while driving,car died suddenly,no power going to coil.Had coil and
ign.control module checked at parts store,both tested good.computer had
code:211(pip) and code 212 short to ground in spout circuit. Went ahead
and replaced distributor,pickup coil,ign.module and installed new
computer.Ran good for about two blocks and died,back to same problem.
See that big connector you plugged into the nice new ignition module on the
side of the nice new distributor?
See the smaller connector hanging off the original wire bundle, a few inches
back, small and square, about the size of your fingertip, with a square
"jumper" plug that you can pull out? That's the spout (SPark OUT) jumper.
When inserted, it lets the nice new computer control the ignition timing.
When removed, the computer locks the timing at a preset value.
When grounded, usually by the wire bundle being cut or rubbed through
(somewhere between the distributor and computer) allowing the bare wires
to touch body metal, the computer and ignition module screw up, the
engine shuts down, and you get to walk home.
I would get in there with a good light, and trace that bundle as far as you
can back towards the glovebox where the computer lives, carefully checking
for any fraying or chafing of the outer insulation, particularly where the bundle
goes through clamps, or makes sharp turns.
See the ugly grey sensor mounted near the egr?
thats the egr pressure sensor!It's electric! That explains why it shorted
out causing the computer to shutdown after a few minutes of
operation.Unplugging that bad ugly grey sensor made the bad problem go
