Engine Performance problem
1987 Chevy Truck 6 cyl Four Wheel Drive Manual
I have a 1987 chevy truck throttle body injected 4x4 manual. The injectors are not firing.I have checked with a noid light, no pulse.I have replaced pickup coil in distributor, no pulse.I have replaced ecm, no pulse.I have replaced tps, no pulse.I have unplugged tps to see if in flood mode, no pulse.I have replaced map sensor, no pulse. Check oil -correct amount, pressure is 30psi on dash gauge. Fuel pump comes on and is getting fuel to injector just no pulse. The battery also has been replaced and has 12.22 vlts also on charge while cranking and trying to get truck running.I have also checked voltage at injectors which is 10volts on the power side. Please help what else do I need to do to get injectors to fire. Also truck will run when fuel is poored in throttle body.
have the same problem?
