This is on my Thunderbird, but I figure there are plenty of knowledgeable folks here who might have some insight.
The MS unit in question is an old V2.2 MSnSE set-up I built for my TBird probably 15 years ago. I recently had the car off the road for a while doing a bunch of work. I recently got everything back together and restarted and pulled the car out of the garage yesterday.
I'd fired everything up a couple weeks ago and let the car run for a bit, but wasn't ready to get it out of the garage until this weekend.
I fire the car up and tweak with a few warm-up settings and then get it out of the garage. The toddler and I go for a quick putter around the block as an easy shakedown run (New custom rear suspension, rebuilt diff, etc, listening for noises). We get back, I shut the car down and prep to leave for a longer drive.
Car fires up and runs fine for the 6-mile drive. No weirdness, and nothing looks amiss on the laptop.
Get back. Park the car in the drive to give it a quick bath. Shortly afterwards, I go to start it, and I don't hear the FP prime. Hit it again, no prime. Try and start it a few times, it cranks, but doesn't fire. The pump is kinda noisy, so it's no mystery when it's running.
After a few tries, I give up and we (dejectedly) push it back into the garage. While doing so, I remember that I probably didn't snug down the db37 connector when I stuck the ECU back in the car. I go and correct that, but still no luck.
I did a little poking around and here's a couple things I found.
- The "Injector" LED on the case is flashing, even when the ECU is off. Dim flashing. LED goes full solid when key in "RUN" position.
- The ECU stays connected to the laptop (In Tuner Studio), even when the key is "OFF" and the ECU is supposedly "off" (It'll cycle connection when trying to start the car)
- The car has one of the MS Relay Boards in it. The Main Relay switches when the key is turned to "RUN" and I hear the FP relay click, but no prime. The relay for the FP is good and sees power.
- At the Relay Board, the injector fuses are seeing between 3-8V with the key in "OFF".
- I was just checking things a little bit ago, and when I turn the key to "RUN", my Odyssey battery is making a high-pitched sound.
Trying to figure out what the hell happened in the time it took me to wash the car. The car was running perfectly fine right before that.
Any thoughts?
