Re: 95 S10 4.3 No injector pulse Help Please !!!
Do you have 12 volts to positive injector side?
Confirm good fuel pressure.
Check for good hot blue spark to all plugs.
Check for injector pulse with a injector pulse noid light.
The PCM uses groun to neg side to pulse injector?
Is pcm pulsing ground?
