I offer my prayers to the gods of the SHO in the hopes that they might take pity on my plight and offer advice
Heres the story. I acquired a 93 auto SHO basketcase through a trade. The car was running the day before, with a misfire, that i attributed to needing a tuneup and valvecover seals (plug tubes were totally filled with oil.)
I DID NOT check for spark presence at this time, i assumed it was there. (oops). Replaced the gaskets, plugs and wires. I don't think they had ever been changed, most of the plugs that came out had been worn open all the way to 0.080!
I put everything back together and cranked it up. Wouldnt start. I jumped the fuel pump from the test terminal and pressure was good, checked spark and had none. Thinking I must have left a connector unplugged i pulled the intake again and checked everything out. 99% sure I didn't miss any plugs or hook anything up wrong. I did find one unconnected pig tail in the rear lpassenger side of the bay, near the EEC-IV and ABS test plugs. I don't think it is supposed to be plugged into anything, but im not positive. Ill take a picture if anyone suspects this.
Did the KOEO test and got the following codes:
116- Coolant temp sensor out of self test range
636- trans fluid temp higher or lower than expected
542- fuel pump circuit open; PCM to motor.
No idea if those were present before i did the valve cover gaskets. From the combination it seems to me like a loose connector or ground, but its been a while since i worked on much EEC-IV.
Can anyone offer some advice on what to do next? Ill be searching old topics but i figured id get it asked so maybe someone can see it and advise. Thanks.
