Hi guys my wife's 05 triubute v6 3.0 litre (right hand drive) came home Friday 2 weeks ago and she called me to look at the pretty lights as she described it on her car, all the warning lights were lit up and had been while she was driving the car, the motor stopped when she put it into park.
After turning the key off and back on no warning lights showing at all except for door open and immobiliser light and no crank of the engine tried a few times turning key on and off and managed a start after this it ran well for a day then when going to go out 2 days later no lights no start, got some second hand bits at wrecker (key and barrel, key reader, pcm, and a relay that is from under the dash near the steering column) after trying the key and reader in car it started on its original key and reader.
Since then it has been sometimes starts sometimes does not last Friday no amount of fiddling would get it to start checked my battery it is old but still holds a good charge, bought a new battery and seemed to fix the issue,i had taken it on a 140km round trip with stopping and starting on last Sunday night no issues.
Boss lady feeling confident it fixed drove about 45 minutes from home stopped a few times last stop would not restart same problem no instrument lights or gauges, in frustration after 40 minutes of fiddling i had loosened the steering column lock as i removed my aftermarket stereo as i had a thought it may be causing an issue (no change), i shook the column up and down a few times suddenly i had instruments and lights.
Drove it home did not dare to stop and top up fuel tank as low fuel light came on 2/3 of the way home, started this morning anticipating looking at wiring and connectors for loose wires or open breaks in lines i cannot see anything and now will not start again no matter how much i move the wiring harness.
BTW gearbox replaced at easter, alternator about 3 weeks later.
Does anyone have a decent wiring diagram of the ignition switch and where the wires go to
May Thanks for any input

 

Solution found
The whole ongoing problem was the fuse box, it is 2 printed circuits face to face with an insulator between them and diodes, resistors and what looks like a self contained microprocessor on it when it is removed from its plastic housing, power was going into fuse box from engine junction box but it was not getting past the fuse box to the rest of the car

 

Good old PJB playing up again.

 

Hi, your problem was in the fuse box located in the engine bay or the one on the BCM inside the center console?
Any pictures? Thanks!

 

It is the fuse box located in the left footwell under the a pillar

 

This is the circuit boards out of the plastic casing that they are put into and the black plastic thing is an insulator between the boards
