I have a 96 S-10 4.3 with 136,000 miles on it. Friday when I tried to start it, it wouldn't. It has power and tries to turn over, but you have to crank it four or five times to get it to start. Once it starts it runs fine. I talked to my mechanic on the phone and he thinks it is a bad fuel pump. I tried replacing the fuel pump relay and it still acts up. I am just confused because once you get it to start, it runs just fine. I figured that if the pump was bad, it wouldn't run at all. Could the pump just be on the way out? Is there anything else I should check before spending $250 on the fuel pump and pulling the bed off to replace it? I have to get this thing fixed so I can sell it and pay for the 85 Jimmy I just bought! Any help will be greatly appreciated!
