The fuel injector will not open. put on new computer. Injector still will not open. There are two wire to the injector. The red wire has constant voltage with the switch on. I installed a jumper wire to replace the blue wire from the injector to the computer wiring harness. No help. Don't know what else to check.

did you remove the filter cover and see if the injectors were firing when you were trying to start it?
