ok 20b experts i need help here PART 2
 
could hardly wait to try what I thought I had missed, so this morning I tried a couple things
that I thought would solve the problem.
first thing I did was found a ground near the computer that was supposed to be bolted to the body, which I had over looked when grounding the rest of the ground spots.
well that didn't help at all, then I remembered a shielded wire ground that had been cut, connected that to ground and when I did, a buzzing sound started coming from the transmission, before I pulled it back off, (for fear of burning something in the trani out) I tried to start it again,,, nothing:(
then I tried manually grounding the injector wires to hear if they would click,,, Nothing?????????
whats with that???? there is power to the injector, and it should open when grounded!
so I tried manually grounding the secondary injector (only for a sec, don't want to burn them out) and I heard a click!
Now I am wondering if the primary injectors are fried. they should click like the secondary ones.
well after I gave each secondary a click I tried to start it again and it started!!! wooohooo
I am getting some where now!
if anyone might have a idea what is be wrong with these injectors let me know.
more as I figure it out

Check resistance with a DMM - it should read about 10-12ohm for each fuel injectors.&nbsp If they don't check out, they are no good. :(

REDed> the resistance of all 6 injectors are the same.
Turns out that all 3 primary injectors are stuck
I have them off the motor now and hope i can get them working again, maybe a bit of light tapping might work them loose if not i guess they are off for cleaning:(
Who would have ever guessed that all 3 would have been stuck!

thanks
matt
