Re: help 95 blazer 4.3l fuel pressure problem
The fuel filter is new, I checked the psi right before the fuel filter and it said around 75 - 80 psi, but doesn't decrease at all. Then I checked at the fuel psi check spot behind the manafold and it is saying around 50 then drops to 30 pretty fast. I have the manafold taken off right now and it looks dry but crudded up tho. I checked the voltage at the spider line connector and it is giving me .54 vdc is that correct or totally wrong? I have replaced the FPR, the old one was bad. But Now I am lost at what could be the problem.
