I have a 1997 Jeep Cherokee with 298K and was still going strong until yesterday afternoon. I need help solving a problem. I was driving when my Jeep suddenly died, then started again, then died. I had to pull over for a minute, it started again...drove for several miles, then it shuddered and died. After a few seconds, it started, drove, then died. After an hour waiting for a tow, it started , dove 2 miles, then died. The tow came and took us home. Any ideas what the problem IS or could be? I may have a few. Help needed before throwing away several hundred $$ by unnecessarily going to "the local garage". Thanks in advance!

If you tested your Jeep, you wouldn't be "throwing away" any money.

You can buy a fuel pressure gauge at Harbor Freight for $10. While you are there, buy a test-light for $5. These two tools will diagnose 90% of your Jeep.

Test fuel pressure at the test-port on the fuel rail.

Test for spark... pull the coil wire off and spin the engine.

No spark??? The green/orange wire should have battery voltage from the ASD relay while cranking. Have voltage???

Connect the test light clamp to the (+) terminal and check the other wire on the coil... it should "pulse" ground while the engine is cranking.

Check this stuff and call me back.

Turned out to be the CPS

 

cps cam shaft pasision sensor?
