My car is not getting spark from the coil to distributor. Replaced coil with the same result. I have checked and found power to the coil. It ran until I took off and cleaned the MAF sensor. After putting the air filter box back on it would not start. Cranks over fine but no fire. Have also checked all fuses and they are fine. Is it possible I have a loose wire? I have also considered it to be the distributor as I have heard the ignitor wont fire if bad. I have also replaced the ignitor. Any ideas where I go next

Scan for codes and check to see if the duct work from MAF to engine is connected then check for wires disconnected.

Hello PGFASSBENDERPF,

I am sending you a link to an article that features written step by step instructions and pictures explaining how to do the scan yourself, also I have included a link to our YouTube channel with a how to video on code scanning.
This is applicable even if your check engine light is not on.
Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com

Once you have the codes please get back to us so that we can further assist you. We are always happy to help.

Thank you for visiting 2CarPros.com.

All the best,

Also, check fuses and relays under hood like the PGM and main relay if you have those.

Did check all fuses, and relays, all good, did not check the main relay though. Will also do that tomorrow, and again thank-you for your help.

On the diagnostic connector under the driver side dash, jump T1 and E1 pins and turn the ignition switch on with engine off. The check engine light will flash you the codes if there are any stored. OBD1 is not very reliable. If the light just keeps flashing then there is no codes. If the light blinks twice, quick pause then blinks six times then that will be code 26 and then it will pause and blink some other codes if any until it repeats itself.

As for the coil not sparking, you could have a bad distributor? Here is a diagnostic flow chart from the Toyota manual. Follow that chart and that should help you figure out what is going on.

Good luck to you and let us know what you find.

Hello again, checked distributor, NE-G 189. G1-G. 250 AND G2 -G 250, does this mean it is bad since G 1 and G 2 should be between 125-19?

If that is what you are measuring then it looks like the distributor would need replacing.

Yes, I measured the resistance, coil igniter fuses, all comply with specs distributor not so much, but before I throw more money at this, does the 1993 v6 3l have a crank sensor that could be the problem? Could not seem to find an answer on line.

And also, am I correct to believe that a bad distributor can cause no spark from the coil back to the distributor to the plugs?

Yes, you are correct because it does not tell the coil to fire the circuit.

Well I guess I am on my own again, kind of thought that, but thank you guys for trying. I know how it goes, my best guess is the distributor too, guess money talks.

When there is spark issues I always recommend a distributor since they are cheaper now then they were ten years ago. Let us know if the distributor did fix the problem.

Hello to everyone again, I'm back to let everyone know that I figured out the problem on my Camry, turns out it did have to do with the maf sensor in a way. And also my brain fart. I started to think back to what I did exactly when I went to clean the maf and remembered that I started to loosen the 2 philip head screws where the maf plugs into and pulled it out roughly a quarter inch before tightening it back up after realizing no need. Regardless to say and how this affected spark is beyond me but I loosened back up the 2 screws and wiggled the prongs a lil and tightened and it fired right up. I must assume that the prongs were not making a good connection but either way it's purring like a kitten again. I would like to thank all you guys for your input it has definitely been a learning experience and learned a lot along the way. Thanks again
