    Hmm

    Hi, my 91 cherokee 4.0 h.o. cranks at least 10 times before starting, hot or cold, changed plugs, filters, all the usual tune up stuff, still have the same problem, anybody got one with same trouble?, anybody know how to fix it? Oh yeah, a/c works fine (haha).

    Fuel pump leaking back?
    My doctor gave me six months to live, but when I couldn't pay the bill he gave me six months more.

    With a name like gmac why are you driving a Jeep? You should be in a Blazer.

    That's a classic Crysler/Jeep problem. My Dodge Ram did the same thing. I think sometimes the fuel drains back like Spotts said.

    i've got a 2000 jeep laredo , it does the same thing. had the fuel pump changed but it didn't help any. also plugs and filter. can't give any advice on fixing . if you find out what it is let me know.i got the same engine as you do , i think.

    first: use only hi grade gas. it will start better and perform much better. mileage versus dollars is about the same. second: turn ign to on and wait for fuel pump and anti lock brake pump to stop (if equiped), set em brake to shut off running lights, shut off hvac. now start

    also under the coil is an ign module which may be source of problem

    i had a 90 with 350,000 kms on it when i sold it.it is still on the road

    Not related to your problem,but today I delivered a condenser to job site in my old 79 J-10. Siding installer wanted to hook up back bumpers and pull. He had a Blazer with a 4cyl. My J-10 has a 360v-8. I had to look back to see if he was still there.LOL He wasn't so smug when I got thru dragging him around the house. Most fun I've had in a while on the job site.

    test the fuel pump leak down with a fuel presure guage it should'nt drop more than 10-15psi after the fuel pump stops when just turning ign on if it does most likely ck valve in fuel pump bad
