I ha tried a noid lite hats how i know its not getting power. and I'm pretty sure there isn't a relay for the injector, if there is i have no idea where it would be, this car is almost too old too have injectors makes it really frustrating not knowing what is going on I have tried the internal diagnostics many times with no problem codes found. these earlier versions of pcm's were a real piece if you know what i mean. thank you though!!!!!!
