problem.

If you were a bit closer, I would take a look in person. You could also check out the local NW club at www.nwshoc.org and post up your problem to get more local help.

Good to hear from you.

Yes can pull codes but all I get is codes for the items not currently connected like TPS and Maf. Nothing else out of the ordinary. Can someone please tell me if the PCM, Injectors, DIS (coils) share a powerfeed or does it come off different lines. And which wires feed them from the IRCM?

 

[darylP]

FYI Here are current codes KOEO 122,551, Memory 111. KOEO codes due to those sensors being unplug with intake removed...
