Most strange, started up, drove down the road 100 yards, and the everything just switches off..

 

Pulled over (obviously), and no sign of stack / fuel pump or anything else giving signs of life.. Lights still work, as does alarm, so battery and connections appear good.. Key does nothing.

 

I presume its a connector / relay / fuse somewhere... (hopes)?

 

Cheers,

Ross

1. Try your spare key first.

2. Press fuel cut off switch.

3. Remove fuse 8 for 5 min.

4. Verify battery + not touching chassis. 

 

After that, it get´s more serious.

Cheers Smiley, good list..

Are you SC? If so make sure your alternator isn't shorting out on the inlet manifold.... Check ecu plug connections are not wet.

[JimmyJamJerusalem]

Is it intermittent or terminal?

[LY_Scott]

He is.

[Rosssco]

Jimmy, its currently terminal, only happened once so far.. I had to leave it and go to work.

 

I'll check the alternator connection, but I've made this mistake before, and in that circumstance the battery started shorting, which has not happended this time. The battery seems ok as there is still power to ancillary systems. I'll check ECU plugs. Been getting dead throttle syndrome recently, but sprayed the x2/3 connectors behind the header tank and that seemed to have cured it for the time being. Wonder if it could be related..

 

Or maybe this is a sign that my car really wants that LSJ engine upgrade after all..

If it´s going down that route again, ty down the cables to the bracket after respraying the connectors.
That will help in them moving less, thus less chance of shorting.

Will keep that in mind Smiley, thanks. Well, done all of the above to no avail... However, I did check fuse 7 (ignition services -10A) and it was popped. Replaced it and the dash flickered as if about to start then popped again. Tried another 3 fuses and the same result of dead fuses... So, what would be causing it to continually pop fuses? I'll get some more tomo and give it another go Never tried a higher rated fuse, because I guessed it was rated as such for a reason..

Fuse 7 controls a lot, including an ecu connections and the starter relay...

You have a ground shortage somewhere, so start checking that FB7 list...

(maybe your handbrake damaged the cable that runs right next to it?)

[JimmyJamJerusalem]

Do you have a multimeter? Sounds like something is shorting to earth. Where are you based?

[Arno]

Engine-to-chassis main ground strap broken/fractured?

 

Bye, Arno.

[Rosssco]

Cheers for the advise, I'll check some of these tonight..

 

Curious, I note fuse 7 is related to the radio / headunit, and I changed this just the night before this happened. Given the gaggle of wires in there, I could have easily broken / damaged one as I pushed the head unit in.. Worth a check tonight I think.

[JimmyJamJerusalem]

Yeah defo mate if that intervention was immediately before the issue manifested then start there

[peteslag]

This could be a short to earth or a line to line short.  A good way to fault find is to set a multimeter to resistance, connect the black lead to a good earthing point on the chasis and the red lead into the circuit side of the fuse holder.  At this point a short to earth will give you a low reading (hence why your current is too high).  Then remove the head unit, if the problem is behind the stereo this will more than likely remove the short to earth and give you a much higher reading on the multimeter. If this happens you can then have a good look inside the dash and hopefully the culprit will present itself.  If not, PM me.  I have a wealth of electrical and electronic fault finding experience and I'm more than happy to help.   

[JimmyJamJerusalem]

Any joy bud?

[Rosssco]

Well, thanks for the help on this. Took the replacement head unit out, and there was a loose exposed wire coming from the loom - perfect for shorting out under the dash. Pulled it off, replaced the fuse and it runs! Looks like this was what was happening (fingers crossed).. Ross

[JimmyJamJerusalem]

Glad you got it sorted

I never got to find one cause for this, I checked the steering wheel and could find nothing, I did find that my loom had a load of cut wires where the extra ecu for the 5th injector was, these were just cut. Also he injector wiring was loose as it would run rough when I moved the loom near the injectors. Sadly was this the cause??????

 

Hope you find it though it did drive me mad worrying was it going to cut out,
