i just put a new one in and im getting no pressure at all the only thing i can think is that the new pump had no markings for positive and negitive. maybe i switched them??? i know there isnt a way to switch them but i had to screw on the male conector things to the pump im gonnna go out a rip it all apart again and see whats up, im so frustrated!!!!

test your wires first before you go ripping into it. make sure you have power and its hooked to the right wire.

X2, you may have a bad fuse.

this is when you know you need a break...bro take your time, go to bed and get up in the morning all fresh and ready and hit it. i'll be on in the am hours and im sure we can figure this out...

yeah. good idea on the break... i feel much better

i get off work at 330 so i think when i get home i will check the lines and see what going on, this all started when i was driving. It was going fine and all of a sudden started bucking pretty hard an died. im reall hoping i can figure it out soon its 28* out and some clouds in sight haha.

Have you checked the injectors, maybe one or more of them are clogged or just not doing their job.

hmmmm 28 psi I can't remember for the life of me what you are supposed to have I guess I am getting old and number are escaping me but I want to say it is like 35 PSI so it isn't a huge difference.

On my waggy I had a bucking problem that was weird also. Not trying to say mine is the same but it would buck and die at times just from a idle. Then sometimes it would start fine and run like a champ then in the middle of driving it would have a feel of like a gear slipping and buck a lil when going like 30 mph. My problem was just a simple unplugging and then plugging back in the CPS. Sounds weird I know what that lil sensor cause all kinds of weird hard to diagnose problems when it is degraded. My jeep has been running like a champ now for 6 month with no further problems!

inst the cps plug near the firewall with 2 prongs? if so i have tryed disonecting that and plugging it back in but there is no change. when i get it started it will somtimes idle and sometimes it wont. how would i check my injectors and if it is clogged somewhere were would be the best place to start?

mudallday

any ideas?

mudallday

perfect, its snowing..... i need this thing running.

try to pull the vacuum line off the fuel pressure regulator and see if the pressure goes up. if it does not go up you may need a new regulator. At least that is how you test the regulator on fuel injected fords...

ITS FIXED... for anyone who has this problem here was my solution... on the driverside inside the fender right by the air box there is two black and orange wires that both plug into this ceramic thing. its purpose is to quiet the fuel pump down. they started somtime in 87 to see if thats your problem just wire the two wires togother, befor it would die after about 5 seconds thats becouse after a few seconds it switches to a lower volt i think. hope this helps someone... thanks for all your guys help

cherokee4meplz

good deal. I was just looking at that ceramic thingy today wondering WTF it was.
