4.3 GMC Sonoma won’t start again?
After reading all the answers to my won't start question I was sure it was the fuel pump! So 0. and two hours later the engine fired right up purred like a kitten. I dropped it into gear and blasted down the road for half a block when the engine started to serge then worsen then stopped before I could get it back to the house. Now it won't start unless I spray fuel into it and then it won't run for very long just stops. If I try to step on the gas it bogs and at half throttle it dies quickly not to start again. So only two things left, the inline fuel filter and the fuel pressure regulator???? Any one have any other ideas? No I did not buy a fuel pressure gauge.
