1991 Chevy Lumina will not start unless I ground the red wire on the #6 injector

Has good spark, plenty of fuel, fuel pump is working. When it does start after grounding the injector it runs like a top. I ground #6 because it is accessable.

Injector driver ground is located in front of intake manifold - under p/s pump ‘area’ .. It’s likely corroded .. Same ground for all injectors - when you jumper ground to # 6 - it restores that circuit.

That might not be the problem but it sure sounds good!

(I’ve had that problem on a few of em)

Good luck!
