what have i done?

[weazgti]

Just pulled the ecu out to check the connecter were ok and all seemed fine. so i put it all back in and now it wont start. The fuel pump primes and stops as normal but as soon as i go to start it the relay goes nuts.
Any suggestions to whats gone wrong?

broken it 

have a search, but i am sure if you dont do things in a correct way you can fudge the ECU

Hi
Was it the 16 pin connector ?
Was the ignition ON when you unplugged/plugged it ?
Are you sure it is seated tight ?

[weazgti]

yes the huge one. ignition was off at the time and all i did was unplug everythin,check for corrosion and plugged it all back in.
Fuel pump primes and goes off but the relay for it clicks like mad.

.......and all i did was unplug everythin,

Hi
What else did you unplug. ?
Relay clicking like mad can also be a low battery. Charge the battery.

[Khare]

was the battery disconnected when you unplugged the ECU? Please say yes.

[weazgti]

No...it was connected.Thought it only mattered trying to start with no earth which i didnt do. why would that matter then?
mattkh.... i unplugged the tci plug and whatever the other plug on the front is aswell as the huge connecter.

As far as I'm aware the ECU has a permanent live, I may be wrong though. The ECU is very sensitive (female) so any voltage too high and it will fry it.

[Mr Blue]

Did you connect the ignition moduel back up? it sits ontop of the ecu.

I believe Khare is spot on and you have fried the ecu.
