A few months ago my 1993 Ford Taurus stalled while sitting at a stop
light. It started right up in about 2 minutes. No more problems for
two weeks. Driving in town car just stalled. No warning. Started
back up in about 2 minutes. A week later same thing. Always starts
back up with in 2 minutes and runs fine. Never a warning. Check
engine light never comes on. All electrical parts keep
working(radio, lights, horn, electric window). Wehre should I start
It wouldn't hurt to put in a new fuel filter before you start anything else as
a dirty or plugged filter will cause that also...and that's something "cheap"
and easy to do.
When was your air filter changed lately?
If it can't breathe well it will stall too....
Another possibility is early stage failure of the ignition module. Common
problem on Fords of this vintage. Heat from the engine causes failure which
will often disappear after cooling off for a few minutes.
was the ignition, but it turned out to be the CCRelay module, the one on
top of the radiator...the relay in the box for the fuel pump would
sometimes work and sometimes not... cost me about $50 at napa for the
part... for wanted $150 for the same part... the way i found what it was
is i put a gas guage on the engine and found that in most cases the fuel
would pump up to 40-45 PSI, but sometimes it would not pump up at all...
took about 20 or so attempts for find this out... then i went to the
power wire from the PCM(power control module) and found it had power to
the CCrelay module, but that it did not energize the wire that came out
of the CCRrealy modue leading to the fuel pump for sometimes... i guess
the relay inside was sticking or somthing.... i was gonna take it apart,
but gave up and just got a new module.....later took the module apart
and found it was too involved, alot of resistors, capacitors, and
relays... and other parts that i am not familar with.... if you can take
off the plastic lid on top of the radiator and look down at the wires
going on the plug from the side of the relay(the black metal box thats
attached to the top of the radiator(about 3 in. by 4 in. about 2 in.
thick, has a wiring plug on the side of it with about 60 pins on the
plug.. coming off of pin No. 8 is a wire (color is pink with a black
strip on it.).. this wires goes straight to the fuel pump and shuld be
getting power when the key is in the run or start position... to test it
i took a long straight pin and put it into the wire(make sure it goes
into the center of the wire and hits the copper or it will not work)...
i then took an multi meter and checked voltage at this location and then
the other lead to the ground terminal of the battery.... if the relay
sometimes workd and other times does not work it will take time to find
the problem.. i think i did this about 20 times before it showed up..
with a person in the car i looked at the meter and could see 12 volts
beiong measured with the key ON...in the run position... then told them
to turn the key OFF. there is no voltage with the key off.... i then
yelled ON and they put it in run and there is voltage.. then Off, no
voltage... did this about 20 times and the problem showed up..the key
was in the run position and there was no voltage to the fuel pump.....
Problem solved...... got the new CCRelay module and problem fixed.....
hope this helps.
