car died while driving...stranded...fuel delivery issue please help
Ok so basically I bought 18psi's old car from Ed and started driving back from utah to texas. The car worked flawlessly till I reached the texas state line and then rpms, acceleration just stopped and gas pedal was unresponsive. Some passerbys stopped and discovered the fuel inj 30A fuse was blown. We put in the head 40A fuse and that blew as soon as trying to start the car. They then hooked up a volt meter or something and had me turn the car again and it started smoking where their wires were placed. They said I have a short somewhere thats not letting fuel get to the engine. The car tries to turn...battery and engine seem fine and all fluids are at good levels so it seems it has to be related to the fuel delivery system. Im writing this as I wait for a tow truck as I have no tools anyway and am still 6 hours from my home city of san antonio. Please chime in on what this could be. If ots a short...where is it likely to be found? Fuel pump dead? Fuel pump relay issue? Injectors even? I also dont know enough about megasquirt but could that be a cause even though nothing was adjusted...didnt even hook up a computer to it. Cars breaking down is nothing new to me, but being stranded sucks so all help is appreciated!!!

Does that car have a diypnp? Or some other form of standalone megasquirt? Trace the injector wiring and go all the way into the ms. Something has to be making contact or grounding out that shouldn't be.

There was just too much stuff about this car I wanted to change or add for my personal taste, and I don't have the time or money to do it and selling it put us in a better financial situation until I can get a solid job. I would have wanted to: put quicker spooling turbo, quieter exhaust, fix paint, add rollbar, full retune, change suspension, and at least a couple other things. But I lived and learned and now I'm more prepared for when I'm ready to choose my next car.

Sorry for the late reply...its been a busy couple of days. Made it home late last night and pretty much passed out all day. Turns out a wire came loose from the megasquirt behind the dash and was the culprit. Attached the wire back up, replaced the fuses, and let it run for 30 min just to make sure it wouldnt burn out again. Finally got back on the road around 4pm friday. Definitely an easy fix just a very inconvenient place and time for it to happen. About halfway between Carlsbad, NM and Pecos, TX on a highway with just 1 lane each direction and nothing but open land inbetween. It worked out I guess...allowed me to rest for another night after the tow (almost completely covered with my insurance) and to miss a huge storm that I would have run right into. Down side was the amount of time it took to find the wire...since I didn't even think to look inside until I spent a few hours in the engine bay. In the end, car still pulls hard and is a blast to drive. With some improvements, it will be even better! I'm happy with the purchase overall though and thanks to everyone who offered input. I found those wire diagrams very useful as well.

Thanks for posting the update! Glad to hear you got it sorted, and that your insurance covered you, and that you're happy with the purchase overall. Freak happenstance that it happened like that but hey, stuff happens.

Yea it was just an unfortunate circumstance that nobody could have predicted. I honestly blame the combination of poor bumpy road conditions throughout some of the drive plus the stiff suspension. I did enjoy a lot of the drive though too. Some very nice mountain views and the best part...passing slow 18 wheelers!!

If I were single there's no way I would have sold it. Haha! That's how it goes.
