Hey guys,
I have a 90 hatch with a redtop sr that was running perfectly until the other night. While on the freeway my car just died, the lights didn’t dim or die and everything electrical inside the car still works. Once pulled over the car would still crank over fine but it wouldn’t fire. I get it towed home and realize I’ve lost fuel, spark, and my e-fans.
The pump won’t prime. I’ve also noticed the ecu led does not come on at any point when I attempt to start the car. I’ve searched all over but no one seems to have this exact issue, its more people who have just done their swap and have never had it run.
A few things:
- This happened right after I drove through a very small puddle, and this was also the first day I had driven it the rain.
- Checked all wiring for melted spots and found nothing.
- Pulled the ecu to check for burn marks from a short, looked fine.
- Checked all grounds, everything looks good.
The fact that I lost fuel and spark at the same time makes me think its not something trivial like a fuel pump relay or the ignition amp. I know a bad CAS can cause no fuel or spark, but would it just die like that out of nowhere?
Anybody have any ideas? I know I have some multimetering to do but if you could point me towards some other possible causes for all of these issues that would be greatly appreciated.
