03 cavy PCM problems?
Tuesday, July 23, 2013 6:25 PM
I've been trying to figure this out for weeks now my fuel pump will not turn on put power to fuel pump and its fine wires going to fuel pump are fine also my relay only has one power going to it im preatty sure i need two i tested the relay and it clicks on fine i haven't tested for spark but it seems like i have no spark either and i primed fuel pump and still dident start my security light also stays on solid when im cranking i did a trick i heard on a forum and put a 2.2k ohm resistor on these wires going to my ignition was suppoused to bypass the security theft but my light still stays on i had an accident 3 weeks ago not bad changed my hood and headlights was running fine after the accident and then a week later just wouldent start up one morning if anyone can give me any insight on this would be great thanks

I can't say that I have watched my security light while cranking recently so I'm not sure what the status of that is during that time, but I would say you might need to do the passlock relearn. I have not heard the 2.2k ohm resistor trick, what 2 wires did you cross with it? Also, if there is no power to all the relays under the hood, then you have a problem. they are fed directly from the battery.

I put the resistor between black and a yellow wire in series with the black one and dude the pass code lock reset procedure a few times. I do have constant power to relay panel but no signal when i turn my key my fuel pump will not turn on i put straight power to my fuel pump wire and it turns on, i put a power source to the relay and clicks open fine i heard out of the four posts to fuel pump relay 2 have power one constant and one signal i only have the constant.

Well there isn't much that controls your fuel system and starting. Here is the schematics for the fuel system (Click), and the starting system (Click). I think you're going to have to do some digging.
