3800 Help, car died while cruising

[SaturdaysGS]

I was cruising along at about 25mph thru the neighborhood, the rpms started to go down and the engine stalled. I slipped it in neutral, started the car and it went to idle, then stalled again. I tried this 5 more times before I called it quits. :angry: Everytime the car starts, it runs for about ~3 seconds, then dies out. NO security light. NO check engine light, NO other warning lights. I tried keeping the revs up, holding them at about 3k, the engine still stalled while I was holding the gas. No matter how much I pushed the gas, it made no difference, the engine would stall out no matter.

I hooked up my handheld scanner to the car, and noticed everything showing readings MINUS the bank 1 sensor 1 (front) O2 sensor. The rear started to show readings (.015) before the car died, while the front showed .000.

Fuel pressure regulator dead? O2 sensor dead?

FWIW I have the fuel pump re-wire, and I do not believe its a fuel PUMP issue.

Help!

Also anyone in the area if they want can take a look at it with me, its a few blocks away from my house just sittin.

Oh yeah, I HATE THE RAIN.

did your fuel pump rewire retain the stock fuel pump speed relay?

Hmm.. I have no idea? I guess I could go and bend tab 85, and see if that helps. I do hear the fuel pump prime though.

 

[xierxior]

speed control relay keeps the pump going after the car is started

sounds like a fp resistor to me. a fpr wont stop it from starting, and an o2 would set an ses light

exactly, fuel pump resistor! same thing happend to me about 2 months ago.. exact same thing

The ZZP rewire keeps the resistor IIRC, I think only the Casper's kit bypasses it all.

yep - you got yourself a fuel pump resistor gremlin

sprinkle a little bit of magic fairy dust on that sucker and you'll be on your way




or you could buy another resistor and install it yourself, actually that might work the best

Definately was the fuel pump resistor. I used the pic from one of the guys sigs on ClubGP, but my fusebox was layed out differently. I went by the chart on the fusebox cover and found the FP speed control relay, and bent out the tab (tab 85) that was the same (the relay, not location though) in his pic.

Thanks guys, I thought the ZZP FP rewire bypassed it, but guess not. I made it to 128,263 miles before mine failed. IN the midwest too. Heh.

 

[SaturdaysGS]

I forgot to add, is there any downside, or side effects from running the fuel pump in high? Like, could I leave it like this for however long, or should I get a resistor?

Get a resistor, no reason to keep the fuel pump running 100% at all times.

GM part cost @ a dealer around 40 bucks.

ED morad has used ones for around 20 bucks shipped.

Easy install. YOu can choose.

Also the GM one relocates it to the firewall instead of the wheel well.

This happened to me after MGM when I got back from the track at the hotel. Just replace the fuel pump resistor an you should be all set. You can also disconnect it and run it on a paperclip until you get the resistor. I wrapped mine in electrical tap and ran like that for a week.
