If you replaced the ecm you should have transferred your prom from the original.

Sorry for the delay Steve. Did you sort this out?

It is possible you installed the chip backwards.

It is also possible the new ECM is bad.

What was the reason for replacing the ECM in the first place?

The prom was bad. They rebuild them now. Narrowed the problem down. It appears that when my son replaced the oil pressure sending unit he only got 1 prong in the plug.
Don't have time this weekend so will fix it Monday.

I have a 2 day trap tournament Sat and Sunday

Hope this is the answer to no start

Steve
