get another probley can get one from a junk yard and have it installed and torqued if crank shaft is ok

Do you like the vehicle? Are you mechanically inclined? Vacuum leaks are sometimes dificult to find. It could be a vacuum hose, a leaking intake or a blown gasket. Spray around the outside of the intake with a carb cleaner spray, look for any change in the engine, when it chages you have found the area of your leak

This sounds like the same problem I had with my 87 Jeep 2 door Cherokee Sport.Thought I had to replace the Fuel pump yet when I went under and pulled it out of the side of the tank I found that one of it's vacuum or return line had fallen/poped off. After I pushed the rubber tube line back on it's metal tube and pushed and remounted the pump back in the tank. Started up and it never ran better at any speed. Yea!!!!!

Pull the fuses and check the socket for power on the things that don't work. If there is no power at the fuse box there is a good change the stater igintion switch is toast. it is located on top of the steering colunm under the dash.usally less then 20 bucks All that you mentioned get power from this switch that goes to the fuse panel when you turn the key on

check comprsion that will tell you what cylinder

valve blow by or rings

Try this sealer first.

What is cps? Replace the fuel filter, it is cheap and will rule out one more thing.

needs shimmed or the bendix is bad in the starter and not allowing to release. most likely just needs shimmed if it's a new starter, however you can get a bad starter (new or rebuilt)

check ur fuel pressure i should be about 39 psi with hose off and about 31 with hose on if its lower then that take the cap off the gas line its a lil black cap and inside it looks like a stem for a bike or tire on truck turn key on and push stem in if it sprays alot of gas then idk but if it doesnt then u need a new fuel pump had same problem but mine was fuel pump and ignition switch maybe swap out ur ignition switch under ur steering wheel column its a lil black box with about 7 prongs on it when u disconnect if that dont work get some soap put around ur hoses and see if u have a leak soap will bubble if u do u will have to crank it til u see bubbles its just a few ideas i have a 87 jeep cherokee chief straight six w/lift pre-runnered out

The most common cause of this is that the Crankshaft position sensor is defective, (in bell housing rear of engine just over the starter) but you will need to do a fault code scan to confirm this on the computer control module.

You should take the car into a dealership for inspection. A guess is that the heater core started leaking coolant and that has shorted out the blower motor.

first thing you should do is get the code for what the vehicle say's is wrong..you can get a general diagnostic code by first locating the check engine light then put your key in the ignition (do not start the vehicle) now turn the key to the on position four times on the last turn leave the key in the on position and start counting how many times the check engine light blinks there will generaly be a two or three part code so there will be a slight pause in the blinking when this ocurse start the count over agian and so on..i suggest that you repeat this proces several time so that you know that you've got the correct code..then go online and find a jeep website or chrysler website that has a display of the codes and compair yours to that list to find what the diagnoses is...note sometimes the diagnosis is fairly vague..you may also try just replacing all of you fuel relay switches and the auto shutoff relay switch...also could just be a cloged fuel filter..but try the code first otherwise all your doing is fishing for the problem and using your money as the bait...

sounds like the master cyclinder is bad. this is a pretty easy fix . hope this helps
