Injector not firing

[Yamahaulin]

Ok just go new motor fired last night. I'm only running on the the two inner cylinders. The outer to fire the coil but it's not firing the injectors. I have power and ground injectors 1 and 4 but they are not pulsing. What do i need to check.

How about your ecu, and the wiring to the injectors.

Check the resistance in the injectors. Should be 2-3ohm's. If it doesn't check out then your injectors are bad.

Ok, so i've swapped injectors around and the two dead cylinders are following those injectors. I don't feel like that's the problem so i went and bought a noid light to see if it was pusling them. The light is soo weak it isn't funny, i hooked to my jeep and it has bright light. I'm thinking i have a power probem so i unhooked on plug and put the noid light in the ground side and added my own hot and the light got bright when it pulsed so i think that's my problem. So question is where is the power supplied from to the injector plugs so i can track down my problem as i don't want to rewire my own 12v hots to the injectors but will if that's what i have to do.

check the cam censer that was what was bad on mine and 1 and 4 where not firing also check the coil

off towers high side 11.3-15.3 kilo-ohms the red and blue on back .77-.95 kilo-ohms

Ok, found the problem. Found some bad connections and the replaced alternator and problem fixed. The noid light is dim likely because of the resistor packs.

What connections were they and did that solve the dimness or after the alternator and what was your issue with the alternator
