95 GRAND CHEROKEE NEW BATTERY,NEW STARTER.INTERMITTENLY STARTS.WHEN IT WONT START,THE ''DUMMY'' LIGHTS WONT EVEN COME ON.THEN OTHER TIMES IT WILL START NO PROBLEM AND RUNS LIKE A TOP.THEN SOMETIMES ITLL JUST SHUT OFF WHILE RUNNIN AND WHEN YOU TURN THE KEY NOTHING AT ALL HAPPENS.

Reset the timing and check starter ot see if working. Verify fuel pump is actually pumping fuel.

You might not believe this, but check your battery. Some of these vehicles have cut-outs when the battery level goes below a preset amount.
I work on Ford brands and on them, a low battery level will even disconnect the Alternator circuit and mess with the starter. Some even act up when the battery slightly dips below 12 volts.

Your antitheft can make your starter cut out. And If you think about it, all of the measurements to make the engine run are based on feedback of voltage and amperage. This is how the engine management system adjusts. If your prime source of power is low, then all of the following electrical readings will be low. Some may be too low to work.

Your fuelpump will hold pressure in a closed system for hours. The fuel pressure regulator will command the fuelpump to stop working if the fuel pressure is at maximum. Without responses from the other components and after satisfactory pressure, the fuelpump will turn off.

you may have a bad starter solenoid.using a test light at the starter the light should be lit on the large wire terminal and with someone trying to start the car yhou should have the light on when the key is turned to the start position.it you have a volt meter you should have battery voltage on the large wire and the same on the small wire when the key is in the start position.you can try tapping the starter when someone tries to start the car.if it starts then replace the starter.its the most common problem.

Used parts such as starters and altinators don't last. It might **** but it sounds like you need to buy a new starter,altinator, and battery. Or just start with buying one at a time.

I was having the same issue with my 95 GMC. I replaced the battery and alternator. It would start fine at times, at other times it would be sluggish. I finally took the starter off and had it checked. Turns out the starter was bad. When it would get hot, it would act as though the battery was dead. Replaced the starter and it has not acted up again. Have the starter checked. Replace if bad.

Are you check your previoud questions: check_engine_error

Keep us updated.

Bad solenoid i would guess. Not making a connection there. Any basic wiring and ignition switch problems should be alleviated by jumping the starter with a screwdriver. I would check the solenoid and starter brushes

OK do the head lights go out then you try to start the engine if yes then its the battery term on battery hot if so dirty fitting (wash with Hot water and spray and refit tight and recheck the lights and starting..
IF auto gearbox then check the Park switch on box it has 3 wires on the side of box.(Under car)
CHECK the Poss + wire on the battery and also the Black earth wire to engine (is it broken off engine as there is also a thin earth wire for battery term to body so the lights will work but the starter takes out a lot of amps and if earth lead isent on engine then it wont turn over.
Check the small wire to the starter motor solinoid as well as a lot are push on terms and have come off if not a tight fit.
So check out all above,,, and let me know how you get on Ron

Try turning the engine crank pulley by hand with a wrench. If it turns freely repost with more info and details on the problem.

Pretty sure the regulator on those is in the computer (I know...really dumb...) There is a way to wire around it using an older style regulator but it will keep the check engine light on and may not pass inspection like that.
