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?

 

You want to do this ground testing with the ECM *unplugged* and you want to
do it from the ECM connectors. You can use a voltmeter or test light with
one end on a wire with power (or a powered fuse like you mentioned) and
the other end on the terminal in the connector. Just touch the terminals,
don't stick your probes into them-- this can damage the terminals.

It's been a while since I've worked on one of these. I don't recall
whether there is a sizeable underhood fuse block or not. If so, it should
be a black box of reasonable size and pretty much readily identifiable.
