98 Contour, 2.5 Duratec, 50,000 mi. Just died on the road. Last week or so
the engine would cut out for a few seconds but, then, pick up again.
When it died, the Check Engine lite came on. Starter works, but no
Shop [not Ford dealership] says their analyzer is getting no response from
Does Ford have a history of ECU's going bad? Also, I've had a Superchip
installed since I first got the car. Any possibility that the Superchip had
an effect on the ECU?
Looks like you are going through what I am with my 94 Escort. Your problem
sounds like you may have an intermittent failure - I would start looking for
loose ground wires, or other connections first.
If it ends up being the ECM - I have been getting lots of quotes from
on-line parts recyclers in the 35-75 dollar range - not too outrageous.
Backyard Mechanic here on this list has told me that real ECU failures are
in fact very uncommon.
See if you are getting fuel to your fuel rail Schrader valve test
connection, to rule out a fuel pump problem, then check to see if you are
getting spark ignition. Check to see if your injectors are operating with a
test light. Is your timing belt intact? Has it jumped out of time?
Good luck - I'll let you know how I make out with mine.
THanks for adding that, Chris...
I should have mentioned the Grounds... that's the greatest real problem; I've
gotten used to looking for them through about 10 beater EFI cars.
First mode of failure is Grounds, second is EEC and fuel pump relays...
usually, in 80's, due to water incursion.
Otherwise, my statement is PURELY anecdotal... the guys here that do fleet
maintenance or real shop pro's would have more realistic input.
But I bet I'm right.... even "rebuilt" units are cheap... I'd bet they dont
"rebuild" at all... just test them.
Frank, have you tried removing the chip yet and seeing if it works then? If
it IS the PCM you can get a new "used" one really cheap from a junkyard, try
car-part.com. I know they had some around $20 for my '97 Taurus. I was
looking into a second one for some tinkering. Good luck,
Yes, I have taken the chip out, disconnected power [20 min] and reconnected.
On used engine computer, how do you identify which mods/versions of the
engine computer will work in my engine?
PS. Ford is telling me a new ECU is $1000 - does that sound right?
