Over the weekend i went out on a few trails and through a little mud. On my way back home my rear driveshaft dropped out. I replaced the 2 u joints and thats all good now. When i went to start my jeep it kept stuttering. Found out that my distributor where it attaches to the motor was cracked. Got that replaced and now its hard to get it even started. When i get it started, it idles low and when u drive it, it doesnt seem to be gettin enough power. Had my mechanic lookk at it and he said it could be the fuel filter. Tried that and still didnt solve the problem. He checked my fuel pressure and it was at mid 20's while ideling and barely reached 30 on throttle. What else could it be? He mentioned that it might be the fuel pump.
