Several days ago, I was leaving work to run home and grab my cell phone I had forgotten. As I turned out of the parking lot and onto the road, I gave the car some gas, and was shifting into third and it started spitting and sputtering, and died. I assumed I had ran the car out of gas, as I had never pushed the gas hand that far before. Ended up pushing the car into a parking lot, put some gas in it, and it still wouldn't start. Hours later, my brother and I went back and started messing with it. Found the fuse for the fuel pump to be blown.


Bought a new fuse, put it in, car fired right up immediately, excellent! Drove ~2 miles home, and the car died as I pulled into the driveway. The fuse blew again.


After a little research, it seems it would be caused by a faulty ground, or possibly a CCRM problem. This was an all of the sudden thing when it happened, I've owned the car 5 years almost and have never messed with the fuel pump so I don't se the ground being the problem.


What could it be? Trying to eliminate simple stuff before jerking the CCRM out and dropping $150 when it doesn't fix the issue.

first incase you did not know DO NOT PUT A LARGER FUSE IN IT PLACE!!!

2nd - with electrical problems the kiss-theory is the best method and you need to start with the simple/easy checks before you start replacing things hoping it will fix it. Trace the power wires back from the pump and make sure that there are not any spots with wire showing through the insulation and shorting out.

You might also want to check the injector harness, particularly under the intake. I have seen a few cars melt the wires because they were touching the intake and arching.

the kiss-theory

Keep it simple, stupid...

I love it!


Also, Incase it comes down to it. I have a spare CCRM sitting in my toolbox at work. I could part with it for fairly short money!

how old is the pump and the fuel filter? if the pump is old and worn the draw could be getting too high which will pop the fuse. put a clamp meter on the fuel pump wiring and see whats going on. also if the filter is clogged the same thing can happen.
