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

Post by tonawawa »

I am trying to get my 88 Mustang, with fresh Dart 363, AOD, and MSPNP2 to run.
I have the stock map disconnected, should I keep it plugged into the factory harness?
My MSD 6AL2 is hooked up with the MSD harness and connected as instructions describe, anything else needed here?
The fuel pump turns on, and I have 40lbs at the fuel rail.
It will fire but will not start.

1. Doesn't matter, it's not connected internally to the MSPNP2 which has it's own MAP.
2. Assume you mean the MSPNP is now controlling it?
3. Probably not a fuel problem.
4. You probably have to modify the MSPNP2 tune to your setup, i.e. larger injectors.

I am going to try and re-stab the distributor today at 10-BTDC instead of at 0TDC. I am also charging the battery, it was getting a little low.
It almost wants to run. The MSPNP2 req fuel is set to my engine size/ inj size, sensors are calibrated.
Thank you for the help.

Do you know where the spark timing is set? Changing it if it is set right will be a step backwards. I believe a TFI has a 10° cranking mode built in. Do you have a steady rpm reading in TS? Are the sync lights in TS showing synced?

I set the timing to 0TDC, without the light, for my base timing. The green light shows sync only when I try to crank it over in TS. I believe I get 3green boxes down there.

0 degrees is about 10° late for base timing. There are provisions for attaching files to your posts in the forum.

Set base timing at 10BTDC- still noting.

What does trigger wizard do? It shows a number but is that my actual timing? What is the timing number good for in the trigger wizard?

Sounds like you need to do some reading of the manuals.
Have you checked your timing with a timing light during cranking?

I have read, the manual did not say what the number is. I haven't timed it with a light.

Have you made sure the MSD has a 12v supply in both crank and run key positions? I have been bitten by that one before.

Yes, MSD is hooked up correctly, heavy red to battery.

I would be surprised if the manual doesn't explain the trigger wizard.
The trigger wizard helps you get your trigger angle set up correctly, but you need to do this with a timing light.

You really can't just assume anything with these setups. Put a timing light on the car while it's cranking to make sure the spark is actually where you expect it to be.

If the small red gets power in crank but not in run you won't get any spark when you stop cranking. Easy thing to check.

The MSD is hooked up with the MSD harness, small red wire is in there.
I set the base timing 10-BTDC, it looks right, with the distributor cap off. I need a second guy to time with a light.

Then do it with a second guy. Assuming this stuff is right without actually checking properly is a sure fire way to either damage your engine or at the very least, have a setup that does not work as expected.
