I have a 1990 chevy c1500 2wheel drive. I bought it not running. I have found the problem and it the tbi injectors are not hooked up. The 4 wires on the 2 injectors are red and the 4 wires going to the tbi are red,blue,green,white. what wires go were? Thanx for all your help.
The red and white wires are the power to each injector and are actually hooked to each other in the harness. These 2 wires should be hot when you turn the key on. The green and blue wires are the grounds that lead back to the ecm. The red and blue wires go to the passenger side injector (red is far left as you face the vehicle). The white and green go to drivers side (white on left as you face it)
