Hi Guys -
1994 NAS D90 - pretty much stock and freshly rebuilt. By rebuilt, I mean almost totally rebuilt... 3.9L, R380, LT230, new galvanized frame, new dizzy, new ignition barrel, new ignition amplifier, new alternator, new starter, all nice clean grounds, repaint, all new suspension bushings, rebuilt front and rear axles... the list goes on and on. Got her back on the road a few weeks ago and drove about 1k miles since.
Last Saturday drove through a massive storm for about 1 1/2 hours. Water leaked in the front vents and windows/doors (no surprise). Made it home just fine and the next morning she fired right up and I drove for about 20-30 miles. No problem. A bit later, I went to get gas and after filling up I turned the key and the fuel pump didn't prime. I pushed her to a corner of the gas station and came back the next day with a new relay for the fuel pump (and one for the main relay as well). Fired right up
Drove around for a day and then she started running rough and the CEL came on. Threw a 45/44 code. I had replaced the O2 sensors about 3K miles ago and the exhaust system is new. As I was pulling into the garage to begin some further investigation, she died and won't start. Cranks just fine, fuel pump primes. I checked for spark and nothing at the coil. Checked battery voltage - 12.55V. Checked power to the + side of the coil and it reads .3V. Negative side is zero. Sounded to me like an ignition switch failure so I swapped in a new ignition switch and no change.
Main ignition fuse in the engine bay is good and there is battery power there. All fuses in the cabin fuse panel are good as well. I have started continuity checking of the ECU but thought someone might have a few ideas I could try. I have scoured the forum but can't seem to find a relevant thread.
Thanks in advance!
