Big Problems Pls Help

[fgxod]

Guys I asked you once but I'll ask again.

My car will not start it comes up with a error saying system comms fault in a red triangle.

This is becoming very frustrating as no one can fix it. It went away for awhile and now it has come back. Ever since I changed my battery it came back and worse.

Before it would only take 3-5 max to start now it's like 15-20.

Today I nearly lost my sht at it because I was running so late for a meeting and I couldn't start it for like 5 mins.

The worst part about it is if I turn it off for a few minuets it turns on fine but any longer it wount start.

I thought it had something to do with the tune but we tried so many things to fix it but at that stage it wasn't as bad because it would still start on and within 15 mins so it was hard to see if it's fixed.

The last time I cleaned my engine bay with the high pressure hose it seemed to of fixed it...don't ask me why and how I just gave my engine bay a clean while I washed the car so it was like 45'min job and the car started. Over and over again for ages. Then it came back and then went away for awhile.

I spoke to ford and they have no idea what the hell it could be

Any ideas guys

Sounds like a loose/broken wire somewhere. Just a matter of finding it. Good luck.

You spoke to ford but did you get them to check it?? Codes will tell all sounds like a battery/pats/earthing issue

It doesn't come up with a code to check just system comms fault

[bionicxr6t05]

Whos checking the codes, if its saying system comms fault then a U code will be set

Well how can you check the codes your self?

I had a ford check it for when it was there for a diff replacement and they couldent find anything.

Will the sct pick it up?

The problem is there is no engine light it's either it turns on and runs fine or doesnt.

My tuner couldent find anything on the ecu

The SCT will pick up codes, sounds more like a earth problem or the actual computer is farked.

Who's you're tuner FGXOD? There was a similar problem with a forum members car, spent $3000 trying to find the problem and ended up being his computer, replaced it and no probs since. Will try and find thread for you, was not that long ago either.

Is it turning over and not firing? Or turning the key and it's been slow to respond?

Mine started to get slow to start. I dropped it at Pitlane, picked it up the next day, gave them some money, and now it's perfect.

[bionicxr6t05]

Sct wont pick up communication codes

[fgxod]

It's turning over but wount like its not getting fuel or something or like a kill switch.
