Okay new trigger is in. Spark on all cylinders. But it cranks and doesn't start. Made sure battery was fully charged but it dropped from 100% to 50% after trying to start once. Is this indicting a battery that needs replaced?

I think I've discovered the problem... hopefully.. I discovered today that the "spark advance of the trigger was not moving underneath the flywheel when the throttle was moved. I'm thinking either my spark advance screw or primary pickup screw cam loose at some point and threw off the timing...

Re did the wiring and harness from the trigger and still having the same problems.

The corrosion goes a lot further down the wire than I originally expected. I got heat shrink tubing and will be repairing the wires today.

Okay, I will give that a go. What would be our next step if that doesn't solve our problems? Want to have my flow chart ready! lol

Also is an inline spark tester be sufficient or should I be using a proper spark plug gap tester? This is what I have.

I didn't take a picture but I will take one tomorrow and post it. I think they're all connected so I dont think thats it but I would still like to repair if possible. If thats not it I'm thinking the control module maybe?!

A bird almost pooped on my head today but it hit the flywheel cover instead, and then some scorched wires caught my eye... the wires coming from the trigger assembly are very corroded just before the harness. 1) could this be causing my problems? 2) Can I repair the wires or will I need to...

Yes. From the looks of the spark plugs. 3 & 2 don't seem to be firing at all. These spark plugs were just replaced and engine has only been run during testing since.

Also I am going based off of the numbers on the CDMs port side 2-4-6 top to bottom and starboard 1-3-5 top to bottom. Compression seems normal 1- 120psi 3-110psi 5-115psi 2- 110psi 4-115psi 6-120psi

Plugs from left to right 1-3-5-2-4-6 Cylinder 3 doesn't even appear to have any fuel on it...

Okay... Is it possible it's only running on 2 cylinders. I got my inline spark tester today and it only lights up on cylinders 4&5.

It's smooth. Just feels like I'm at half throttle instead of full throttle. I ordered a spark plug tester and a compression tester. I also have a port side temperature sensor on order just to rule it out. Will report back.

Wow, im a dummy. 2000 Challenger 2000 with 240hp Mercury M2. I don't have the exact serial number on hand but I looked at it yesterday and the corresponding build on Mercury Parts Catalog was 0E373939 thru 0E384499. Thanks in advance Dr Honda, couldn't figure out how to tag you but was hoping...
