Basically i have a s14a that wont start due to the injectors not pulsing to let fuel into the cylinders and i cant for the life of me figure out why and i need help desperately as japfest is fast approaching! (in depth detail to follow)
Almost 2 weeks ago now my car was getting fairly hot due to a hose going from the front mount intercooler piping to the IACV catching on the viscous fan and stopping it from spinning. So on my way to get a long hose so that i could re route it to prevent it catching i turned my engine off at some traffic lights to keep it cool and then when i started it again and went to drive off the engine bogged down and cut out so i started it again and then did the same but after a second time the car wouldn't start at all. (not sure if this is related to the issue and caused it or just a coincidence)
After getting home (got towed) i started doing tests on the car and found that i still have ignition from the plugs and also i still have fuel pressure into the rail as the fuel pump is still working but what i don't have is any fuel injection. There is a constant feed to the injectors as there should be but the earth isn't being switched on them when the engine is cranked over. I have checked that all the injectors open when i earth them direct to the engine or body of the car and i have also checked the continuity of the wiring from each injector down to the ECU wiring harness and it all checked out.
I was suspecting a faulty ECU due to either bad injector drivers or NATS but then after sending the ECU to H-dev to have the NATS removed it had already been removed so i presumed a faulty injector driver but then when testing my car on a friends working ECU i still have no injector pulse!! I then went on to thinking a faulty Cam Angle Sensor was the issue but then i tried a friends working one and also checked all the wiring from it back down to the ECU wiring harness and all the wiring was good.
I know this was long winded and do appreciate anyone that took time to read this but i really need help as i cant live without my car any longer and am open to suggestions of anything to try to help resolve this issue.
Thanks guys,
Brad.
