When I go to start up my blazer in the morning, Or after a good amount of time, it has a hard time starting without lightly Pumping the gas. After running the car for even a few minutes you can turn the car off and start it right back up with no trouble. I have no clue where to start other than I timed it, new plugs and wires, distributor cap and rotor, other than that it runs perfect I just want it to start better.

 

FYI, the pumping of the gas thing is in your head. Pumping the pedal on a fuel injected engine does nothing. Its the fact that you are holding open the throttle plates and letting in more air that's making it easy to start.

I would start with the easy things, fuel pressure test first off

 

what ohsofly said.. pumping gas only works on carbonated engines. its opposite for FI engines, you hold the pedal down.

But that being said. fuel pressure test, like he said also

 

i agree. you'll get some good info there. could be simple as a fuel filter too.

question for the fuel pressure guys, i just changed out my spider injector on a 4.3 1994 T10, fuel filter as well, should i get a fuel pressure test? and where would the regulator be located for fuel pressure? one last one, or the fuel pumps on these things usually quite audible, annoying if you will? or is mine troubled?

thanks folks
