I got a 1.2 16v elx mk2 i have a problem tho car starts then dies immediately took it to a auto electrics and he said my ecu is f****d could I buy a second hand one 1.2 16v exactly the same with the locks fuse boards and keys and put them all in, will i need to reprogram the ecu or is it the case of plug in and it will start. thanks for any replies

what ecu is it?

That is the ecu im using

What were the error codes? The 16v ECU's aren't commonly known for failure.

Error codes were misfire I had replaced coil pack ht leads spark plugs crank shaft sensor only thing i can think of is the ecu so I was wondering if i replaced the ecu with the locks and keys for another set of the same car will it work or will I need it programmed thanks

Misfire on specific cylinders, or "generic"?

There's numerous causes for misfires, besides ignition-related:

Evap. control valve stuck open (over-rich mixture)
Unidentified lambda issues running it too lean
Fuelling problems (injectors, weak/bad fuel, low fuel pressure, etc)
Mechanical issues (compressions, damaged valve/s, cam timing)
Etc
Etc

I would not condemn an ECU on a "misfire" error code.

Thats the thing see i had it checked over by a mechanic he replacd all the senors still nothing he said he checked everything it got to be electrical and the auto electrical man said its the ecu

Get the ECU inspected/rebuilt if faulty? Will save you having to faff about with locks, etc.

Every single sensor on the car? A mechanic who simply replaces sensors on a whim is an idiot- I hope you didn't have to pay for his guesswork.

What about the mechanical side of things? Fuel side of things? Etc...

How long was he on it?
