ECU problems

[chriso]

Hi can anyone help me i have recently took the ecu out of my car to get it chiped. i i have left the ecu out of my car for around 2 weeks wile this is being done i have brought another williams ecu exactly the same to use in the mean time all the part number`s match. I went to plug this ecu into my car today and nothing happens the starter turns over but the engine wont fire. i am really stuck with this and have no idea what it could be now i have read some posts on this forum about williams ecu`s not being coded to the imobiliser does any 1 no if this is defo correct. I also removed 1 of the spark plugs to check if there was a spark nothing happend. The car started fine before i removed this ecu for 2 weeks no problems at all is it posable that the ecu could lose settings ? i dont think its the imobiliser because i dont think the starter motor would crank if the car was imobilised please help if posable :roll

any williams ecu will run in a williams.

Pn2 Valvers will work with ph1 ecus, but not the otherway around

If it was imobiliser problems ur right the engine would crank over but as soon as pedal touched it would die...
