97 JGC hard starts
 
Hello,

I just replaced the plugs and distributer cap and rotor on a 97 Jeep Grand
Cherokee because it was starting hard. It still starts hard after
replacing those things. Usually I have to crank it over for a long time
for it to start. Once it is running it runs and drives great. If the
engine is already warm, it starts up fine, I only have trouble when it
sits over night or for a while during the day...

Any ideas of what else I could check?

Re: 97 JGC hard starts
 
You may have a bad check valve, allowing your fuel pressure to
bleed off overnight. Next time you attempt to start it, instead of
cranking the engine just turn on the ignition switch, and wait two
seconds for the fuel pump to automatically turn off, switch the ignition
off, and back on again, doing this for at least five more times and you
should have gasoline back at the injectors.

Thanks for the info...the checkvalve is part of the fuel pump right? Would
I have to drop the tank to get the pump out?

Thanks

Re: 97 JGC hard starts
 
There is also a regulator on the fuel rail usually with a check valve
for the return line so you would need to first check the pressure bleed
off, then isolate which way it is going down if it is indeed the
trouble. Bill's test will tell you for sure if that is the problem. It
made no difference in our 4.0.

Our Cherokee got noticeably faster starting in the mornings when I
replaced the ratty ground strap between the engine and the firewall. A
quick test for that is to run a booster cable from the battery negative
to the body and see if it starts right up after that.

Re: 97 JGC hard starts
 
I have a Jeep TJ 97, and I got the same problem. I did the test as you
described below and the engine started fast, just as it did some time ago.
So, the question I have, were is this valve and is it easy to replace?
