Was it that difficult to solve the firing order issue? I've been thinking about the EDIS system for a while but never had a chance to get in touch with. Which crank trigger are you using? Custom made or stock trail blazer one?
Not really once we knew the firing order for the donor engine. They are using an EDIS 36-1 trigger wheel from a ford escort and a custom adapter bracket and mount in conjuntion with the dry sump oil pump drive.
With the EDIS coil pack input connector on the right side of the coil pack the correct cyl. pairing is:
rear
1,6 connector
3,4
2,5
front
Once the initial timing check is done with a timing light and set for 10 deg BTDC - the rest of the timing adjustments are done in the tuning software. The car owner is new to EFI and after checking several advance points with the timing light against what the laptop was saying - he put the timing light away for good....
The one item that needs to be checked if you get no spark then try revresing the VR sensor wires - even if the wire colours are mis-matched. This bit us for a while.
