2000 Dodge Intrepid Repair Question
I need some advice on a fuel injector problem
The injectors for this system does not fire at the same tieme as they are individually controlled. However you can still piggyback eventhough system is thus, it just allow the injector to fire earlier and and make the engine run smoother but the MIL is not going to go off.
The computer could be expensive but if it is a wiring fault, it should not be. Locating a break in wiring between two points isn't that difficult to resolve.
Which engine do you have?
It's a 3.2 engine.
Firing order is 1-4-3-6-2-5 so if you want to piggyback, connect it to #4.
Have you tested the wiring for cylinder # 3 for battery voltage and continuiyt between injector and PCM?
no, i haven't. I'm not good at electrical stuff. we are just backyard mechanics lol but we swapped coils and we know that the coils are good
we also tested the new injector by connecting it to a battery source and got a spray out of it
At the injector there are two wires. The Dark Green/Light Green wire must have battery voltage when ignition swith is turned on.
The other is a Yellow/White wire which is connected to the PCM, C1 harness connector terminal # 7.
Disconnect the harness connector and probe the terminal with one end of the multitester (set to ohms)and probe the other to the fuel injector Yellow/White, if you have continuity, the problem lies with the PCM.
thank you so much for your help! Sorry it took so long to reply, but just got home. Again thank you. And if you can think of anything else I would deeply appreciate it!
So far the test for the wiring would be the first thing you need to do to confirm that this is not a bad wiring problem.
going to test it this weekend. have to get an ohm's meter first. Hopefully it's in the wiring and i can just run new wire to the injector. if it's not the wiring then i am going to piggy back it until i can afford a new pcm or go to a junk yard and get one. then i'll have to have it programmed.
