Message Just got my Ecu back from ash, retuned for DW 550 injectors and had it all wired up. Plugged in.
Now,...car sounds like a Subaru.
No fuel smell except from the exhaust,so no leaking.
Cylinders 1 & 2 have fuel but no spark. Unplugging the coils changes nothing on those 2 cylinders. All runs the same.
Plugs soaked with fuel.
Swapped with 2 know working coils,...same.
Swapped plugs with 2 diff cylinders,..same.
Checked wiring of injectors and it is correct and does tick and sound great.

Could the Ecu or prom chip be the cause. Everything else is working except on those 2 cylinders. Car runs but shakes and of course sounds rough.
No codes either.

Ideas?
