First of all thanks for all the help you guys give it is greatly appreciated .
I'll start with what the truck is and how it runs , It's an 1987 with 2.9 automatic with a/c. i purchased it with 56,000 miles and a stalling problem which i was led to believe just started, my bad.
It will start and go to high idol and run for a short time in park then die like it runs out of fuel(both fuel pumps and filter have been replaced) checked fuel regulator no gas in vacuum line.Fuel pressure is 30-40 and dosen't seem to bleed off.
Parts replaced.
TPS,Air Charge Sensor, Water Temp Sensor (twoWire) ,Distributor with Cap and rotor,PlugsAnd Plug Wires,Ignition Module .
I have verified 12v at fuel pump relay and eco relay on key on and when running and while it dies.
Spark has been verified to be present with no change wile running o r when it dies.
Black smoke is coming from tailpipe but it acts like it is starving for fuel as sometimes i can spray carb cleaner in the throttle body and it will keep it running.


I can drive it down the road and it runs ok but as soon as you press the accelerator it acts like you cut the switch off then it spring to life and takes off.
it dies much quicker in park than in drive , in drive it will sometimes run for 10 min parking break on and wheels scotched. before stalling . then when i try to start it will turn over several times before trying to run again.

I unplugged the vacuum line from the MAP sensor but left the elec conn hooked up and it tries to run in park for a little longer but still stalls.
I have been read lots of post but none like mine any help will be thankfully accepted.
Link to video ff to .22 for stall.
