having trouble with my fiat punto 2001 .. wont start , no spark to injectors , have changed both coil packs, new ecu, new crank shaft sensor still wont start .. if anyone can help with this problem or has heard about others being like this could you let me know please or is there anythink else i need to change ? car has only done 28k .

Does the code light go out? And where did you buy the replacement ECU from

Who ever did the work in that order?

If no fuel past injector and no spark it has to be the TDC sensor. It could be the ECU, but I've head of no cases of an ECU fault creating that issue.

thanks for the suggestions will try them out

please could you tell me the location of the tdc sensor ? crank shaft sensor has been changed

TDC sensor is crank sensor. Did they connect it?
