In your June 6th post,( no crank) you stated you had the EVTM & the service manual. You should be tell from looking in them which wires are energized when in crank mode & that the ECM does need a crank signal as well, which you have eliminated.May be part of your current issue?Sorry it took me long to update. Thanks: KMT,DOUG H, 35th the plug behind the battery was plugged in, I cleaned it anyhow and checked all grounds. Perversely I cut out out the W/PK wire from the neutral switch and ran a new one up to the solenoid for a no crank problem (that worked).
This last week I've jumped some wires from ICM to PCM. Car fires up from the key, but only runs a sec. or 2 them dies, it's got good fuel psi.
Long story short.... I'm trying to get it to run before I hookup the plumbing from the blower incase I needed to go back in deeper. Question, (Could motor be getting to much air without blower plumbing hooked up & dyeing and or from cutting out and rerouting the W/PK from neutral switch but not rewiring in the GY/R like on page 24-4 and 24-5 of the EVTM causing the die? Also is this GY/R wire only hot when in the start position?
Any help is greatly appreciated. (Good thing I'm retired LOL so I've got time to work on this Black beautiful / black leather 93 SC. I'll get it running, it's getting closer till the next problem pops up)
