hi all, just fitted another engine off a 6 member off here, mine is a phase 2 engine that has been taken out and a phase 3 one just been put in, fitted everything as it should be, new engine came with an unlocked ecu. after fitting tried to start and just turned over and over, put my ecu back on and it started but popped and farted then revved straight to red line, checked and cleaned all sensors and still no joy. changed TPS, ICV and MAP sensor to mine that i know worked before the swap. anyone got any suggestions? thanks in advance.

now a paid member and posted in the right section.

keeps on revving at red line but i stop it after about 10 seconds, inlet is tight but not sure how tight it should be as it is a PTFE gasket, what i dont get as well is that the unlocked ECU wont start the car but my ECU will that is locked.

all i got was the engine gearbox loom and ecu, no transponder or chip. with the unlocked ecu on the car it does everything it should when turning the ignition on, fuel pump primes the lines, engine turns over but just wont fire up. will have another look tomorrow in daylight. thanks for the help.

got an old manifold gasket off the new engine i could try, i bought the engine off buddagti6 and he told me it was unlocked, so just taking his word for it really. TB gasket is in place but do have a new one i can put on to try. i can only see a total of 3 vacuum hoses that go on the engine, is this correct? one form the brown soleniod near the cam belt cover, one from vacuum pump to inlet manifold and inlet manifold to fuel pressure regulator.

I was going to suggest checking the resonator under the inlet manifold is fitted correctly and not cracked, but good job its sorted

dont have the resonator on any more, have made my own bung and plugged it.
