Question for the group:

I have an 88 cherokee with the 4.0. It has been in the garage all winter as the water pump camp apart in the fall. Little by little I got it back together and a month ago the job was done. The jeep started right up, and I drove it around the block a few times. It hasn't started since.

I put a pressure gauge on the fuel rail and it has the required 38 or so PSI. It's getting spark, which I know b/c my timing light is strobing. Spraying starter fluid into the throttle body or air cleaner doesn't seem to have any effect.

I'm stumped. Any ideas?
