I have a 1988 GMC S-15, there is power to 1 wire of the one relay and 2 wires of the second relay on the truck. But there is hardly any power to the fuel pump and constant power at the injectors, all 4 wires. Yet the noid doesn't light up and if you ground the left side with the noid attached it does.The truck won't start, the fuel pump don't come on and if direct conected it does work. ANY CLUES?????? I am lost, and as I am a woman I like to ask for directions......... Thanks y'll, Tonya

I forgot to say the TBI is the Model 220. The two on the driver side of the engine fuel pump relay, a little black square numbered 7103 and another one numbered 8370, I think, they have clips attached to them containing 3 to 4 wires each. But they are about 1 to 1 1/2 inches in size and attached to a metal clip on the drivers sidewall in the engine.

This info doesn't mean a thing to me.

What are you trying to fix?
