Happens all the time with 70's 80's and 90's GMC trucks. Replace the control module in the distributor cap.

Well if youare getting fuel then the only other problem is spark, check and inspect plugs and wires, to do a test remove a spark plug and with its wire still connected crank the motor, if you see spark then that's not the problem, but if you see no spark then it could be plugs,wires, and or dist cap

While the truck is running pull off one spark plug wire at a time from the distributor if the stalling gets worse the problem is not in that plug or wire if it don't change then the problem is in that plug or wire

2000 gmc Sierra starts but stalls


Check the fuel pressure while its running. It sounds like the fuel filter is stopping up. Fuel filter should be changed every 50 thousand miles or so. If the filter is bad it won't be long until the fuel pump has to be replaced (located inside the fuel tank)! It's a lot easier to replace the filter before the pump is damaged!

My gmc 4.3 stalls when warm and wont start without ether. then it runs fine


I had the exact problem with my 1993 chevy c1500. I found that the IAC was sticking so the engine would die at idle after warming up and the ignition module was pulsing the ECM intermittently after the engine warmed up so the fuel pump wasn't being turned on after the engine died....I replaced the ignition module and the IAC valve and all is good. I don't know if testing the ignition module reveals that it isn't sending pulses to the ECM.

1999 gmc sierra 2500 6 liter ran out of gas now won't start


If you are at or near the 100,000 mile mark then your fuel pump may have failed. If you remove the fuel filler cap and listen carefully at the filler neck while someone turns the ignition key to "run" [don't actually crank the engine] you should be able to hear the fuel pump buzz for about a second and a half as the key is turned On. If you don't hear the pump buzz then odds are your pump is dead. Your pump may have actually failed making it appear as though you ran out of fuel. Not to uncommon. Hope this helps and good luck!

1999 gmc sierra starting back firing and ran rough for a couple miles before stalling and now will not even try to fire. any good place to start looking? Thanks 4.8l v8 w/ auto


Sounds like the fuel pump. Simple check put key in ignition turn to on position Pump should buzz. Another way to check use a rag and hunt down schrater valve on the fuel rail on engine. Wear eye protection put rag around bottom of schrater valve and press down on valve. Fuel should shoot up at you if not your pump is bad.

A bad ignition module can give you fits!!!! Replace it even if it doesnt fix it! You will be glad you did! Most likely that is the problem ,however!

From red light truck started sputtering and and stalled out


Hello. The GMC Sierra has an electric fuel pump so you should ensure that its fuses and relays are working before checking it. You may need to clean your fuel pump or replace it if your gas tank is not empty, but your vehicle has difficulty getting fuel. The GMC Sierra comes in a variety of styles and trim levels that can affect the replacement fuel pump you choose.

I have a 2000 GMC Sierra, if I cannot hear the whirring sound of the fuel pump when the ignition is in the "on" position, would it be safe to assume that the fuel pump has failed? I was driving down the...


The fuel pump should only run for 2 seconds after the ignition is turned on unless the vehicle starts. Have someone lean under the truck while you turn on the ignition, you only have 2 seconds to hear it then you have to turn the ignition off again for 15 seconds. It's not unusual at all for a pump to go bad after 9 years and I think that's your problem. How many miles on it?

Stalling


Possibly faulty ignition module is the problem, stalls when engine is hot when you sit for a while it cools off and runs again until it heats up again, those are usually the symptoms of a bad ignition module and after a while it may give out all together and not run at all, usually if the module is at fault it shuts down the fuel pump so the engine don't load up with fuel, do to when engine continuously cranks over the injectors never stop squirting fuel and flood the engine do to lack of spark which is produced by the module, this could possibly be your problem.

1997 GMC K1500 4x4 5.7 ex.cab SFI injection system


fuel pump died replaced it truck ran poorly afterwards. Had a prussuer test done pump determend pump was no good. Put in another ran good for 2 days started running poorly hard to start no power. 2nd fuel pump. So i figure another bad new fuel pump wow changed it put in a third brand new fuel pump. Still will not eve start now. I had it tuned up 2 months ago new plugs rotor, cap, etc. put in a new fuel filter made sure it is on proper checked all connections for leaks. this cannot be a fuel pump problem now. no problem with the elctrical i figure i have great spark on ignition tester. I can hear the fuel pump prime when i turn the key. but when i went and checked the fuel port i had no pressure. When it is being cranked gas sews out of the test port. Also i dont if this is comon cause i used to turn my keyand go. but when i have someone turn the key and i listen at the gas tank whn the key is shut off i hear gs spraying back into the gas tank. So i am open for opinions.
