Question type: Maintenance & Repair
I stuck the battery in backwards like a moron
and now the injectors won’t spray I put a new
computer in it and a relay and a pump and a
filter and there is fuel pressure up to the
throttle body but it but still won’t spray It has
power to the plugs and it runs when you poor
fuel in but I just can’t figure it out
