Hello,

I recently got my 69 out of storage...been sitting for a couple years. Before I put it down there were no issues. Started it up and drove it for about a month last summer. When it died on my twice while driving. Now when I start it in the garage it will run fine. The radiator dumps and will continue to run several minutes. First test it stalled while in park. Second test a day later it stalled when I put it in gear. I tried starting again and I seemed to want to start, but then lost all spark again. It seems to happen only when the engine is good and hot. I can hear the injectors clicking. Fuel pressure is fine during/right after the stall. Trying to start again, there is no spark...like something is telling the ignition to turn off.

A little info on the car:
- TPI fuel injection installed on an otherwise typical pre-87 350
- Accel computer, closed-loop setup (Gen 6, if any one else uses this ECU)
- Computer controller HEI from a 90's Corvette
- Already replaced the ignition module, didn't help
- Accel super coil on HEI distributor

I've plugged into the ECU and all the sensors (MAP, O2, Air Temp, Water Temp) all seem to be reading correctly.

Possible issues(?):
- Idle Air Control motor (how can I test this?)
- Coil?
- Anything else in the distributor worth looking at? I've bought a pick-up and condensor/resistor thing....not sure what it's called. It's just such a pain to pull the distributor.
- Neutral safety switch faulty? (This should only prevent the starter from turning, not shut down the ignition right?)
- Running 0W synthetic oil for some reason....i don't think this would affect oil pressure. The gauge reads fine. I don't think the oil press. gauge is even tied into the Accel ECU.

Any thoughts would be extremely helpful...Thanks!!!
