What is litre size of engine? Can you check for applicable trouble codes? If no spark at the plugs, check for voltage on pink wire at ignition module, should go hot when you turn on the key. That is fuse protected. Black wire is ground, check that also. If your sure the crank sensor--connector--wiring are all good. Then, if voltage and ground are good at ignition module, I suspect the ignition module. I can't be positive without some testing.

Without an rpm signal, the computer won't ground the injectors. If that is what your asking?

Just to add, The fuel pump relay supplies voltage to injectors as well as fuel pump. Best to check voltage with engine cranking. I believe gray wire is voltage to injector. I'll have to double check the color.
