I just read the other threads on this and I am having some problems figuring out what the problem is with my car.
I went to the drag strip the other day and my first launch my car hooked pretty good but then just died. There was no drama, it just lost power and rolled to a stop. I had to have the car towed home as it would crank but not start. I do not have any wiring diagrams so please be specific.
The car was running fine and I even autocrossed it several times with no problem. Here are the important details followed by my questions:
1. The car is turbocharged and had a bigger fuel pump installed.
2. The inertial switch was "disabled" by Monkeywrench racing when they did the fuel pump and other work. It looks as if the inside was taken out as it will not trip no matter what. (I did however previously discover it was left dangling and was dragging on the axle so the rubber cover and a little plastic on the outside is ground off. I had moved it about a week prior to the event)
3. The fuses all have power and are all good.
4. I have a fuel pressure gauge and it does not have any pressure at all.
5. One time it blew a fuel pump fuse (at least that is what Monkeywrench told me it was and it acted the same way) They replaced it at the time with a larger one and it started right up.
6. The fuel gauge was not working correctly once before after I got it back from Monkeywrench. They found a loose ground? (No problems since then)
7. Along with the fuel gauge, the speedometer also every once in a great while will not work. I then shut it off and restart it and it will work.
8. Once after washing it in a spray off car wash the car would not start but cranked. (at that time I am not sure if it had fuel pressure). This was after having it back for a week following problems #5 and #6. I took it back to Monkeywrench for them to diagnose. It started at their shop after being trailered there and they were not really sure why.
9. My door locks and alarm were not working right prior to all of this. I could not get my car to lock/ unlock on a regular basis. (Just prior to this happening I did accidentally lock and unlock the doors which was not normal)
OK, so at this point I am guessing that it is either the fuel pump relay or the fuel pump itself (but the pump only has about 1500 miles on it). We checked the wires and there do not appear to be any bad connections.
My Questions I need help answering:
1)Where is the fuel pump relay located? Can I check it?
2)What color wires are the power wires for the fuel pump? I want to check the pump itself but could not figure out which wires power it.
3)What are your thoughts on the inertia switch being "disabled"?
4)Do you think the door locks or alarm have anything to do with this?
5)Am I on the right track and is there something else I should be checking?
Thank you for all of your help. I need to get my car running again.
