Hello Guys,

Im having a funny issue with a 95 blazer 4 door lt. That i picked up for dirt cheap. When I got it there was a no start issue with it. Priming the intake wouldnt work for starting it. It would start then sputter out though.

So I changed the fuel filter, it seemed pretty plugged up. But at least now if i prime the intake it will start and run decent. But the check engine light will come on after a while.

I plugged a fuel pressure tester into the test port by the distributor. It is getting the range of 40 - 45 psi. This doesnt seem like enough pressure during pump prime is it?

I dont have a code reader. So i have no idea what the check engine is saying. Im wondering if there is anything else that im missing. I was going to change the fpr at the same time as the pump. The fuel pump relay is good, and can hear the pump start. But that reading from what i have seen is to low for a start.

Anyway i have the tank almost off. Are there any other sensors that I might be missing? If so where would i find them on this thing. I am not used to these vortec engines.

 

ps sorry for starting a duplicate thread. Just noticed another post with the same issue.

 

Read my thread here and see if any of it rings a bell.

Yeah thats it I already dropped the tank, just waiting on the fuel pump to arrive now.

 

Just so everyone that helped out knows. Changing the fuel pump fixed my issue. Thanks everyone.

 

Thanks for letting us know. Glad you got it fixed. I fought myself about doing the pump but after a while all arrows were pointing to the culprit. Mine is doing just fine now.
