ok i have an 89 pickup v6 3.0l 5spd 4x4. ow it cranks perfect. i just changed the timing belt and everything is in time, but it wont start. im getting fuel but no spark. any suggestion? aslo was wondering what the cmh relay was.
But proper diagnosis would probably cost a lot less. And will likely be qicker too.
I've been working on toyotas for over twenty years and I have only ever seen 2 bad ignitors on trucks. One had a shorted coil that took it out, and the other was jump started backwards.
First, check for trouble codes.
Then check to see if you have battery voltage at the coil with the key turned on. If you don't trace the fault to find out why. If you do check to see if a test light pulses during cranking if it is connected to the coil negative terminal. if it does, you may have a bad coil, if not you should have found a code earlier.
code 14 is your big clue, It indicates there is no IGF signal from the igniter. IGF is the ignition confirmation signal. It tells the ECM if the spark happened. If the ECM does not get this signal for 6 consecutive revolutions it shuts down the injectors to prevent flooding the engine real bad.
Unfortunately I do not have the specific diagnostic information availale to me at home. If I can remember I will check tomorrow at work.
You may have a bad igniter, but if it ran before you worked on it I would say it is more likely to be something else.
Go back and make sure you did not leave anything disconnected.
after reading up a lil bit and lookin i dont even have an ignitor. never was there when i got it. i got it not running. i put the timing belt on and got it back together. when i went to turn it ove it wouldnt start so i thought no fuel and sprayed starter fluid in it and nothin so it ment no spark. thats when i posted this thread and found out about the ignitor. and its not there my buddie is givin sellin me one for real cheap so i will let you know what happens.
if it still has no spark any suggestions?
