Hoping someone might have an answer for this! I have to turn the key 3 times in order to to prime it enough to start. I can hear the fuel pump kick on (it's in a fuel cell behind my seat). I have read a few YY threads about relays and ecm problems...not sure if the same applies for TJ's. Any help is appreciated!

Check the fuel pressur regulator. Seems to be a common problem allowing the fuel to drain back.

thank you, I will go look at that. for the next guy with a pressure regulator problem:

it's on top of the gas tank.


still looking for other possible solutions while I look into the regulator.

edit: here are some good threads I found regarding it

I wouldn't bother looking into other possible solutions, your problem is very likely a leaky check valve. There is one in both the fuel pressure regulator and fuel pump. The only other possible source of that problem is a leaky fuel injector... but which is far less likely. I've fixed this problem on two different Jeeps and both times it was the fuel pressure regulator.

Thanks Jerry. I'm gonna go to the local pull yard this afternoon and tear up a 97-01 cherokee; bring the whole sending unit home.
