You might want to get a diagnostic tester.
There are cheap ones at WalMart that come with a very
good book to tell you all the codes. (beep sequences).
Just make sure you read the instruction through all the way
before using one of these diagnostic testers.
I have a 95 Probe with a 4 cylinder engine. I've got plenty of spark,
the fuel pump is working, and yet the injectors don't seem to be
firing. Can anybody help me with this mystery. I know very little
about these cars. The fuel pump does prime up before actually turning
the engine to start it. I just can't figure out why it won't run.
Thanks! Any help appreciated.

I'm but the donator of the Probe to a family member. It was
originally my son's car and it up and quit running.. even despite
that, and the fact that the body is mint, I took over the car and
donated it to my older brother for fixup for his daughter's first
I was down working on it last weekend with my brother, and did plug
in a scan tool and pulled several codes. everything that's needed to
make the car run is there. We turned the engine over while listening
for the intjectors to fire, and there didn't appear to be any sound
coming from any of them.. My brother's first instinct was that the ecm
was dead, and or at least the cirucuit that fires the injectors is
dead. My feeling was that the ecm is good, but there's some other
underlying problem causing it to not run. The engine won't even
sputter. We don't know enough about the controls in this car,so we're
simply taking pop shops in hopes of finding the problem.
HAve you checked timing?!!!!
You're asking for help but you arent sharing your info.
The ECM isnt DEAD, may be crippled.
Wanna throw money at it? Find a yard that likes probes.. they'll have plenty
of ECM's on the shelf
I'm starting to get the idea that you would like one of us to go into the
EVTM and post the troubleshooting tree, Well maybe someone will but I aint
gonna do it.
The REASON for these boards is to share what we know, exercise our minds
analysing problems, and learn something in the process.
You are posing a puzzle without setting out the assumptions OR answering the
clue questions.. which leaves us with nothing to proffer but wild ass
So either play fair or get the fuck out.

I figured if the ecm is storing codes, and they can be read, then
there's a good chance that the ecm is still good. My brother though
perhaps the cirtuit that controls the injectors might be dead. I'll be
heading down there this weekend and I'll bring the codes back and post
Alll of your help is greatly appreciated.
Ken, post the eec codes from your scanner, and what your book says they are.
Also, what is your fuel pressure on the rail while cranking? Sometimes the
pump will run but will not pump, and/or your regulator could be stuck too.
Have you tried some ether to confirm that the mechanicals are capable?
How did you confirm that you have spark?
From the sound of everyone, it seems that unless you do the job yourself, the
service station mechanics can't fix the problem.
I don't have a home or a garage, but do you think it's worth it to buy the
Chilton or Haynes manual to try to troubleshoot the problems myself? I'm
pretty handy with electronics, but have only recently gotten into car repair,
and I'm very much a beginner.
My brother and I are capable mechanics, and it's what I do for a
living, although my expertize is on large trucks, cat engines, and the
like. I don't own Ford products, and have a very limited experience
with them. We've got Haynes manuals, and as per usual the information
in the off the shelf manuals is sketchy at best.
I'm guessing from another post that there may be a timing problem,
and the problem isn't limited to the injectors. The car was brought to
the local Ford dealer where my son is a dealer, and they wanted to put
a new engine in the car. We're are simply trying to get the engine
running to see if it infact does need an engine, or just some other
work. The engine just up and died on my son and it ran fairly well up
till that point. I'm not looking for the answers, just an idea where
to look since everything else we've checked (ie ignition, fuel
delivery, relays, fuses, etc) had turned up nothing at all.
The car also came with a factory alarm system, and because the key
was needed every time to get in and out of it to avoid setting off the
motion alarm, it was disabled.
You indicated you have checked the basics. You have fuel pressure (hear the
pump running?). You have seen the spark? Usually a mechanical problem does
not show itself by the car simply dying without a lot of fanfare (like a big
Just had this exact problem with my son 87 Taurus. Driving to the school
(1st day) the car just died. Had it towed home. Discovered right away the
fuel pump was not running (and was recently replaced). Armed with my
voltmeter and the electrical diagrams for the car I went backwards through
the fuel system to discover there was no power to the ECU. Turned out to be
a corroded connection (crimped connected inside a rubber sleeve) at a
fusible link that powers the ECU. Without the electrical diagrams not only
would I have never figured it out, I would have never found the link which
was located at a harness near the bottom of the radiator!
Last 3 failures for this car have been electrical. good luck!
