Please help, I have a 94 grand cherokee larado with a 5.2l v8. It seems to be having some fuel issues I think, this is what I've done so far,
Replaced brake booster due to vacuum leak coming from inside it
Replaced fuel pump and filter
Tune up, plugs wires cap and rotor.
Replaced disc in distributor under rotor, I can't remember what it's called.
I'm getting spark to the plugs, but when it did run it would idle rough, die after about 3 or 4 mins of idle and if I drove it, braking made it stall..I know three mechanics and none of them can pin point the problem. I don't want to break down and bring it to a shop or dealer so please help me figure this out. I'm pretty sure it's a fuel issue so are there any other fuel filters maybe on the vehicle other than the one above the rear axle? I've been reading a lot about crank pos sensors, could my problem be there? And also it's not throwing any codes so I'm kinda blind in that sense as well..please help me triangulate the problem.

 

Welcome to the forum.

Is it throwing any codes?
what is the fuel pressure?

 

No check engine light on but when i turn the key to the on position the abs light stays on for about 3 seconds. And i haven't checked the fuel pressure. I don't gave a gauge.
