Jeep will crank but not turn over without gas and rough idleing
My 98 jeep wrangler 4x4 will not turn over unless I give it gas. It cranks just fine. Also, once I have it running it is idleing rough in neutral and reverse. Im not sure what to do. I just had the transmition rebuilt and a new engine put in. i have heard that it could be the AIC, the fuel pump, or the coil. i dont know what to look at first.

Have your injectors, injector pump, fuel pump and filter checked. if you have a new motor, definitely check the fuel filter. Also, you could have a relay or sensor, have a tech put a diagnostic machine on it to check your electrical system.

cranks ok> / not stated, and is 100% #1 key fact. ill guess (daft) it cranks OK. so check fluid levels(oil tops list ) then fuses.we test them. then scan it. all modern cars same. deal.
if it dont crank, "my starter is silent or just clicks) then that be a horse of a different color. dead battery ? charge system failure, starter bad? PRNDL (p/n switches bad )try cranking in neutral yet my wrangler is 6 speed stick with a clutch switch that too, is different. even green battery lugs,.got those?
will not crank or cranks perfect but will not start which is it??????????????????????????/
Yes...check the pump, filter and output. Also check the ballast resistor for the pump. Stop pouring fuel into the cylinder...instead, use carb cleaner and spray into throttle body (excess fuel in one cyl will contaminate your engine oil). If it runs normally after you get it started likely the pump is good (unless you have problems at high rpm's under power) Regulator is likely good as well...default is to more fuel not less.
