94 GT Cranks, no start

[stanger9410]

He hooked his computer into the OBDII port under the dash, i did not know it was a dead plug, he seemed to have gotten information out of it, i watched it read the car and come up a 1994 ford mustang gt with a 5.0L 302. im going to check the injectors and still see if a different computer does the trick. hoping for the best with that. at least it is winter time and i dont have to drive the car everyday!

That is not possible. The OBDII under the dash is not connected to anything on a OBDI system which the 94-95 5L's are. There is absolutely nothing that will read as you stated above from the cars ECU. What you saw appears to be his input to let the scanner know what it's searching for. FWIW you are being taken for a ride IMHO. PM me about getting the FORD service manual, EVTM (Electrical and Vacuum Troubleshooting Manuals), Service Manual and PCED (Powertrain Control/Emissions Diagnostics Manuals) on a CD.

Okay so where im at now. i pulled the codes. at first i was getting the 11 code first saying computer okay. now im getting 511 twice in a row then 112, and 327. im not sure if they are 100% correct. i know the 511 is, i will have my code reader in today so i will know for sure. 511 is saved memory test fail? what does this mean??

511 either means your computer is toast (unlikely) or that you have a chip plugged into the diagnostic port on the computer. Do you have an aftermarket chip installed? If so, you can ignore the 511 code.

Here's a great resource for all your trouble codes:

Okay thanks, will keep this updated...

So im getting code 10 also, i dont see it on any list of codes? anyone have an idea?

 

[stanger9410]

OK Ive made some progress. the car runs now, the gear at the bottom of the distributor had sheared the pin that held it in place, thus not spinning the rotor in the distributor. so now it starts and still runs like it is missing. it doesnt want to rev up, im getting code 511 with the chip in and 512 with it out. i have a manual that said 511 requires me to replace PCM. any thoughts?

 

[toyman]

Is that the only error code? Perhaps something in the PCM is fried.

 

[stanger9410]

it throws code 511 or 512 first (depending on if the chip is in or not) then code 10, which my manual says is a separator code that separates the constant memory code from error codes, then code 111 which is system pass, so i didnt think that was one to worry about....

 

[stanger9410]

I called Brenspeed today to get their take on it. they said that 511 meant the idle air relay or valve (i cant remember what they said) has gone bad, hoping this is the issue, seems like an easy fix...

so i got the car running correctly, had to buy a new ecu, took a few minutes for it to learn it but seems to be running good now! thanks everyone for your help!
