Discussion Starter #1 (Edited)
I have a '94 YJ 4cyl. wi/ 189k miles that does not like to start. I have to sit there and crank if forever before it thinks about starting, but once it does start, it runs very strong. It is just not the smoothest,but I think that is more of a vacuum problem. I needs some suggestions. Yes, the starter is good b/c I have changed twice. Tune-ups don't always help either. Thanks

try squirting it with starting fluid and see if it starts right up, if so, I'd lean toward it being a fuel issue.

Check fuel pressure blead down.

Attach fuel pressure guage and see if the pressure holds for 1, 5 and 10 mintues. You should not see a bleed dpwn of more than a few PSI.

If it bleeds down-your pump may be on the way out, or your(s) line is leaking
