1991 Chevy Lumina will not start unless I ground the red wire on the #6 injector
What is your question?
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.
What makes this problem better or worse?
Same hot or cold

RepairPal Certified shops can diagnose and repair your 1991 Chevrolet Lumina. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
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!
Would have gotten to you sooner but I had trouble changing my password. Thank you for the answer. I’ll find out tomorrow if that’s it.
Hope you find it. You’re welcome.
