hi im pulling my hair out tying to get my yota goen. i put a noid light on the wires for the injectors and nothing but if i use a test light i get power at both wires when the key is on and im cranking it. i can put gas down throttle body and it runs the gas out.also if i put noid light on cold start injector it lights up so that works. PLEASE HELP!

 

similar problem with mine, the injecors werent getting a signal. i replaced my computor and that fixed it

 

do you have the air intake and the afm connected

 

yes the maf is hooked up and checked everything. think its the computer?? i dont get a check engine light at all except when i put a test light on the check engine wire coming from computer.?? what does that mean? i have a 1985 and i was told that 85 stands alone, soo i have to have a 85 computer if ne can help that would b GREAT! And if i cant find a computer i think im just gana pull it out and put the 4.3 vortec in!! Thanks (its driving me 2)

 

check the wiring harness for two ground wires that goes to one ring, it should connect to the intake that is the ground for the ECU to ground the injectors for pulsating. At least that is what was wrong with mine when I had the exact same problem.
