They left it sit for a few months, then ended up moving. I bought it from them. When I got it home, I found one of the right side cylinders full of antifreeze.
I pulled the engine, replaced the head gasket again and reassembled. I think the antifreeze came in through the intake manifold.
Anyway, I've got it together but, can't get it to fire. I thought it might have been my ECU. I put the ECU from my runner (another 88 GL) and it still won't fire. My runner started up with the ECU from the dead GL.
Hey, General Disorder, how do you change out the ignition module? Is that the wire coming off the disty?

is the body cabled to the negative batt post?
just a thought

I did learn a little bit about the ignition systems on the SPFI cars, so I'll share with you.
These cars use an optical pickup, crank-angle sensing distributor. The spark advance is controlled by the fuel injection computer. There is a very small igniter module built into the coil mounting bracket.
So, if you're not getting spark, it must be a problem with either the coil, the igniter, the distributor, the computer, or the wires in between them.
I'd suspect the igniter or the coil at this point. You should also check that you have 12V at the + terminal of the coil when the key is on. If not, try jumpering power to it and see if it runs.

see if you get spark at the coil

and the igniter, is sometimes off the bracket and down a wire a few inches, that could be it too. you gotta be able to hotwire the coil right guys?

The timing marks are 180 from each other. I lined up on the center of the three hash marks, positioned left cam at 0 deg., rotated engine one revolution, lined up on the three hash marks again and set the right cam sprocket at 0 deg.
Is there a wiring diagram I can get online? I think I need to ring out a few wires.

There is a fuse on the fuse panel controling the positive voltage to the coil. Might check that IF you are not getting the battery voltage on the + coil terminal
(I mentioned this is a previous no spark post but it was kind of after the fact)
The power transistor (amplifier) on the coil bracket is NOT an ignitor (They are found in some distributors and feed info INTO the spark control circuitry, the ignition amplifier - amplifies the signal AFTER the circuitry -whatever.
