The ECU is not involved in switching the 12 to the ignition coil or the
Hall sensor. Check to see if 12 volts is getting to the coil could be a
bad ignition switch or connection on the fuse box. The plug connections
will heat up and fail. Note that there is no fuse protection for the
ignition coil, ecu, or fuel pump. The 12 goes from the ignition switch,
into the fuse box and comes back out in another connector and then goes
to the coil. Find the wires that go in and out following the Bentley
schematic and then jump the two together. If you unplug the connectors
from the fuse box, you will probably see the burn marks.

Subject: No spark, no hall juice, tech help request.

hey,

I have been helping a friend in the cold rain and snow here in VT with
his
van. He has no spark from coil. so we checked the hall sender (replaced
recently, by one of the POs). Anyway I proceeded to check for the
required minimum
10volt signal from the ecu at the hall efect sender wires and I had
nothing, now
the bentley says "replace ECU" in this instance. NO problem, Done< I
have
three good ones. NOPE this aint workin dude. SO Me thinks that we need
to replace
the wiring harness or chase the wires till we find the short or broken
wire.

ANy input? previous experience not neccessary.

Thanks
