89 jeep wrangler, starting problems

Sounds like a stuck or defective float.(perhaps a hole in it). Also check the needle valve for operation and if its installed correctly. That is connected to the float

the condensor if it has one if the electronic module thats normally mounted under the coil

check the crank shaft sensor. if the sensor is bad the jeep won't start.

It sounds like your new crank sensor is defective. It should be under warranty.

Problem is likely either a worn shift fork or bad synchro (both inside the transmission) It's unlikely that you have a clutch problem otherwise the problem would be with first and reverse and shifting other gears would also be difficult.

Sounds like the drainback valve inside the pump is shot...try just turning the key on and waiting a minute and see if it starts that way.

One possible explanation for this is that the crankshaft position sensor is going bad.

sounds like a battery or ground connection problem , disconnect and clean the inside of the battery cables and the posts,tighter securely . If that doesn't do it remove the other end of the negative cable and clean the cable end and the metal that it bolts to.

Have you checked the tightness and/or tried replacing the alternator/drive belt? I have an 89 cherokee and I had the excat same problem .. I replaced my alternator drivebelt and wala .. fixed .. Crayz

Hello, We used to have this very same problem with our Mini! what you have here or havn't as the case may be is a good Earth to the Engine Starter and Battery so your cables are doing an overload job. Take an extra earth strap from engine/starter direct to battery!
Good Luck!
