928 will not start
 

I have 928 from 1984 and it has been not drive 5 years, starter works normaly, i think I hear that fuel pump works, but he didn't spark not from both ignition coil. I check computer at mechanic and he say that everything is ok. I chek the vire on halo donor and on that vire there are some electric but not the right electric. I try to reinstall commutator and there nothing happend. does enybody help me to start engine.

You need to check for spark, fuel and compression. Many times the ignition resistors on the inner fender well go out or break down over the years. I would:

Run compression check
Remove fuel injectors and have them checked
Replace plugs
Check fuel pump (jumper relay and flow out)
Check for spark
Check all sensors

Do you have the service manuals?

Sitting 5 years I suspect.

Gas is bad, drain the tank and flush, replace the fuel filter when done.

Connectors have corroded, clean all the ground points, check all the fuses, pull and reseat all the relays.

Where are you located? Maybe someone local can help you.

I try everything that you say and get nothing, is there on engine something that may cause the eror.

Yes, several things can cause that, other than what you have tried.

Where are you located? What else can you tell us about the car?
