[Trev_m]

Here we go bought this car as a non runner 2002 172 changed ecu uch and key so that rules out ecu flywheel sensor & connector changed checked for broken wires from ecu to flywheel sensor & coil pack also tried different coil pack. removed an old cobra alarm to rule that out, It is priming the fuel pump immob light on dash fine just can't get a spark also swapped a few releys around the only one I hav'nt changed is the yellow one in engine bay.
I'm not good with wiring diagrams any help welcome.

Hmm, sounds like earth to fuel pump but its priming so can't be that?

You need to get it plugged in to check you're getting an RPM readout, which will rule out any TDC issue and to check coilpack pulses. Other than that, you'll be guessing!

As mini valver said, replace TDC. Renault revised the item a few years back so you'll need to chop into the loom.

Already change the tdc sensor an plug.

You need to get it plugged in and check you're getting Ran RPM signal from it though and to check you are getting a coilpack signal.
