  Many thanks to all who wrote concerning the trouble I'm having with my
injector troubleshooting.  Before I got into anymore "trouble"  I checked
all the grounds, as many connections as I could find, swapped out the two
relays in the engine compartment, and swapped another ECU just for giggles
(no change).  Then I got down to business.  My apologies to all as I failed
to mention in my first outburst, errrr, post, that I was unable to check
any voltages while cranking or in the first few seconds of fuel pump
activation as I had no helper to crank the key for me.  I had some help
today and found the injectors were getting voltage but it's incredibly low.
It peaks at 4 volts and within two revolutions, it holds at 2-3 volts max.
I have NO idea what could cause that or what to check next.  I checked the
relays and they are getting proper power where they should and have ground
where they should.  As I mentioned earlier, I swapped and swapped back on
the ECU with no change.  I have TWO batteries in parallel on the business
side of the house so no issues there with that voltage (roughly 1800+
cranking amps so it's got rotation).

  Otherwise, she's dead in the water.  Weird, really weird.  I've "jiggled"
all the wires I could find while cranking it over, swapped out all I could
with known good parts.  I MUST be missing something.  One thing is,
it shouldn't be a short or broken wire as it's getting a steady (albeit,
low) voltage.  All you EE types notice that I said, "shouldn't" NOT "can't"
:)

  I wanted to get this out earlier but had to run to work and just got off
at 1230 a.m. EST.

  Anyone?

Thanks,

TJ
