Mustang mspnp2, msd 6al2, no start- but fires

Sounds like there's quite a few basics to sort out here before you re-connect the Megasquirt.

Pull the plugs so the engine can turn over freely.
Charge the battery.
Check all power cables between battery, engine, chassis, starter motor etc.

ok.
Is it possible to set timing with the plugs pulled?

Yes. But first the TFI module needs to actually be powered and working.

Still no spark. I believe the MSPNP2 is defective. Just tried my first MSD distributor that I sent to MSD to get checked out. They put new parts in it and tested the electronics.
It cant be any other thing! No signal from Megasquirt.

As previously discussed, TFI ignition is designed to be able to work without ECU control (for limp home or testing) - unless MSD broke that feature perhaps?

You've also previously said that you have the SPOUT jumper unplugged.

Have you performed the standalone tests that I've previously suggested?

I have the MSD box disconnected, I am only using the MSD distributor. The TFI does connect to the computer, how can you run by disconnecting the TFI?

TFI can run the ignition on its own. YOU MUST TEST THIS.

If it doesn't fire the ignition on its own, then it is broken. That's why I've been telling you to test this for days.

The TFI has been tested at Autozone and at MSD Headquarters.
How do you suggest I test it? unplug the computer and try to get spark???

Yes, that's what I was suggesting last week.

This has been said before, but I will say it again.
The TFI will work without the ECU even being there. Even if the MS was broken, the TFI should work in "limp mode" where it will give a 10 degree spark.

So unless you can get spark from the TFI when MS isn't connected, you need to find out why.

No spark with MS disconnected.
What should I check now?

You're definitely using TFI?
Can you post pictures of your setup? Distributor, TFI module and anything else related?

tonawawa · Post by **tonawawa** » Mon Jan 11, 2016 8:06 pm

Yes it is a Ford TFI ignition. Not sure how to send pictures but it is a MSD distributor.

You sure your coil isn't stuffed?

tonawawa · Post by **tonawawa** » Mon Jan 11, 2016 8:16 pm

I have 3 different coils, stock, new accel, and a brand spanking new performance one today. Same with all 3.

What do I do now? Does anybody have any ideas?

Thank you, Chris

Are the distributor and coil getting 12v during cranking?

James

Post by **jsmcortina** » Tue Jan 12, 2016 3:48 am

Do you have the TFI and coil wired up as shown in the manual?

Ton, you need knowledgable help.
After 6 pages of posts that is clear
Where are you located? Maybe someone can stop by and give you a hand.
