1990 k5 trouble
Hey everyone I do not know much at all about trucks. my blazer will not run. It will start up and die instantly. The only way itll stay running is if i keep pumping the gas peddle and even then it still barley runs. I have only replaced the fuel filter and the fuel pump is working fine and ive also cleaned the injectors. What could be the problem?
Thanks Dustin

Try rebuilding the fuel regulator, its behind the injectors. Careful it has a spring in it, you can find on line how to do it.

Could be the coolant temperature sensor that is causing your problem. It is up by the thermostat housing, to the left of it.

I always try to start with the obvious. Fuel and spark. A new pump doesn't always mean good pressure. Do you have a fuel pressure gauge? Inspect the whole ignition system. Everything, wires, cap/rotor. Then move on to the others, sensors and such. Good luck
