Re: 90 Lumina 3.1 - Cutting off while driving or accelerating
Can you test the entire circuit at the ecm harness?
If there is 3 injectors on each bank, and each injector is post to be 12 ohms, then i should be seing about 36k to 40k ohms for the entire bank correct? I dont want to have to crack open this intake if i dont have to... Blah.
- Remove injector plug from ecm
- Identify injector bank 1 and 2 wiring
- Connect the positive lead of meter to the fuse for injector bank 1
- Connect negative lead to the bank 1 signal wire at ecm plug and test resistance (12 ohms x 3 resistors = 36 ohms + wiring resistance)
- Same procedure for Bank 2
I would assume with a +/-1% tolerance and with the wiring also causing resistance that i would be shooting for a 40 ohm resistance at the ecm connector. Anything Drasticaly higher or lower would mean pulling the upper intake. If they are in spec, then replace the ecm.
My theory work?
