3800 Help ASAP, car died

[imported_Diavolo]

Car was fine all day. It started to stall a lot but that happens when my vacuum line comes off my MAP sensor. So I was goign to to fix that problem when I get home (happens once a week and usually isn't a problem) Well, then my ABS light came on and the steering felt very tight.

I made it about a mile when my car stalled on me again, I went to start it up and it idled for about 3 seconds and died again. This happens every time now, the car will idle for a few seconds then die.

anyone know what problem this could be? My cell phone is almost dead so when I get home (at a friends right now) I will get it plugged in and give you my number if you need more details or whatever.

Thanks
Mike

and I did connect the vacuum tube to the MAP sensor

Check the entire vaccum line that runs down under the SC into the intake manifold, and also check to see if the line is connected everywhere else. Maybe just a vaccum leak.

Could it also be the alternator?? I know beckys truck did that a few times then just stopped starting completly. That might not be it, but it could be something to consider too. Just trying to throw things out.

possibly the fuel pump resistor again?? Everyojne else seems to be ahving the same problem.

the whole vacuum line is connected, what is the fix for the fuel pump resistor?

 

[rob]

Did your SES light go off? If not go to the fuel pump resister. They are a very commen fault. Ive heard of guys jumping them out-be careful if you do-use a fused jumper to check it. Replace it if its bad-its there for a reason.

I havn't been able to scan my car because my palm pilot ran out of batteries and when I replaced them I lost my LS1M program. sigh, where is the fuel pump resistor? I also got my phone with me now, number is 513-461-9289. If you need details or whatever, thanks

Using that page I am going to try this. but I don't really understand it, bending the lead into the relay?

 

[blitzu]

Your symptoms sound very consistant with a MAP sensor that isnt working properly... see if the wiring to it is all in tact. When I did my GT swap I had to have a wire extension made for the MAP sensor and the car waa having all types of issues just because the power to the map sensor wasnt at full because of a bad connection.

Check the connector going into it and the wires, unplug it and plug it back in. Might help.

Problem fixed, It was the fuel pump resistor. I want to thank you guys for the input, also Wayne from CNCGP who called me up and let me know about bending pin 86.

thanks

Make sure you R&R the resiter. Pump has two speeds to regulate fuel pressure on SC vin(1) engines. The resister is normal pump speed. The PCM controls it via pump speed control relay. Leave it jumped out will cause the pump to be running high speed at all times increasing your pressure that may lead to premature pump failure or other problems down the road.

 

[imported_Diavolo]

I just ordered the fuel pump resistor kit form pfyc. I probably won't even drive it until I replace the resistor. Thansk for the forewarning though.

 

[sweetness]

i think caspers has a product that bypasses the resistor, and increase WOT voltage to be sure you are getting everything out of the pump that you can.

maybe, maybe not.

I"ve been runnning mine bypassed since 2001. So far so good..... Of course now that I said that it will die any minute now! :huh:

 

[alexgtp]

Hmm I have also been running mine bypassed for the pat 1.5 yrs..
Maybe that why I am running so pig rich..?
