Ok so I am going to go with the AC Delco pump. Another question. The problem with my car is that after driving for a while, 20 min or longer, if I turn off the car then the car wont start for about an hour. If I spray starting fluid the car will start at any time. My fuel pressure is 20 psi with just the pump running and 30 psi when the car is running and the pressure is steady, not dying off. The pressure should be 42 to 47 according the to manual. I have the factory service manual and have followed a flow chart which says if the fuel lines are not clogged and the fuel pulse dampener is working well I have a faulty fuel pump. I am wondering how I can tell if my fuel pulse dampener isn’t working. I figured to check anything I have to drop the tank so I will replace the fuel pump anyways (130,000 miles), should I replace the fuel pulse dampener as well and call it all good? I can’t find an AC Delco one but I did find a Carter fuel pulse dampener for 30 dollars.
