Hey'all. My truck died the other day, so I tested some components and the ignition coil was bad. Replaced that, and the only way now I've been able to get it to run is to crank down the distributor so that it's 20-25 degrees BTDC. Otherwise, it won't start, and if I switch it to say 10 deg, it bogs down when I hit the gas. I check the vacuum advance, no problem there. Blew a bunch of carb cleaner through the carb (thought maybe a jet was stuck). Looked at the timing belt, thinking that may have slipped, but the crank and camshafts were in line and there was no noticeable wear on the belt. What the hell is going on here? I thought for sure it was a distributor issue, given that it would work but only at such a crazy advance. Then I thought the carb, but I can't find anything wrong with it. Help would be incredibly appreciated!!!

 

I'm far from an expert on timing, but that sounds similar to a problem me and my bro had timing a Mazda. It turned out the distributed was a tooth off when we put it in so we had to correct it. BTW, it ran fine but wouldn't pass smog before the timing was fixed.

 

I'm really confused....Carb...timing belt...those don't go together lol

Did you remove the distributor for some reason? Other wise it sounds like you have a timing belt issue. I'm guessing its the 3VZ...need some more info

 

i'm assuming this is a 22r with the vac advance

if that's the case, x2 on distributor off a tooth

 

OR, if it's the 3vze, you need to jumper the terminals before you set the timing....

 

if its the 3vze are you sure your not on #2 on the drivers side, im pretty sure #1 in in the front passenger side of the motor might be that what engine do you have?

 

if he's got vacuum lines on the distributor it can only be a carb'd 22r or carb'd 20r. if the distributor is off a tooth he wouldn't be able to get timing advance he has on it like he does. The only thing it being off a tooth affects is the range of which you can get the timing. meaning if it's off a tooth you will never be able to time it to 0 degrees where it should be. Sounds like he's already tried at 0 degrees and it won't run.

Now if the timing chain happened to jump a tooth that's a different story.

Which leads me to the next question, where was timing at before he changed it to advance it when it started not to run.

 

Well hes not really responding, it would be great to learn what engine he has and if and why he touched the dizzy
