Question about 1992 GMC Sierra K1500

1 Answer

My 92 GMC Sierra starts and runs great for 5 to 10 minutes then chokes it self out like its getting too much fuel. I changed Cap, rotor, plugs,plug wires. Do I keep changing sensors and electronic valves until I find the right thing or is there something common that can cause this?

Hello, I recommend changing the fuel filter. Old trucks are known to do this and I found that changing the fuel filter helps alot. After the filter change add some fuel injector cleaner and put some gas in it and see if this helps. It would not hurt to change your air filter and change your oil. Always do the cheapest things first especially in this economy. If this does not help let me know. This could also be your fuel cut off solenoid. In most vehicles these get hot and the truck just shuts off and you think it may be a loose battery wire or bad spark plug gap; sometimes it's just this solenoid. You could replace it but you can only get them at a dealership and there not cheap. You could also bypass it but I do not recommend that becuase in a case of an accident the fuel will not be shut off. I hope this fixes your problem.

1998 gmc 4.3 starts up but loses power 3-5 mins later,will restart and run again for another short time,fuel filter has just been replaced.


Install a pressure gauge, start and run 3-5 minutes and watch the pressure. You should see the pressure maintain as it did when first started. If it begins to drop, the fuel pump has gotten weak and is starting to fail.
Let me know what you find.
Regards.
