Without actually looking at the jeep, this is a shot in the dark. Replace the crank sensor (if it's bad, you will get no spark or fuel pulse). It is located on the tranny bell housing on the left side.

Doesn't start on first turn, by 2nd or 3rd starts. Idles rough.


Battery should be around 12V the alternator puts out 14V. Sounds like a fuel problem, leaking injectors or injector's O-rings. Weak or faulty fuel pump, clogged fuel filter, faulty fuel regulator. Try this, when starting the car while cold. Put the key all the way to the ON position, wait five to ten seconds then crank the car to start. It should start the first time the longer you give it the more fuel pressure there will be to start the car.

2001 Jeep Cherokee Classic shakes and sputters when recranked after driving. Only does it once it's been driven somewhere and ignition is killed, then recranked. Doing it about a week then check engine...


Sounds like a fuel/air problem. Replace fuel filter, check/replace air filter and spark plugs, complete the tuneup and see what happens. If it still happens then suspect injectors. Run cleaner through a tank of gas. If still the same take it to a shop that can plug into your vehicle and verify injectors performance.

2001 jeep Grand Cherokee fuel injectors


check the injectors on that bank for pulses.. a regular 12v text light will do it should flash when cranking... its very possible that the crank sensor or camshaft sensor on the replacement engine is bad and giving you all the problems you have now.. are you using the original injectors? if you have injector pulses then check the coil for pulses the same way.. btw make sure you have 12v to them even before cranking engine could be a bad asd relay..wet plugs on one bank would also indicate a possible leaking injector and basicly draing the fuel starving the oposite bank for fuel.. to verify that the rail must be lifted by removing all 4 bolts make sure the clips hold the injectors firmly and turn the key to run but dont crank it then look for fuel leakin from bottom of injector(s) any drips is a bad injector..
