Question about Jeep Grand Cherokee
We cant help at all , until you disclose the engine option.
what engine, of the many?
1: check all fuses.
2: do the skipped ? 60k mile tune up now.
3: if engines has EGR clean it , now the main valve must not stick.
4: clean the ISC valve.
did you for get filters at the 60k tune?
so it wont start ,so do you have spark at all 6 or more spark plugs.?
that be First., (the PCM cuts fuel if spark is lost) so........
when it fails to start we check for spark and also
connect the Diagnostic jumper, and see the CEL flash
and see if we get DTC errors cranking. (5 sec. crank minimum)
if you get these errors, BINGO, no more wasted money replacing senors. the PCM reports a bad CKP sensor fast.
see ZJ here.
also watch the ASD relay ,
does it close at key on and stay closed for 2 seconds.
and if you key on and crank fast, does the ASD stay closed
for full cranking duration?
no, the PCM sees errors and drops the ASD by DESIGN. (fire safety)
learn how your ASD works.,
did you replace the whole distributor and not read the FSM
on HOW TO DO IT? oops..... now its 2 times busted.

yes checked fuel pressure and replaced the fuel filter, checked the mapp sensor,tested throttle position sensor, has strong spark, 50psi fuel pressure, fresh tune up, runs real rich and rough idle but wont rev up like fuel injectors arent speeding up, also checked exhaust. thanks julius

listen for a vaccum leak.also try disconecting bat for 5 min the reconnect and start truck and hold idle at 1500-2000 for 5 min. this resets and teaches computer to self adjust

If you have a GTP these engines use a hi output fuel pump. they use a fuel pump resistor located under the battery tray (look up from under the car) This resistor lowers the voltage to the fuel fump when not in boost mode. because of its locatoin it is prone to corrosion. if you bypass the wires and the engine starts and stays running replace the resistor
