I have a 1990 4.0 jeep cherokee that isn't getting fuel, I changed the fuel pump and fuel sensor as well as the fuel filter and some fuel line, but it doesn't seem to help much. It seems to have pressure at the fuel rail, but hardly any fuel gets there, just in spurts it seems and those are far apart, there is no electrical issues I can find except for a possible break at the fuel pump where I rewired it but I really doubt it.

I am sorry for this ramble, but I want my jeep to start running again.

Oh and there is gas in the tank in case you are wondering

 

Pressure at the rail but no spray from injectors? or pressure at the rail but no fuel?

 

pressure at the fuel rail, just a couple drops of fuel, at random times

 

Plugged injectors, or failing injectors? I had to do mine on my 89 and they were so terrible black gunk built up on all the flow nozzles

 

injectors are fine, I put gas in the throttle body and it runs like a charm

 

Until the fuel in the throttle body runs out?

 

Yes sorry should have clarified that

 

anyone else have an opinion????

 

So youve changed the inline filter? Is that backwards? They wont work backwards. Also did you change the in tank screen?

 

have you traced all the lines? none pinched? checked voltage at the pump?

 

ok so I went to the parts store because I didn't know what that screen was all about yeah apparently my old pump and the new one I got never had one so I will change that and then I will check the voltage the lines look fine no pinches

 

there is a fine screen that goes over the pump intake and is easily clogged by running empty, and it need to be changed when you change the fuel pump. It is quite common for people to replace the pump over a clogged screen

 

I had no screen, should I replace the pump again?

 

no you should check voltage at the pump then report back.

 

could it not be the ballast resistor?
