Your injectors are firing? How do you know? They are ground controlled,should have 12 volts to them,with key on.Whats your fuel pressure?Needs 12#s of fuel pressure.Can you hear your fuel pump run(for 2 seconds) when the key is in run?

i know its gettin fire because i checked the wires on the injectors with the key on. fuel has been a concern, but i know its getting fuel and i can hear the fuel pump run. does it have to have 12#s of pressure just the work the injectors? or could it be a peice of trash in the TBI? anyhow, i am getting a kit for it and cleaning the TBI.

With the key on you WILL have 12v, When cranking,there will be a toggling ground at injector,every time injector gets a ground,it fires.Check your fuel pressure,my experience is the injectors dont go bad very often.Fuel pumps are real weak,I replace 2 a week at my shop.PLEASE,check the fuel press.first.Will it start on carb cleaner?
