I've got an em4-6f system and have been trying to trouble shoot the car and I'm stuck. The car won't start. I checked all fuses with a ohm meter, the coils are firing (all 3 coils), and there is 12V present at the injector plugs. The injectors don't fire when cranking tho. I tried a noid light to verify this and I was correct. If I test fire them with a jumper wire they click and work. I assume this can't be a hall sensor problem as I'm getting coil fire. What should I check next? I unplugged all the injector harness wires and checked for any sort of corrosion and found none. I don't know if this is worth mentioning or not, but I washed the car about an hour earlier (but not the engine bay). I stopped for lunch, started the car right up, drove out of the parking lot and then it died right as I pulled out on to the street. Let me know what I need to look for, I'm running out of ideas.

james!!! hey!! its andrew! the manifold is great btw...

anyways, have you checked all the grounds? isnt that the first thing you always are supposed to check for with the car?

I had run new ground and power wires, checked everything I could think of. I ended up calling Barry at SDS up once the canadian holiday was over and we talked for awhile. We finally narrowed it down to a faulty map sensor telling the car it was at full vaccum...therefore it wasn't getting any fuel. It ended up being a pinched wire that had eventually grounded itself out after rubbing for quite some time.
