no spark?

There is more to the distributor more then coil and ignitors try another distributor

my car was running well , after one right turn, it suddenly stopped.

I ask someone to check it, found it is no spark.

what should I do?

Check for a bad crank sensor or coil.

this corolla is AE102ef model.
the engine is 7A-ef, 1726 ml.

I check the car, did not find the CPS.

this car, the coil and distributor are together.

there is a diagnostic box located next to left hand side shocky.

this car, when I turned the key on the check engine is not on,
is it possible the ecu problem? the fuse and relay is OK.

I checked the fuse box, found AM2 30A fuse is blown.
I pulled fan fuse to replace it.
the check engine light is back and car started.

Electrical problem
1992 Toyota Corolla 4 cyl 191000 miles

I have replaced the distirbutor, plugs, wires, ECU, cap and rotor. Car turns over but no spark. Could it be the igniton? Rotor turns, so I assume it is not the timing belt. Sorry I am a broke college student.

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

If you have replaced the distributor and ignitor, check relays in main relay box under hood.

I have checked all fuses and relays (that I could find).

Not sure if the Corolla's had it back then but there's fuses inside the cab passenger side left knee area in some of the newer models.

There is a kick panel inside car near left foot.

I would check, but most likely the problem is in engine fuse block. Look at "engine main" relay.

I found that the new rotor I had purchased had a hole in it. I thank you guys for your help.

Glad to hear it.

Hi Im stranded outside my school right now, trying to get my horolla to FIRE. First of all, im go to school to be an automotive tech. After school, i did a cylinder compression test; removed all4 plugs and set aside the wires( i didnt disable the ignition like i should have, just put the plug boots aside pointing up in the air. Tested good, 170 psi per cylinder, OK, so i put back the plugs and wires AND IT HASNT FIRED SINCE, Ive been working on it for 2 hours.
l.The rotor spins like it should.
2.Its getting Fuel.
3.All fuses are ok.
Is it possible that i blew something by not disabling the ignition while cranking? what could have blown? Im ready to go home yall! but first i have to get her running!!! Thanks in advance for any ideas.(92 toyota corolla 4AFE, auto)

You need to check for spark-what made you checked the compression

Right on. i just bought the car last week, so i compression tested and vacuum tested it

...and now im gonna check for spark. thanks

It may just be flooded, as the injectors will still spray fuel while the comp rest is being done, worth checking if you still got spark.

Ignition system problem, won't start. Does this model & make have a history of bad distributor

Most likely a bad ignitor. Actually the 90-92 Corolla are one of the most dependable they made.

The only problem they had was the exhaust manifold cracking due to a bad shield design. This was recalled and replaced with a shield that has slits cut into it for better heat dissapation.

1990 corolla with no spark. good coil good pick-up coil, power to the igniter with ignition on. could it be a bad fuel injection relay ?

Double check the Ignitor the fuel injector relay has nothing to do with spark then again it doesn't exist.

IS THERE A way to ohm the ignitor for resistance. Could this be a grounding problem.

Might also be the Igt and Igf circuits or the computer itself. Test the distributor pick-up coil resistances before you do above.

I have no spark. Replaced ignition switch, 2 different ecu's and 2 different distributor assmblies. Ignition coil is also new Every thing ohms out fine. Checked wiring for obvious problems. Car ran good a couple weeks ago but died and now have no spark. I noticed that the "check engine light" is not on during cranking or with the key in the on position. I also was checking the relays and noticed that the Main Engine Relay and the Efi/f/htr relay pulling in when you turn the key on but don't disengage when the key is turned off. This doesn't seem right. This is got we going nuts as I desperately need this car back on the road asap.
Thanks

You must have a shorted or open connection between the distributor and ECU here is a guide and the ignition system wiring diagrams so you can do some testing.

Check out the diagrams (Below). Please let us know what you find.

Cheers

Thanks for the guide and diagram I found the black wire not connecting so I ran a new wire and it fired right up ! ya! I love this site

Glad you could get it fixed, that kind of problem can be tough. Please use 2CarPros anytime we are here to help

Cheers

I have gotten new plugs wires and distributor. it tries to turn over but there is no spark coming out of it at all.

Can you give me a little more detail about where you are not getting spark? Clearly it is not getting to the plugs but when you say it is not come out at all, do you mean it is not coming out of the distributor? If not, take a look at the wiring diagram and we need to track the spark back through the coil and igniter. I have seen a number of Toyota's that have an issue with the igniter so we need to find where we have voltage and where we do not in this system and that will tell us where the issue is.

Let me know what you find and we can go from there.

Hello I have a 1989 corolla sr5 309,000 miles. I will start at the beginning of the problems. Was about to drive to MI from TN, was on the interstate for thirty minutes and the car started overheating. I let it cool and added a little water i had to it. On the drive back home the temp was still higher than normal around 75-85% of gauge but was not overheating. Parked the car for two hours decided I needed a new thermostat and a coolant flush because of how rusty the coolant was. drove the car 20 minutes to auto store, car was operating normally, not running hot was at normal temp. Flushed the coolant system and replaced thermostat later that evening, started the car everything was fine temperature was normal, car ran for approx. 10-15 minutes windows starting fogging up because of the humid weather so i turned ac on and within 10-15 seconds the car idled down and stalled. then the car would not start back up. turned ac off still not starting. it is getting fuel, no spark though. Please help

start with basics. with the mileage, do a compression test. if the timing belt failed, it would not have spark.

if it does have compression, it may have a bad rotor or cap and further, the distributor may have failed.

Roy

I have inspected the rotor and cap both look like they are in good shape, could it be the coil? I checked voltage at the connector that runs wires to the coil and it was showing 12.4 volts with the key turned on, not cranking. not sure if this helps or if its relevant..
Thank you for your help!

did you check the compression???

12 volts to the coil on the plus side. the negative should pulsate a test light while cranking. if it does, most likely a bad coil . if it does not, then it is a control issue

Roy

I have not checked the compression as of now because i dont have a compression test tool, also I dont have a test light just a volt meter. Thank you again for your help I am desperate to get this fixed!

I have checked all fuses, unplugged and plugged back in all relays. I will check to see if camshaft is turning when being cranked as soon as I have an extra hand. Thank you again for your help Roy. Any other suggestions would be greatly appreciated. Phil

Think, Ignitor too! after you check the distributor pick-up coil resistances-without the Ne- and G signals the computer will not tell the ignitor to fire the coil if it doesn't get the Igt signal

Thanks for everyones help! Turned out to be a bad coil. The coil showed 9.34 for resistance vs. the new one at 11.7. Thanks again
