New owner; whoever owned the truck before the previous owner somehow wired from the fuel pump to a kill switch and around the inertia switch, which isn't currently in the truck but if you flip the switch it'll run and drive. Problem is it wants to stall if you're not constantly giving it gas. I don't know much about electrical but when my friend got the truck originally he noticed the other individual had ran about 4 different grounds to one body ground, on the front by the radiator. Is there any specifics to the wiring of a normal vehicle with the inertia switch in place, this vehicle's being out and wired around, and why the vehicle wants to stall regardless of being wired around the switch.

I'm sure someone has wired around one before so all advice welcome.

It does idle longer now that I've rewired it. Would die almost instant, sometimes even when just braking from 30. Once warmed up you had about 45 seconds to a minute before it stalled. Since the rewire it only stalled after revving it trying to check the idle but it had idled about 2 minutes (no clutch in neutral stalled it. With clutch in got the two minutes out of it.

Thanks for listening,
