Hi. My 1996 gmc sierra 1500 I was driving down the freeway and truck died. A couple minutes later it would start. I got home turned it off and it won't start. Got fuel up to the throttle body
Changed filter and regulator And
pump is running. Starting fluid or gas
in throttle body will start and run til
it's gone. Help! Please
take a volt meter and test your started cables.
Sounds like fuel pump is bad. All because it ( the fuel pump ) is running does not mean there is enough fuel pressure on the fuel rail for injectors to operate properly. Test the fuel pressure at fuel rail. What psi is it showing? Also is it a vortec engine? If so do not spray anything in the throttle body. It is plastic and has spider injectors in it. If it back fires thru intake even just one little time you will be replacing all the injectors and the upper intake.
