91 trooper injector problem
 
Have power on both sides of my fuel injectors but can't get them to fire......and they are new injectors

yah I am not sure about that, i would try both; cant hurt. also i would try holding the gas down once you jump them, cause that should throw code 51(i think) for sure. i would also pull your efi fuse for a min to try and reset that damn CEL, i know when you disconect the bat it resets it too but...

did you disconect your bat first thing when you started pullling your head, dont think i've heard of the cel staying on solid when checking codes.
thats the schematic i was reading, remember you cant have voltage drops if current isn't flowing, thats why you see 12volts in, 12volts out, ONLY if it was plugged into the injector.

never used nor learned about those 'noid' lights.
