I have replaced everything fuel wise and
electrical except computer. Truck will start
and run fine as long as I continue spraying
fuel into throttle body. I have plenty of fuel
pressure I think injectors are not pulsing. I
tested them with a test light and nothing
please give me some advice on what to do
next it's the only vehicle we have and I live
in the country with my wife and daughter.
Have you checked the injector for power then for pulse while cranking? see pic.
According to this diagram tennisshoes shows, power is coming from the fuel pump relay, and yes you have to check the pulse (voltage or power) while cranking.
