While I was driving the engine just shut off. I'm still getting electrical power.
I try to start it but it just cranks. The ignition coil is new and new spark plugs.
I'm thinking crankshaft position sensor?. Help. What do y'all think?

 

are you getting fuel ? theres a valve on the fuel rail you can see if the pump is pumping

 

CPS is a good possibility. Verify fuel pressure and spark before you go firing the parts cannon.

If you have spark out of the coil, pop the distributor cap and take a look at the rotor. Every once in a while the rotor tip will break and the contact on the end is no longer making contact. Not a likely source of your problem, but it's free to check.

 

I'm getting fuel

 

im getting fuel and ignition coil and spark plugs are new. So I changed the cps and still nothing! Just cranks:/ any ideas?

 

What codes came up when you checked them ?

 

haven't checked it doesn't start and I can't find a obd 1 scanner anywhere for jeeps. And I can't drive it to autozone or anything

 

Could possibly be the camshaft position sensor, however I do not know if OBDI XJ's had one in the distributor.

For OBDII you can do the key turn thing and record the flash sequence to determine what the code is saying. Don't know about earlier systems.

Correction. You can do the key turn thing with OBDI XJ's. It is the same as OBDII. Without starting the engine, turn the key on, off, on, off then on and leave it there. Your engine check light will flash in a certain sequence. Refer to the code chart, the number of flashes. You can do a search online for OBDI codes. There is a list as well as more in depth instructions on how to do it. It is pretty simple. Go to......www.fixjeeps.com/jeeps-check-engine-codes.html
Read all about it.

 

And... this is why firing the parts cannon isn't a good idea.

Nice that you have fuel.

Do you have adequate fuel pressure?


(HINT: You don't know yet.)


It's also nice that your coil and plugs are new.

Do you have spark? Where? And when?

And have you done the free and very easy check of popping the distributor cap?

 

i tried that. And just tried it about 15 times after you mentioned it again. The ce light just stays on

 

yup popped the distributor cap already it's fine. Any other suggestions? Maybe cam sensor?

 

You've been asked two basic questions which you have not answered.


Why are you even here if you are going to ignore the advice given?

 

no spark. And yes fuel

 

My 1992 had the same problem, I started with replacing the crank shaft positioning sensor but in the end, it turned out to be the cam shaft positioning sensor. The car would run fine, then die for no reason, then it was impossible to start. I have a feeling my sensor was starting to go bad and was OK when cold, but after it warmed up, would fail with no notice. I believe if either the crank shaft or cam shaft positioning sensors go bad, the vehicle will not start. Good luck!

 

Dont need scanner.......
