Hi!

I had a timing belt failure a few months back on my 944 85b. Valves are exchanged and everything is assembled.

When i crank the car i get spark and fuel pressure but the injectors won't open. I got "tach-bounce" and i have also checked the reference and speed sensor and they both show roughly 1000 ohm.

I also got 12v at the injector harness, this should exclude that the wires are harmed?

As far as i understand the injectors are controlled on the same signal from the DME that gives the car spark/fuel pressure?

I have not checked with a noid light if there is any signal.

I have also tried to manually open the injectors with a battery with no success either. What voltage should be sufficient for them to open?

Any ideas are much appreciated!
