thejim42 Posted October 23, 2014 Posted October 23, 2014 I was teaching a friend how to drive stick in my truck because he just bought a new car and can't drive it. Well we were in a parking lot and he went to take off and the truck hiccupped a few times and then dies. I assumed he let the clutch out to quick but then it wouldnt start and I couldn't hear the fuel pump. Well I checked a few things tried switching a couple relays around and that didn't help. I then ran a jumper wire from the positive side of the battery down to the pump and it only clicked. But I only have .45 volts coming out of the relay. Any ideas?
MuddFoot Posted October 23, 2014 Posted October 23, 2014 what year mj and does it have the baliest resister. if so remove and put the 2 wires together
thejim42 Posted October 23, 2014 Author Posted October 23, 2014 88 4.0 5 speed. I tried the ballest resistor thing but that didn't work either
ftpiercecracker1 Posted October 24, 2014 Posted October 24, 2014 You put direct power to the pump and it still didnt work?
thejim42 Posted October 25, 2014 Author Posted October 25, 2014 Yupp. And when I replaced the pump it did the same thing. I checked continuity to ground and I have .05 ohms so I've got a good ground what are the chances the brand new pump I ordered is bad?
MuddFoot Posted October 25, 2014 Posted October 25, 2014 i just had a issue with the actual pump wires is redid them all and redid the ground to the pump i still have a bad sending unit but it runs great.
gogmorgo Posted October 25, 2014 Posted October 25, 2014 The ground for the pump is behind the driver's side tail light, and has been known to cause issues. Have you checked that?

thejim42 Posted October 28, 2014 Author Posted October 28, 2014 It was the pump. The new pump I got was no good. Exchanged it and now the truck is back on the road
HOrnbrod Posted October 28, 2014 Posted October 28, 2014 It was the pump. The new pump I got was no good. Exchanged it and now the truck is back on the road Which pump did you buy and exchange? Mfg and p/n? Might help others to avoid.
thejim42 Posted October 28, 2014 Author Posted October 28, 2014 I don't remember the part number. I exchanged the for the exact same pump but I think someone returned it because the pump that worked was wrapped in plastic and had caps on the top and bottom and the other one didn't. It was an airtex pump from autozone
