I turn the key to on position to where the fuel pumps cut on and they run for like 30 minutes to an hour and then they'll shut off and my truck will crank fine. It won't crank if fuel pumps are still running, but sometimes it will and the check engine light will be on which makes it run kind of funny but the check engine light will go off and it runs perfect! But now fuel pumps keep killing my battery and it's just getting very anoyying now and I've replaced a lot of stuff to try to fix it. Ford place told me it was the check valves in the fuel pumps and told me I needed to get new ones so I did, didn't work. Next I replaced the fuel pressure regulater and checked all fuses and relays and still didn't work. Then I was told it could be the fuel injectors, so I replaced them and the fuel filter, still same problem. I checked around online and some people were having sort of the same problem and they said it was the PCM OR ECM. I took the computer out and checked it and replaced all three capacitors because one of them was like blown I guess so I just went ahead and replaced all of them in there. Now I'm out of ideas. Can you help me please?
have the same problem?
