Standard 34 Gtr Ecu Not Starting?

[ricknismo]

I haven't gotton around to getting my Power FC tuned yet and as I read that the standard computer has probably a 'quicker' tune I decided to put it back in.

The Power FC has only been in about 2 months and nothing has changed since I took the standard one out.

All it does is wind over but not start.

When I put the FC back in, it starts firts time.

It will be a few months before I can get the FC tuned, why would my standardy not start?

Its just a regular PFC im assuming, not DJetro.

Do the diagnostics work?

this is the original ECU meant for (and came with) this car?

I dare say the factory immobiliser is playing silly buggers with you. my understanding of a PFC is that it does not have this option inbuilt so the car will run fine.

Normal FC.

yeah actually the immobiliser sounds logical, maybe a full disconnect of batter and let discharge might be the go.
