The Digifant 84 tintop with ABA hybrid gas motor, stuck in there using the
Vw diesel mounts and 5 sp trans. Digifant, can be considered a stock van
for this purpose.
I had an "engine sputters and dies, starts, but won't keep running"
event s week or two past, so I removed the pre-filter and shot some (15psi)
air back into the gas tank to perhaps clear the fuel screen... That worked,
but yesterday, in a blizzard in Tonapah, NV. It did the same...started,
but in a few seconds, sputters out again....ok, fuel pump sounded normal.
Flexed and squeezed the hose from the tank to the pump, thinking "ice in
the fuel line?"...Key off, start....run right for a few seconds, then
die. Key off, then start, it repeats...So I swapped in another used but
good temp II sensor...and that "fixed it"....I thought. (this pit-stop to
change the temp II took about 1/2 hr, the time sitting may be what
"fixed"it)... I did NOT want to lie in the snow and swap fuel pumps... But
100 mi. down the Hwy, leaving Beatty, NV to cut across death valley, after
topping up with gas, it sputtered....for maybe 15 seconds, then cleared up
and ran right again....So that was 3 times screwing up...and not very
comfortable-making, heading out across Death Valley with the So Cal freeway
system ahead, on Sunday of Thanksgiving weekend.
A few more symptoms this glitch happens, I think, when it's really
wet, but that could be wrong...My fuel consumption stayed pretty
normal...26 mpg with the wind. All the other instruments stayed normal.
I'm figuring, and here's where some helpful opinions are solicited, that
in no discernible order of probability, my problems must be one of these
things:... A partially plugged fuel pickup in the tank... The Temp II
sensor is intermittent.... The fuel pump is faulty, sometimes..the pump
wiring gets wet...
I am not in a great situation to throw parts at it right now(in the
desert for my Mexico dentist appointment)..so wadda ya think I should begin
with, besides checking wires and connections? thanksHave something to add on this topic today? Revive this thread in the forum »
