My 1997 jeep grand cherokee cuts off while driving or wont crank
If you have the 4.0l inline 6 and you mean buy "cuts off" that the engine stalls at the stop light or refuses to start from time to time...this engine has a well know problem with the crank position sensor, if it is bad or the connection loose or incorrect, you will have this problem
1997 jeep cherokee no crank
No Crank?
This procedure usually works:
·Check the battery cable connections:
Make sure the positive cable, makes a good connection at the battery and at the starter. Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine.
·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.
·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's bendix gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck bendix gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.
Automatic transmission shifts down on its own
the kick down cable must have slack, at idle.
if not its bad. (end to end, something is wrong with it)
this cable is for passing gear.
you jam the throttle and the tranny then down shifts.
called, kickdown, detent and TV cable.
if the cable rusts it can in fact rust , pulled. and now in passing gear full time. or it can stick driving do to rust.
what i do is make sure the trans, end of cable the detent rod is not sticking, if that is ok, , get a new cable.
When i press on brakes
Brake pads are worn. That noise is the sound of the backing plate for the brake pads hitting the rotors. You will need to replace the pads and probablt the rotors. When the brakes go metal to metal like that it typically destroys the rotor.
What would cause the idle to drop to the point of cutting off? Would that be the throttle position sensor or what?
fuel filter is somewhat built into the pump and installed within the tank. Periodic replacement isn't necessary and I'm sure the filter itself and getting a mechanic to drop the tank will be very expensive.
what did you do with a "tune up" ? gotta go retrace your work and make sure the plug gaps are correct etc.
if a check engine light went on after your "tune up" then you need to find the trouble code with a scanner and that will help you in the direction you need to go. Free trouble code scan at my local autozone or advance auto parts or even aamco transmission shops
Diagram spark plug wiring
my guess, is you removed them and didnt mark them?
the firing order?
what engine, there are 5.
to do this , one need to know 5 things.
2.5L, 2.8L, 4.0L and 5.2/5.9L engine displacements.
the distributor rotation direction CCW, or CW
and last the firing order, sometimes marked clearly on the intake manifold.
you must now where #1 cylinder is (always most front)
1989-98 2.5L Engine firing order: 1-3-4-2 Distributor rotation: Clockwise
2.8L Engine firing order: 1-2-3-4-5-6 Distributor rotation: Clockwise
4.0L Engine firing order: 1-5-3-6-2-4 Distributor rotation: Clockwise
5.2L and 5.9L Engine firing order: 1-8-4-3-6-5-7-2 Distributor rotation: Clockwise
on a v6/v8 one cylinder is more forward. this is #1, look carefully.
