I posted my question on the yahoo group, but it seems like most everyone is switching over to the forums. So I am going to give it a shot over here.
I have a 95 yj, over the last few days it had some sputtering, then it would stall out, after hitting the higher RPMs (3k+)
I was thinking it was the cat, falling apart from the inside and clogging the exhaust. But someone else suggested it may be the fuel pump.
I think I can diagnose the cat ok, but I don't know how to tell whether the fuel pump is functioning properly or not (hoping for an easy check).
The last time the engine stalled out I was not able to restart it, it is getting spark, and air going it but when I crank it, it sounds like it is starved for air/fuel. Just looking for some thoughts on what this may be and how to diagnose it.
Thanks
