1995 Dodge Caravan 6 cyl Front Wheel Drive Automatic

the van left me set one day. The fuel pump wasnt turning on. I had it hauled home, it sat for about 3 days and I went out and then the fuel pump started to work. I didnt want to get stranded again so I changed the fuel pump and filter. Now it is hard to start. I didnt check the pump pressure because I dont know how many lbs it should push.

48-55p.S.I. Is the specs on any Chrysler higher pressure fuel system. It may be storing a fault code. There could be another problem. A scanner plugs into the OBD or Chrysler connector.
From there the codes can be read. I hope the new pump came with a new pick-up screen.

Your welcome of course, go over your work and the entire system. The pressure is supposed to hold at or around the high pressure the new pump should be running at. If there is even a small leak the pressure drops off immediately after you shut the engine down, and thus a long cranking time to get the pressure up again. So make sure that it holds at least 10 minutes or so before dropping back down, or this would indicate a leak somewhere at the work you just did, or at another spot you haven't even touched.
It should be running at 48-55psi and hold for a few minutes after you shut it down. If not inspect it visibly for air leaks(fuel leak). Ok Then check it for codes using thescan tool. It may be something else. Autozone has a scanner and will help you with this, give them a call. If you need help, just let me know. Bye for now.

I check for leaks, none. I checked pressure, it had 37 lbs and when I turned it off it dropped to 0 automatically. Since the fuel pump had a year warranty I dropped the tank took it out and took it back for another new pump.I put it in, relaced the inline filter again and it starts and runs fine. It was a faulty fuel pump. Thank you again for the advise

I was thinking to ask you about where you got the pump because I've changed so many new after market pumps because of a bad check valve that is sometimes non-existant in the other ones. Good for you, now your that much more experienced. I read a bulletin about a small wiring harness that was a problem but it was for a rattling noise, not low pressure. Your pretty good with auto repair, later, joe
And your welcome, I never forgot about you.
