Currently van engine will not turn off unless I block air intake.
History:
1) Van is L400, converted to WVO.
2) recently (Less than a week) van was not accelerating at start from a stop. Engine idling and starting without any issue, but when I step on the peddle, acceleration would be delayed and occur after 2-5 sec delay. Worsening over the week. The worst occured yesterday, when on a steep incline, van would not accelerate at all. Had to back up, put in Low and then get up accceleration above 2000 RPM, then normal operation.
3) Left van with girlfriend (not the problem!) and when i got back to her, van was running, but no key in ignition. Tried normal stuff to turn it off. No luck. No issues with engine temp, very smooth running. Took of battery Negative, which did nothing.
4) Engine ran best it has in a while during 200 km trip home, with no lag in acceleration. Tried turning it off a couple of times, but no sucess.
4)Got home, blocked off air intake and soffocated engine to stop it. Started up engine and it started normally and ran smoothly. Acceleration was normal. Engine did not shut off. Drove it around a bit and..
5) Instantly, had full guage shut down. No gearing (L,2,D,N,R,P), RPM, speed, fuel, temp, Tac, Info pod, instant door locks. Other elctronics normal, Signals, Headlights, clock, stereo, interior lights. Driving normally.
6) got the van back home, turned fully off (including engine). Turned it back on and everything was back to normal.
So, I do not believe in the paranormal, it's not a ghost in engine(girlfriend's idea)...But I am asking for any help in diagnosing problem.
May need schematic for fuel pump and wiring. Does anyone have that?
Thanks a ton for any suggestions,
