PLEASE HELP!!90 geo tracker no start, no injector pulse
I have a 1990 geo tracker with the 1.6 5spd 4wd. It turns over fine, has good compression, it is firing the spark plugs, the engine will run as you spray fuel in throttle body. Have checked fuel pressure ant it is with in specs. Tachometer will move up to about 300 rpm when turning engine over with starter, seems like the computer is not sending signal to injector, vehicle was running when it was parked just will not start now cranks over fine.. Have ohmed wires from pcm to injector and both are good. Have checked all fuses under hood and dash and see no problems. I am sure there is something that is causing ecm to shut injector down maybe throttle position sensor or somthing, looking for some advice from someone that has been down this road.
