Question about 1996 Jeep Grand Cherokee
I replacement the crankshaft positioning sensor yesterday.
When I tried to start it. It was hesitant so I gave it some gas and it stated on up. I drove it up the road about 2 1/2 miles and it was fine. Now this morning I went to start it and had the same issue didn't want to start unless I gave it some gas. Once it had cranked I left for work and got about a half mile down the road and it acted like it was going to die so I gave it a little gas but there wasn't any hope it cut off. I tried to restart but it wouldn't. Any advice?
Sounds like you are back at square one....Therefore, you need to re-test the old sensor to make sure it is bad, re-test the new one to make sure it is not either defective or that it isn't hitting the flywheel. I would go further and test the remainder of the sensors on the engine as well as it is possible that another item is bad. Also make sure your fuel pump is operating properly and has good pressure. No shop tech can do a repair without proper testing,(shops spend thousands of $ on test equipment for that reason) you can't either.
Most inexpensive manuals such as chiltons or haynes have instructions for testing, and for most tests except fuel pump pressure, you can do tests using any good digital multi-meter. From here, I can't responsibly tell you what needs to be fixed, but I can tell you what to do to find the problem....in your case testing!

I don't mean to be hurtfull but if you normally do not diagnose and repair you r own vehicle, you should search out the very best repair facillity nearest your home or work place before you may need one. Then if you only go there when the car problems are beyond your ability to resolve,stay with that place of business for a couple of years and give them a chance to prove themselves. Very few people do that. Now the fix! Not even the best repair faciltiy can give you an answer without having the veh and going on a road test with you driving and explaining the issuses. No road test,move on to the next shop on your list. You have to do your part. Tell them all the repairs done going back a year or so. Even if unrelated to current issues. Next be ready to spend some money and ask a lot of questions. What lead you to replace the cps?? Did it require any adjustment or just bolt on? Other things to consider. Gas filter -clogged,Throttle position sensor or Throttle Body -worn out, Other sensors related to Fuel Management. MAP,MAFS.MAT,MAF. You should start with a scan for codes keeping in mind most people think that tells you what and how to make the repairs but it does not, it's a starting point. A no start is as you know is a failure of at least only part in the vehicles may complex systems. It takes year or decades to become half decent at this type of repairs. Let us know how you make out
