That old of a vehicle you might want to take the cap off and check to see if the shaft is turning. You will be able to see the rotor turning. Also look inside the cap and see if the rotor and cap are good inside.

You said you changed the ignition coil module, not sure if you mean you changed the coil too, if not change that.

hope this helped

    Your first post said you replaced the icm. Inside the distributor is what is called an ignition module. if that goes bad you get no spark. If you have an Advance near by they can check the module. That would be my next step. Also, just because you put a new coil in does not mean the new coil works. Check the continuity of the coil compared to another one and see if they have the same resistance.

    Hope this helps.

    the resistance of the coils should be near zero comparing one to another wont prove a thing... the problem is in the ignition module itself, within the distributor, underneath the rotor

1989 jeep grand wagoneer 360 how do i test bad crankshaft position sensor

double posted, now with 360, 5.9L V8 fact.
great.
and has no such sensor.
its a CARB car
with ICM , spark magic box. , NO ECU /PCM brain in car
there for no CKP sensors.. sorry?

if you dont know what is there, photo it and post it
so others can see what is missing or wrong, from factory day 1 build.

i google for you
rockauto shows no such part in 360
alldata.com same
hell. even the 90s the same.
see it here.
all schematics

if engine wont start. even with test fuel, check spark
see the spark section below, under ignition.

http://oljeep.com/gw/elec/GW_wiring-1990.html

the distributor has cam sensor. not crank.
it called today, CMP, cam sensor
this sensor sends signals to the ICM the ICM then makes spark
buy driving the coil,
the CMP is more like Points, simulation, and lasts near for ever.

the 89 4L has a CKP (crank sensor) and is know to fail on brand new cars. (you need to tune it to make work , back in 88/89) at flywheel.
ask me how in know./././??


360 spark
CMP >>>>> ICM>>>> COIL>>> Dizzy cap>>> spark plugs.
this is the chain of events.
the DIZZY does the ADVANCING with ICM. totally. on this car.

94 camaro wont start...no firefrom the coil has new icm , coil , fuel pump

Check the icm plug with a led testlight for pulse while the engine is cranking. Test the wire connector with the small wires going into the coil for pulse.The v8 has a opti-spark distributor behind the waterpump that is prone to failure. It has the pickup inside it that tells the icm when to spark. If no pulse at icm distributor is bad. If pulse at icm but not at coil, icm or wiring between icm and coil is bad.The coil also needs pos.+ power on 1 terminal to operate. Be SURE to check the security light on the dash. If VATS [vehicle anti theft system] fails its usually within the 2 wires going from the key chip in the ignition tumbler to the body control module. Mine were purple and tan.Trying to start it with the wrong key can put it in lockout mode also. There are bypass modules available online for vats problems or you can even install a resistor in the wire to bypass the keychip part and the door alarms still work.

Engine turns over getting fuel but wont start. I have an 89 chevy beretta 2.8

Check for spark.If none replace coil then replace spark plugs because continuous startlng w/ no spark loads the plugs with fuel,fouling them.

98 chevy cavalier all of the sudden car wont start,

Well I don't know where the computer is. For most vehicles they are found under the car deck area. But if ur not getting spark, that is usually due to the distributor. That is where the spark comes from. Look into that area. Distributor might be faulty
