Hey Guys,

I have an 84 GSL-SE with a good deal of stuff done but stock ignition.

A couple of weeks ago I drove the car about an hour to our test track then shut it off. I got back in five minutes later and it wouldn't start. Fast forward half and hour, it started, ran for about five minutes then died. Fast forward two hours, the car preforms well with only some break up on track.

I drive the car an hour home. I turn it off, get back in half an hour later and it makes it half a mile then dies. As I am looking over it I see that the Accel coil is leaking. I switch the wiring over so it runs on just the leading. I get home again and the car will not restart.

I leave it in the garage for two weeks and now I can't get it to start. I changed out the Accel to a stock Diamond coil and there is no leading spark. I put in another coil and still nothing. I change out the leading ignitor, still nothing. I am getting spark to the coil but none to the plugs. The car will not even run off of the trailing wires wired to the leading plugs.

I am running out of ideas. The coil pick up in the distributor? I am not familiar with this part. Any pictures?

Thanks in advance for the help.

What does the cap look like? The rotor?

Are you actually getting power to the coils? Are you getting power to the ignitors?

How did you get it to run on just the leading ignitor?

The Se needs the trailing ignitor to activate the fuel pump.

Are you still running the injection system?

Still running the stock fuel injection. I am trying to get it running again before swithching over to megasquirt.

I am getting spark to both coils. Or at least both over them will jump the gap when I pull the wire. I am just not getting spark to the leading plugs.

Rx-7 Doctor. I just switched the wiring of the coils around and it got me home.

I know what the cap, rotor etc look like. I was unfamiliar with what exactly the pickup coil looks like.

I think I found the problem though. The metal piece on the pick up coil seems to be gone comparing it to the one on my spare car. Should I just switch distributors or pull it apart and replace the pick up coils. How can I make sure I don't screw up the timing when changing the either the internals or the distributor.

Thanks

Well that didn't help. Still no spark.

Does spark control run through the ECU at all?

If you are getting spark to the trailing plugs but not the leading then you have a bad ignitor.

I changed out the ignitors with no affect.

Update on it. I put a extra plug in each wire and cranked it. THere was spark on from all four but it appeared to be weak. It will spark on the plug but will not bridge a gap to the chassis.

It tried to start last night. I really didn't change anything out but it would start for second then die. It appeared to be getting good spark from all four wires. It did this twice and then just cranked like before. The battery was getting weak and I couldn't get a jump on it until this morning. I figured I would get a jump on it in the morning drive it around then start on the MS install.

I get a jump on it this morning and again it has weak spark. I didn't change anything so I am out of ideas. It wont push start not that I really expected it to.

I do have one question. Which is the leading coil and which is the trailing? According to the FSM the leading coil is the one closest to the headlight. This is contrary to what I have read on the forum.

Thanks for the help. I am ready to set the damn thing on fire.

The trailing is closest to the headlight. This is because the trailing's coil wire goes into the cap closer to the radiator than the leading. (The coil wires do not have to cross each other to get to the cap)

The trailing coil should also have a blue cap over the positive stud, the leading has a black cap.

Thats what I had always thought. I wonder why the FSM reads differently. Either way I hook it up it won't run.

I tried jumpering the fuel pump and could hear the relay click but couldn't hear the fuel pump. I really doubt it a fuel issue anyhow.

I am pretty much out of ideas. I swapped over ECU's from my other car and have changed or checked everything I can think of. Maybe a wire in the harness has broken off or is shorting?
