Engine Performance problem
1990 GMC Sierra V8 Four Wheel Drive Automatic 95000 miles
Problem started with truck stalling out while driving. Would not re-start unless I squirted gas in the throttle body. Sometimes it would stay running and I could turn it off and restart it with no problem other times it would only run until the gas I squirted in the TB was used up. I replaced the fuel filter, no change. Checked fuel pressure, around 10PSI. Took it to a shop and they diagnosed it a bad fuel pump. Had the fuel pump and sending unit replaced. Picked up the truck, drove it home (stopped for gas) and had no problems. About an hour later I went out to the truck and it would not start. It's like something is preventing the injectors from pulsing. Any suggestions?
have the same problem?
