1995 cherokee 4.0. been sitting for a year or so. I went to start it and it had no fuel pressure. I did all of the usual checks: relay, fuel pressure and voltage check at pump. other then no fuel pressure everything checked out good. So like you are thinking I changed the fuel pump. After the install it ran great for a day. I parked it last night and went to move it this morning I was back to the same problem. Any help or hints are welcome.

 

Check this out, my 95 did the same crap. Changed ignition switch, new fuel pump, filter, coil, some days she would run great, some days nothing. Turned out that the cps plug (from to Jeep to dizzy)
passenger side had gotten oily and the plastic had pulled back and was making contact with the other wires, cleaned and seperated them taped them up to keep em seperated, no problems. I suppose it was causing a ground, which put the Jeep in no start, no spark.
also it will shut down the fuel pump, and you will have a no pressure on the fuel rail, I replaced a 1yr Bosch fuel pump cause of misdiagonsis of a faulty fuel pump. I kept the old one, glad I did

 

Glad you figured yours out. I am going look into this now. I really did not want to pull the pump again. ended up pulling the whole tank cause I could not get the new pump to sit properly.

 

Yuck, does yours not have the access panel on the front of the tank. What I do with mine is Jack up the rear a bit, set it on Jack stands on the rail, not axle. Lower it back down to where the rear is at droop, it allows much more access. Especially if your like factory

 

That would give more room. I am stock and had it on ramps. even with it out it took 2 of us. I have ordered a CPS and going to try it. good thing it is just my toy vehicle and not my daily driver

 

Yeah for real get some of the tall Jack stands crank that baby up at the axle, enough that your tires are in the air, if you want maxamine droop take off your rear tires. Don't worry about your axle, the sway bar won't let it hit the ground or nothing place jack stands on your frame railing in front of the leaf spring eye. Let the jack down slowly, the axle will drop down but the Jeep body will remain at jacked height. Hope this helps

 

This was mine dropped notice how low the differential is

 

Since it's a 95, it may have a fuel pump resistor that's bad. Usually that will allow it to start, but die right after that.

Tgramsey, where's the shock in that photo?

 

hopefully I will not need to remove the fuel pump again. the CPS doesnt look to bad to get to. might be a pain getting it back in. Rock Auto should have it here in a few days.

 

I was finally able to do a spark test and yes it is getting a spark. still hoping the CPS fixes the problem. worth a try for $20.

 

From my understanding the 95 does not have a resistor. it was mainly used to reduce feed back noise from the fuel pump on a lower voltage. on the 95 ( maybe even older) they decided to run the pumps on 12 volt. that's what I read on another forum.

 

also where my jeep was sitting, when I changed the pump, was not an ideal place to work on anything. it is now sitting on concret under a carport. also have power and air tools and better Jack's and stands. I may end up pulling the pump again and this time I will be ready for it

 

what is the correct voltage reading at the fuel pump? it is a 3 prong plug. Right now I am reading 12, 6 and 0 for the few seconds when starting. i know the 12v and 0v is right. not sure about the 6v.

 

Not correct. 95 and earlier had resistors except for 1987s. And then they came out with a retrofit kit for those.

 

thanks, I am going to look more into this and see if that's my problem.
