Battery has a full charge and connections all good? You jumped the fuel injector, voltage and ground? The voltage to fuel injector usually goes hot with key on and fuse protected. The computer pulses the fuel injector ground if the computer see an rpm signal. W/o rpm signal it won't ground fuel injector. If you have distributor, the rpm signal comes from pick-up in distributor through ignition module in distributor to pcm. Could be other issues? Any applicable trouble codes?
Yes battery fully charged it's a brand new battery. Connection are clean. Yes pos and neg. It clicks open. Will run when I hook injections up to battery to open then. Do you know what the volts are when the key is on? I'll check for any new codes
Did you check voltage at fuel injector fuse. Should be close to 12 volts. If no ground for fuel injector there will be voltage on both legs, positive and negative. That voltage you listed isn't correct. Sorry for the late reply.
I check it at the injectors. I will recheck at the fuse. Can I check by one prop on the injection one on neg?
you can use noid lite on injector plug, engine cranking, to see if lite will flash.
Just to add, it was the voltage wire to fuel injector that you checked for voltage, correct?
