ive just finished putting my mates combi van together using an efi xr3i loom and using an ofab ecu,ive made the changes to the loom to run ofab management and i know it works as the loom came out of my own car which was running,ive got spark and the fuel pump primes ok and the fuel rail fills with petrol,the problem ive got is that the injectors arent firing so cant get the car started,the relays and fuses all seem fine and cant find any breaks in the wiring,anybody got any ideas atall please,the car is all ready to go but i just caant get it started,is there a possibilty that the ecu could be knackered or is it a different problem
