I'm having some serious starting issues. I have a 91 4.0 and I'm assuming its a HO. Can codes be pulled on these trucks for this year like on a cherokee. 3 key turns to on and flashing codes? I tried it with no luck. I'm not getting any start after replacing the cps, pump, filter. help a brotha out!!

not in this post. It is showing about 40psi during cranking.

ok, so I replaced cps, nothing. still cranking and not starting. AGain, when I check hte fuel pressure I'm good. I can use the bleeder on the fuel pressure gauge and keep it running. So, I'm assuming spark is good, and i'm getting good psi to the rail, so are the injectors my last option? is there a fuse for the injectors? Module?

I am getting 40psi during cranking.

sorry, its a 91 6cyl, gas is fresh, its the same gas I'm using to prime it with. Which sensors shoudl I be checking?

so, I finally have pressure at the fuel rail. But now it won't run. Bought this truck a while back and just now started messing with it. Initially had no fuel pressure. Now I have fuel pressure but I'm not getting any starting. I can prime it and keep priming it and it will run, but when I try to hit the accerator it just pops and cracks/stumbles and dies. The exhaust is a little smashed just below the header, but no narrower than a bout an inch and a half. I'm kinda at a loss on this one.

Anyone build their own tail lights? I've seen some on xj's that could work on mj's. I may take this project on as the only tail lights i've found are going for 75 bones or more.

I was going to ask how the paint held up, but it looks like you have repainted

replaced the pump but now i have a leak at the filter. it made pressure on initial start attempt. then nothing. feels like theres a clog at the filter but didnt have time to check

Whats the highest we can lift these trucks before driveshaft mods are necessary?

got a new fuel pump and we're good to go, thanks for all the help

ok, i'll test those tomorrow morning. the switch is at the bottom of the column in the cab?

where is the switch. the relay is clicking when i turn the truck on

i'm sorry i meant i think my pump is bad. nothing to the rail unless i turn the key back and forth a few times
