Trying to get this new motor fired up but inejctors arent firing. Ive checked all grounds they are fine,fuel pump is fine,fuel is returning to the tank so no clogs,battery is fine,there is spark. Even swapped in some car injectors just to see if maybe my injectors were bad and they didnt fire either any ideas im getting tired of messing with this thing and jsut want to ride wish there was a shop or someone close by i coudl drop it off at and pick it up done

Make sure you dont have your crank senser and you water temp sencer backwards.

I just had one of them not firing. I dropped it off at BW. Cord said one of the connectors was bad.. He swaped injectors and the right side which wasn't firing still wasn't so it was kind of a no brainer electrical issue for him..

I'm not sure if this is recommended by some of the technical guys or not, I had some that were "stuck", and blew them with compressed air. I've done it to 2 different "stuck" injectors so far and it seems to work. I think they just seem to plug up or sieze up if not used in long while...
