I would check ignition coil. Maybe it is outside or inside the distributor.Check rsistance. Get ohm values from a haynes/chilton repair manual(i do not know them)NOTE DISCONNECT BATTERY to check resistance. check condenser(capacitor)inside or close to distributor.

1992 isuzu rodeo has no spark I have changed the coil , the rotor , the spark control modual , the ecm , the pick up coil , still no spark could it be the ecm relay ??


double posted, why?
I guess you are h3ll bent on gue$$ and not testing.
so keep going replace everything, we love to watch.
why not use the diagnostic jumper as posted in your other posting.
why>?
no spark out of coil right.
recap of last answers.
fuses, good, all 7 for ecu +spark good????????
we test them not guess, but ones that look blown are.
CEL Glow key on,?
flash codes ok 5 seconds cranked.
CKP good , the ECU will tell you its bad with flash codes.
why skip this key test??????????????????????????

The ECU must have power ! this is first. not changing out tons of stuff, 12vdc power,, and there are 7 fuses.
i bet you never tested them
or measure all ecu power pins to see if its has power first.
and is FIRST, no brain,(ecu)no spark and then no fueling.
if the CKP is dead, there can be nos spark.
ever.
I can only presume you connected a good new spark plug
to the actual coil tower point, then ground the spark shell.
and cranked and spark really is dead, 100 years, same way.
if dead, check 7 fuses.... seen in the book on car.
log in to mitchells diy. (google that)
and read how it works, its all there, read it.
a schematic to.

Ignition not firing


Do you have fuel, is your fuel pump working. If you do not have any spark at all, have you been able to check to see if you have power to your distributor. If so and you do have some then it might be either your ignition coil, pick up coil or your ignition control module. Your pick up coil in in your distributor under the plate. The coil is on top of the distributor cap. The ignition module is right under the cap where all your distributor wires connect to. Some part houses can test your ignition module and let you know if good or bad. Good luck.

1989 GMC engine turns great , no spark at coil or plugs, had coil tested and repalced- new rotor and cap. not sure where to go next


Check your fuses (ECM) and also recheck your wire leads to the coil. Your ICM (ignition control Module) may also be bad, it's located in your distributor under the rotor. You can have that tested also to make sure it's working 100%, there common to go bad from corrosion caused by condensation under the distributor cap.
Thank you for using Fixya and good luck.

Truck wont start. battery test good.truck cranks over,but drags down after a couple of tries,has new starter and spark plugs, truck has good fire from coil but weak fire to the plugs could it be a moduale...


drags down and then clicks? then is a dirty batterie post if that is not it, then there is a fuel problem to check, starting fluid spray through the intake air, make sure not to spray directly onto the map sensor.

Van will not start I have fuel pressure and when cranking it builds oil pressure where do i go from here


Check for spark at the spark plugs. If no spark, remove distributor cap and inspect the inside of the cap and the rotor for obvious signs of wear or damage. Check for spark at the coil wire by removing the coil wire from the center of the distibutor cap, and, holding the end of it close to the engine block, have someone crank the engine. There should be a very strong spark. If there was spark at the coil but not at the plugs, replace the distributor cap and rotor. If there is no spark at the coil, you either have no power or ground at the coil, or the coil is bad. With the ignition ON, there should be 12v at the red wire for the ignition coil. if not, check the fuses. Check for the pulsing ground signal of the ignition coil at the other wire ( I think a white wire) using a test light clipped to battery + while the engine is being cranked. If there is no light, the problem is likely the ignition module or pick-up coil, which is located in the distributor. Make sure that the wiring and connections are in good shape for these items before condemning them.
Pick-up coil should have about 1500 ω of resistance.
Good Luck
