My wife has an old Mondeo. It's one of the first Mk2's, built in
belgium in nov 1996 and registered in feb'97. It's a 2.0 litre Ghia
hatchback, manual box.
The problem is that it will start OK from cold but won't restart once
the ignition circuit has been active for about fifteen minutes. A
better explanation is needed.
Start from cold, runs fine. Drive around normally.
If we leave the ignition on for some reason (such as driving the car!
But I've tested it by turning the ignition on from cold and leaving
it, engine not running, and it still happens.). Stop for a level
crossing / stall it /
nip into a shop or something THEN try to restart
the car. All we get is the engine turning over without any attempt to
fire for about five seconds. Then the starter motor stops, the wipers
flick across a couple of times and thats it. This is the wierdest
part of the problem. At first I thought I was knocking the wiper
switch but no, it's the car wiring at fault. We have to leave it for
three to four minutes for... something to cool down?... then it will
The battery is a new (now 8 months old) heavy duty one. It is always
fully charged, it always starts well from cold on even the most frosty
of mornings. (We've had this fault for over a year now.)
My (non) diagnosis:
The starter turns at full speed, not slowing down, not chattering.
Therefore the motor itself seems OK.
The motor turns, so the the wiring to the solenoid must be in place.
The engine makes *no*
attempt to fire, therefore the ignition circuit
must be compromised somehow. Or is it the ECU?
The flicking wipers make me think that a current is finding the
shortest route back to earth. Which means maybe an important earth for
the starting / ecu system is broke?
Can anyone point me to a possible cause? Are there any common faults
that could manifest themselves like this?
Thanks for any help.
