injector problems
 

Hey guys my 86.5 supra non turbo has a bad no#4 injector it does not fire i have checked the contacts and they are good it will run good somtimes but not at others

try joining the white/blue stripe wires together... get a piece of wire and tap to #1 injector & #4 both wires on those injectors should be white w/ blue stripe

let us know if it starts working :)
