was working fine left for 2 weeks then would not start ,theres no spark or fuel changed fuel pump,still would not start theres a light that flashes on dash,was told could be nats ,changed ecu and key reader and still wont start,tryed ecu and key reader in mates car and starts his car,
nats just cuts the injector signals on the pre-coilpack models, and they usually fire up for a few seconds if you drop some fuel down the t/b.
have you ripped out any wiring ?
