Hey guys,
I am back after 2 or 3 posts and no answers. Fuel filter and fuel relay replaced. Slow or fast car stumbles and only restarts after repeated gas pedal apps.
Battery good, grounds good. Pumps run on fuel relay jumper but car still stalls.
How about that check valve at pump outlet? Would L or R turns close same?
Somebody suggested partial alarm system failure i.e mercury switch. Any such in factory system for an 86?
Car runs great..in straight line!
Going nuts!
