Help
1984 Gsl - Can anyone tell me how to set the timing on the leading and trailing marks on the crankshaft pulley. Should I put my timing light on L1 for leading and T1 for the trailing? I have a yellow and red mark on the pulley. How do I make the adjustment for the trailing mark ? Is it the red one? How do I adjust it? Is it that important?

First time off of L1 with the yellow mark on the pulley. Make adjustment by turning the distributor. After the leading is done, connect to T1 and see if the pin lines up with the red mark. If not, loosen the two screws on the vacuum pot closest to you. Pushing in will advance, and out will retard the trailing timing. Once done tighten it back up and check it again to make sure it is still lined up. This should be done at idle after the engine has warmed up, ~750 rpm.

No problem. Also check this site if you need further clarification:

This is the FSM for your car. Section 5 deals with the timing and ignition system.

I set the timing for the leading on the Yellow mark no problem, car is running great. I put the timing light connector on T1 and noticed that it was realy off the mark. when I loosened up on the 2 screws the car died. now i can't get it started. After shifting the vacuum post to various positives I am really stumped. Do you have any suggestions?

I have a distributor from a 80 rx but the electrical connections are different. This car was running great except it was hard to start in the morning. i forgot to mention that the idle was about 1000rpm. Do you think there is hope.

Okay, if your idle was at 1000 rpm it is possible that some vacuum advance was being applied. The solenoid with the green connector controls the vacuum advance. Normally, below 1000 to 1200 rpm the solenoid shuts off the vacuum advance and applies the vacuum advance above 1000 to 1200 rpm. Do you remember which direction that you turned the distributor? It is possible that the timing is now retarded if the solenoid was on. I would try to put the trailing pot somewhere near the middle and try advancing the distributor a little (turn clockwise as looking from above) and try again.

If you get it going again, disconnect the green connector. This will disable the vacuum advance. You will still be a little off since you are setting the timing at 1000 rpm instead of 800 rpm, but it should get you close. After the timing is set, reconnect the green conector.

Let me know how it goes.

The green Connector was already disconnected.

The reason the green connector was never hooked up is because I changed engine years ago and the plugs didn't match. Once I get the car running again should I spice the wires together?

You said that the trailing was way off. When you connected the light to T1, was the red mark to the right or left of the pin. Did the distributor rotate at all when you adjusted the trailing? The car should run even if the trailing is disconnected.

Kent

The red mark was to the right of the pin. I never did have the green wire connected because when I changed engines the plugs didn't match.

monad

The distibutor didn't rrotate at all when I adjusted the trailing.

Looking further into your car, the green connector controls the trailing advance and the brown connector does the leading. Are they both disconnected? I forgot that the 12A has separate solenoids for the vacuum advance. The 13B only has one and it controls both the leading and the trailing together. Since the mark was to the right (assuming this is stading directly in front of the engine and looking at it) that your trailing timing was retarded compared to the leading.

So what do I do now

Were both the brown and the green connector disconected or only the green one? Don't worry, we will get this thing figured out.

monad

The brown connector is connected and green disconnected. Since I talked to you I put on another distributor that i had on another motor and it still won't start. I will keep trying.

That is probably why your trailing was so far off after you adjusted the leading. The leading may have had the vacuum advace applied while the trailing didn't. I would have to know more about your setup to be sure. Did you line up the distributor correctly when you exchanged it? Are you still getting spark to all the plugs? Maybe it is flooded.

When you get it going again, try setting the timing with the brown connector disconnected or try to get the idle lower.

I put the pointer on the yellow mark on the crank, dropped the distributor in with the arrow of the rotor pointing toward L1. There is a little circle on the distributor gear and a little pointer on the housing of the distributor. Should I line those up before I drop it in, Or can I just make sure that the rotor is pointing toward L1. I am getting fuel but it seems like i am getting no fire. I will start over in the morning by checking for spark at the plugs. Hope to talk to you tomorrow.

Either way is fine. I usually line up the dot with the arrow before I drop it in. I hope that you get it going tomorrow. Feel free to PM me if you would like. I will do my best to help you get this thing figured out.

Hi kent I am getting No spark to plugs.checked distributor no spark. I thing I may have blown a fuse. What do you think I should check Do you know which one it is? I lost the cover to my fuse box a long time ago.

gsl-se addict

iTrader: (3)

Check the engine fuse. I believe that it is the second one in on the right. I think it is a 20 amp fuse. Is this occuring with the second distributor that you put in or this first? If you have a voltmeter you can check to see if you have power to the coils. That will tell you if it is a fuse or something else. I am assuming that none of the four plugs are getting spark, correct?

Kent

I got the fuse box diagram off of that down loadable shop manual. It is fantastic. I am totally gratful for your help.
I am getting no spark at all anywhere. I will go check the fusing and let you know what happens.

Kent, i checked the positive and negative poles of both coils with my test light. it lit the light but i still feel like i don't know what I am doing. i also checked the 20 amp engine fuse. It was good I am stumped. what do you suggest?

I would put the original distributor back in (if this is the '80 distributor that you are using now). Then try to crank it with one of the coil high tension wire next to the chassis to see if you have spark.

Kent

I check the original distributor for spark before I took it out. I changed from one 84 distributor to another 84 distributor I am not getting any juice to the distributors. I checked for spark at the high tension wires coming off both coils nothing.
