won't start problem
 

Went on a wheeling trip this weekend and had some problems with the
'95 YJ, 2.5L, AX5. The check engine light would not turn on and the
fuel pump was not activating. Engine would turn over fine but would
not start. Also dash would illuminate, fuel gauge activated, etc. It
did start after trying many more times and once started would run
perfectly, no misses, no stalling, no hesitation. Any ideas? Thanks,
Neale

Might be but I think the check engine light and fuel pump should still
run for a short while with the key on RUN even if the CPS is bad. I
don't know, maybe a bad ground or bad computer?

I've had a ground problem with my fuel pump but it did affect the gas
gauge, the gas gauge pegs to full when the fuel pump cuts out. I think
the check engine light acted as usual. You stated your gas gauge
activated so it could be another issue/ground
There is a fuel pump ground that's by the e-brake mounting brackets
on most YJs.


I havn't found the bad ground yet as my YJ has no grounds on the e
brake mounting cable.
