I just talked the guy who is putting my engine in and theres a problem. Normally, when you turn the key to the accesory position, the fuel pump goes on for 2 seconds then shuts off, then after you start it, it turns back on. Well, the problem is, the fuel pump doesnt turn back on after you start the car. I used to have a 4-way chip with security mode, and he thinks that could be the problem. He said maybe it did something to the computer when i took it out. He checked the intertia switch and thats not the problem. Any ideas. I have to call him back in about an hour.


thanks

 

Unplug the computer from the system to reset it. Let it sit for 10 minutes or so that then put it back with no chip.

 

theres hasnt been a chip in the truck for 7 months and there hasnt been any power going to the computer for about the same time. do you still think that would help?

 

did he check the computer for codes, maybe the computer stored a code when your motor let go?

 

I hope he plugged in the computer harness.

 

i dont think so, ill tell him to if he can

Flying ****
they did

 

should have read the post better, sorry. Good luck guy, hate to see you run into a bump in the road after this load wait. It will all be worth it though. Hang in there.

 

Your oil pressure switch seems to have gone bad. A little birdie told me.

im not really sure what that is, but he said he was getting good oil pressure when the engine was running. the engine will start, but turn off seconds later. could the switch still be the problem even if im getting oil pressure?

 

For the first 2 seconds the pump runs is to prime and start the truck then the computer allows the pump to run only if the oil pressure is good, and if you have a bad sensor, it wont let it run.

This sounds like a bad chip connection, but there is no chip in the truck right? Just have him clean the PCM, maybe there is some build up on it shorting it out?? Didnt a friend of your put something on the PCM to try to make it look factory? Clean that crap off.....

 

If it was a bad connection to begin with that the truck wouldn't start.

I remember one of his friends adding some homemade goop to the contacts that "LOOKED" factory, no telling what it may be doing....

 

Oh, O.K. Guess we'll have to see if he managed to clean all that crap off, then.

FYI, my "friend" who put the stuff on the contacts was a ford tech for many years and deals specifically with lightnings. He was not just one of my school friends who said they know what they were doing. And, the stuff that he put on the contacts is the same stuff that ford uses....

I overnighted them my chip. Even though sal doesnt think it has to do with the chip, there is no harm in trying it. If thats not it, I will have them check the oil pressure switch. They said that that they are almost sure that is not the problem but well see...

any other ideas?
