Topic: Electrical issue, need help

[jafish]

First off, it's an 85 with a 22R.

When my buddy picked up my Toyota, it didn't run, the previous owner said it needed a new coil. After replacing the coil, it still wouldn't run, so he took it to a friend's shop/junkyard and they worked on it for a while. What they eventually found was that the gear on the crank or cam (can't remember which one) that works the distributor was broken, and the distributor wasn't turning. So, they tore apart the front of the motor, and fixed it, however, it still wouldn’t run. My buddy stopped at a Toyota dealer and was told to check the ignitor, which costs a whopping $390. So, with that in mind, they went to work again and found that the ignitor was bad, so my buddy found a 2 in his friend's junkyard and bought them for $20 a piece. Once they replaced the ignitor, it ran great. My buddy drove around the junkyard, climbed on top of a car, screwed around for a while and then drove it home, 45 minutes. It ran great. The next day, he went to move it in the drive, and it wouldn't start. So, he replaced the ignitor with the last one we had, and it started right up, unfortunately, it only ran for about 2 minutes, and died again (appearantly the ignitor blew again). Out of frustration, we decided to go with a GM conversion that I found on Pirate ( http://www.pirate4x4.com/forum/showthread.php?t=179253 ), but I'm afraid that it doesn't work (even in the thread, several people said the conversion doesn’t work). We followed the instructions to the "t", but it doesn't work, period. Now, speaking to other Toyota wheelers, several say that they have 300,000 miles on the original ignitor, with no problems. So, it seems to me that there has to be a very logical explanation as to why mine keeps blowing the ignitor. So, what is the problem, a bad ground somewhere? Why would it run for an hour plus on the one, but only 2 minutes on the other? Somebody needs to tell me what the hell is up, I'm so freakin' frustrated!!!!!!! PLEASE HELP!!!

There has to be a simple answer, however without being ther and looking at it, it is hard to tell what could be the problem. Post a link to the thread where you got the info on the conversion so we can look it over.

Heat has an effect on electronics and if you went through two used ones it could be they were just bad to start with, but before you spend $$$ for a new one you need to know if there is something wrong to cause this to happen.

Do you have a wiring diagram you could use to check all the wiring to make sure it isn't miss wired?

Or maybee some sort of short.

The link to the GM conversion is in my first post. As for a diagram, no I don't have one. My biggest problem is probably that I know very little about wiring.

There are 3 wires that run over your exhaust manifold and valve cover they are in a plastic sheath or should be they connect to your igniter. They can burn or crack and tuck each other. unwrap them and check them. I needed to replace mine because they cracked so i made it longer to follow the vacuum line to my brake booster and then plug in, keeping it away from the hot stuff  good Luke
