Question about 1993 GMC Sierra K1500

1 Answer

Shuts off while driving

I left a voice message on the number that you listed with my call back phone number. The Fuel pump was replaced 2 years ago, and I do not think this is a fuel issue. When the fuel pump went bad, the vehicle bucked and kicked as the engine lost fuel pressure. This problem the engine instantaneously shuts off and will restart immediately. It has occured both on a cold engine and at operating temperature.

    I found the issue after several months. I removed all fuses and relays, cleaned the contacts and reinstalled. The problem has not returned and it have been about 2 months. Thanks to all who provided solutions.

Try running two new ground wires from your battery to your firewall and one more to your block you could have a pretty good short that is grounding out your ignition.

Rough idle during initial startup, then sometimes sputters and shuts off after 20 minutes of normal driving. Happens every few days or so.

I would go after the injectors. Check and see if there is a place around you that clean them. It is way cheaper to clean than replace these. Your's run about $80 a piece.

Shuts off while driving but starts up

Sounds like it's not getting fuel. Check fuel pressure at the fuel rail. If low, make sure the pump is running. If the pump is running, but no pressure at the rail, check fuel, filter. Get back to us with result of these checks.

I have an 89 Olds 98 Regency. The fuel pump comes on with the key then shuts off less than a second later. Does the fuel pump need to be replaced or is there a relay module that could possibly be the...

The fuel pump will come on then, shut off when the key is placed in the ON position, this is normal. What is not normal, is when the key is turned to start the engine, and the fuel pump does not run when the engine is running at the same time. The initial power up you hear is a prime function that all vehicles have.

I will be driving down the road and the car shuts down.The doors unlock and 2 secs later the car just shuts off. About 3 weeks ago They replaced my fuel pump. It did it once right after I got the car back,...

that valve that you seen is to your fuel rail and may have to be bleed. So it sounds like when you had a fuel pump problem during that time you were getting air in your fuel system. After replacing the fuel pump they did not properly bleed your fuel system to the correct pounds of pressure.
