That damn tpi!!!

Have a question--My injectors aren't firing so I bought a test light for them--not getting any spark from cranking--also not getting any power to ecm(also no check engine light)--so I run a hot lead to ecm--still doesn't start--run a hot lead to injectors in ecm(forgot pin #'s)so now it's hot--tried cranking w/test light-still nothing--now what?? I'm gonna wind up parting this car out!! Any ideas??
Also one of the hot wires touched the ecm and sparked--think this fried the ecm??
C'mon guys I have faith in you!!

I don't have a pressure gauge, but the fuel pump is hot wired directly to the ignition.
It's definitely getting fuel pressure and spark. Just found that the ecm isn't getting any power to it--shows hot on the fuse panel(ecm fuse is hot)Also the inj. aren't getting any juice either--not pulsing on.
Have any ideas?
Thanks for any and all help!!

There may be another another 20 ampere ECM / fuel pump fuse in line near the battery.

you might want to check out the VATS system, I had the same problem when I swapped engines, I was getting, fuel and spark, only difference was mine would crank, start, run for 1 second, and shut down. Only reason it did that was I bypassed some part of the system with the new computer. But I would check that out, you might find your problem
