Re: 94 Excel Suddenly died
I believe the connector is in the bottom of the fuse box. There will be
several pins there, but I believe there's something like 10 to 14 spaces
for pins total.
If you go to www.hmaservice.com and go through the fuel section of the
shop manual, it'll show you how to do this.
I'd be very surprised if you can get anything out of the digital meter.
The codes are displayed as two digits with the long sweeps indicating the
tens digit and the short sweeps indicating the units digit.

Re: 94 Excel Suddenly died
I went to www.hmaservice.com and went throught the fuel section. It was
very helpful. I was able to locate the connector in the fuse box. It
showed me which pins to use. I bought an analog voltage meter. I
couldn't get any results out of the meter. I had the ignition on, my
ground was solid - I checked this by touching the positive lead from
the multimeter to one of the fuses where I got a reading. I charged up
the batter so it had a full charge - what is going on? The manual said
that if the ECM was shot - You would get a constant reading with the
meter. I really need some help! Thanks in advance.

Re: 94 Excel Suddenly died
Last night I actually read about the check engine light and how it
should come on if there is a problem. It doesn't come on at all when I
turn the key. I did check to ensure the ECM was grounded. I wasn't sure
how to do this so I simply ensured that the bolt used to fasten the ECM
to the vehicle was snug. It had two black wires under it so I figured
it was some sort of ground. How do I check for Power and ground to the
ECM?

Re: 94 Excel Suddenly died
On the www.hmaservice.com site, there's a tab labeled "ETM." This tab
leads to the schematics. You'll be interested in the MFI schematic.
Simply check for power in all the wires that should have power (using a
test light or your voltmeter). Simply unplug the ECM and check the wires
in the harness. If all the wires that should have power do have power,
then check your ground. Choose one of the powered wires and then touch
the ground wires and make sure you get the typical 12V.
At this point, I suspect you may have a blown fuse or a bad MFI relay.
You might wish to check all the fuses inside and out first.

Re: 94 Excel Suddenly died
I was able to locate the MFI - I ran out of time last night or should I
say the Mosquitos got the better of me. I will be checking the MFI
tonight. Last night I was pretty frustrated I was almost giving up
hope. But I think that you may be onto something with a bad MFI relay.
I did check all the fuses inside the car as well as a couple of fuses
located close to the Windshield washer resevoir. The seemed to check
out just fine. Is there any other locations I should be checking out? I
have printed off pages and pages from the hmaservice website. One
question - to check connectivity for the ECM ground, can I tapp into a
fuse with power and touch the ground wire to the ECM grounds on the
wire harness?
