problems timing the dizzy


Recommended Posts

I am having trouble timing an engine I just finished installing in my 1990 loyale. It is an ea82t but the engine I beleive is newer than that. I cant get the distributor timed right. I have heard that it should be timed 20 degrees behind tdc. I lined it up with the 20 on the flywheel, marked the first cylinder wire and lined the dizzy rotor up with the mark and put it back together and I only get a couple little cylinders fires here and there. I had it running very rough for a second when I was fitteling around with it. Was my timing procedure correct and if do what should I go after next

The timing sould be set to 20 degrees before TDC.

 

What you need to do is possition #1 TDC and Insert the distributor with the rotor pointed to #1 position. Plug the two test mode connectors together and start the engine and let it warm up. Then set the timming to 20 degrees before TDC.

What are the test mode connectors? I originally timed it at the zero mark on the fly wheel, this is tdc right? So is the 20 mark 20 degrees before tdc?

The test mode connectors are two little green connectors that are usually located near the firewall behind the driver's side strut. However, I think on the turbo models, they're under the steering column. When they're plugged together, the dynamic timing advance is set to 0, so that you can set the static timing with a timing light.

 

Stab the disty as described above, set the timing adjustment to the middle of its range, plug in the connectors, and crank it. If it fires, set the timing using a light. If it doesn't fire, adjust the timing back and fourth until it does. You may also have to move the disty a tooth forward or back (I've rarely gotten it right on the first try).
