Just replaced "fuel pump", it cranks but will not turn over. Can anyone tell me what direction to go now? The Jeep has been sitting for about 3 months. Thanks > Just replaced "fuel pump", it cranks but will not turn over. Can > anyone tell me what direction to go now? The Jeep has been sitting for > about 3 months. Thanks Maybe... If you turn the key just to 'run', you should hear the fuel pump prime the line. If not, then you have a pump or power issue. One sneaky one that can happen is when they do the emergency brake recall, they can forget to hook a black wire up to the bolt that holds the e-brake onto the body. This wire is the fuel pump ground. Another one is the wire mesh strap that runs from the back of the engine head to the firewall on the 4.0 engine or maybe one from the battery to the firewall or fender can be bad. When this happens the computer wont turn on. To test, I run a booster cable from the battery negative to the body.

It cranks; it just doesn't want to turn over. I'll get back to you. Thanks Again Take a look at the crank sensor. It should be on the end of the tranny. >On Aug 17, 4:48 pm, DianaDBr...@yahoo.com wrote: >> Just replaced "fuel pump", it cranks but will not turn over.

Follow the wire from it and clean the connection. They are notorious for a bad connection there. Does the pump turn on for 2 seconds when you put the key to run?

I don't hear the pump run at all. THere was a black wire that ran down to the tank flange along with the orange and pink wires that ran inside. The black wire was not attached. It had a bade connector that had rusted off. I could not find where it had been attached, so I put on a new connector, and attached it to one of the flange bolts. I have also run a jumper cable from the battery negative to the body, and from the tank flange to the frame. Still no sound from the pump. I'm at a loss. >Hello again. >I don't hear the pump run at all. THere was a black wire that ran down [quoted text clipped - 5 lines] >from the tank flange to the frame. Still no sound from the pump. I'm >at a loss. Put a test lamp (just a 12V bulb with leads) between the power wire and the ground... if it doesn't light up, check the fuel pump relay and the fuse and fusible links. If it lights up, you gotta pull that pump again. --scott  Signature"C'est un Nagra. C'est suisse, et tres, tres precis." >> Hello again. >> I don't hear the pump run at all.

My CJ7 has one. Mike 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT's - Gone to the rust pile... Canadian Off Road Trips Photos: Non members can still view!

Your terminology is wrong. "Cranking" and "turning over" are the same thing. Your car WILL turn over, it just won't FIRE UP.

Thanks Well, measure the fuel pressure. Is there any pressure at the rail? If there isn't, the pump is either not working, or your filter is plugged pretty solid, or the regulator is gone. If you pinch the regulator return hose, and the pressure comes up, the regulator is bad. If it doesn't, change the filter and check the voltage on the pump. If there is no voltage at the pump, it won't turn. If it's got voltage and still isn't turning, you got a bum one and need to take it back. If you DO have correct pressure at the rail and it won't start, yo have a problem that isn't your fuel delivery system... you need to make sure you have spark next if that's the case. --scott Signature"C'est un Nagra.

Thanks It sounds like you are not getting any spark to plugs.It could be a bad ignition module or a pick up coil in the distrbutor.If the vehicle has a lot of miles on it replace both, Good luck... |
