Today has been a **** day.
This automotive problem has been ongoing, so I am going to use it to distract from my other issues of the day.
The vehicle: 1994 ram 3.9 v6, 5 speed. A billion miles. Bone stock except for a gutted cat.
This truck runs GREAT until it gets thoroughly warm. Then when you shut it off and go to restart, it's flooded. When driving it doesn't really act up that I've noticed, but park it and let it heat soak, and it's flooded. You have to hold the throttle WOT, and then it'll clear out but if you don't get moving...... glug glug
All 6 plugs come out BLACK and it'll stink my whole yard with fuel vapor. Doesn't smoke until it floods, and then it smoked black. Idle is great until it's Noah Time.
New plugs didn't fix it, cap and rotor are new, tried another coil, the previous owner replaced all manner of sensor with factory ones. He even replaced fuel pump (I got 40 psi when it's flooded, didn't try when it would run).
I can't even figure out any codes. No CEL.
The clean idle and lack of smoke tell me that the plenum gasket is probably ok. There's no downstream o2, since it's obd1.
Any advice on a magnum efi that floods when hot?
