I don't remember if the engine will spin over without the ECU in place, but if it will you can always do a compression check while waiting for the ECU.
I haven’t sent the ECU off yet. Noid test kit will be here today. I actually ended up sending the fuel injectors off to get cleaned to ensure they are 100%. I should get the fuel injectors back by the end of the week. Waiting to hear back if they found anything.I don't remember if the engine will spin over without the ECU in place, but if it will you can always do a compression check while waiting for the ECU.
