Immobiliser problem??
« on: October 17, 2014, 05:02:20 PM »
Hello again... After driving over 500 miles without issue in the new (sic) zetec the wife has reported some serious problems. The other day the alarm went off when she went into a shop and now it is sometimes refusing to start (not even coughing) then a few minutes later will start right up without issue. She says the red light on the door goes on and off without flashing. The guy I bought it from said the fob battery needed replacing and I thought the alarm problem might be to do with this so I replaced them. Nothing seems to happen when the buttons are pressed still. The starting problem only began the day after I was fiddling with the key. Could I have somehow interfered with the immobiliser chip?

It's not likely to be the immobiliser chip in the key if it sometimes starts. It sounds more like Relay 109.  See this link in the Frequently Asked Questions for details https://www.fordmpv.com/smf2/ford-galaxy-reference-library/galaxy-mk1-mk2-tdi-version-relay-109/

Thanks, the 109 relay did spring to mind alright. But the door light is behaving normally. Does the light always get effected?

I've only had one Galaxy so most of what I have gleaned has come from the Forums, and I haven't had a problem on mine (yet!)

I don't think a problem with Relay 109 should cause the immobiliser light to flash.  I know (from my experience) that if you switch the ignition off then on again almost immediately that the door LED will flash even if the car still starts.

Ok, replaced the 109 relay. Actually it was a lot easier than shown on the ref library. Maybe it is different for the mk1 but I didn't have to remove trims or nearly as many screws. The engine did start after a couple of coughs and restarted immediately a couple more times thereafter. Time will tell if it was the relay at fault as the problem was intermittent.... Will report back in a couple of weeks ;-)

Okay, scratch what I said about improvement after replacing the 109 relay!! After driving about for a few days, starting on the button each time it has now dumped us in a car park miles from home. Drove about 40 miles and add yet a brief stop will NOT restart. Not even coughing. Is there anything else that could cause this erratic behaviour? Did the fault codes (using win xp as per cable instructions) and nothing significant seemed to appear. Don't have the results with be but recall something like interior sensors and pressure control.

Have you another car key on your keyring?  Another immobiliser chip for another car could interfere. Should have suggested this first really.

If it was blocked from starting by the immobilser it typically fires up, runs for a couple of seconds then cuts out.  It should have also left a fault code in VAG-COM/VCDS-LITE. At least on the MK2's anyway.

I assume it's turning over at a "normal" speed (ie not slowly like when battery gets flat).

Not sure if MK1's have a Battery Junction Box https://www.fordmpv.com/smf2/ford-galaxy-reference-library/battery-junction-boxauxiliary-fuse-box-repair/

Possibly air getting into fuel line because of missing o-rings in filter/leaks - not experienced this myself but read of it.

MK2's have a fuel pump in the tank that typically gives out a "squelch" noise when ignition first turned on.  Pretty sure MK1's don't though.

Yes it does have a second key on the ring - another galaxy key that only operates the drivers door (I assume a new handle was fitted previously). I tried removing this key from the car altogether but this did not seen to have any effect. Had the car rescue out and got towed for the 2nd time this week. After a lot of arsenic around by the roadside it does appear to be a fuel issue after all. The car eventually tried to start and just sputtered. Could see fuel flowing back to the filter and a peek in here revealed that the filter looked empty of fuel.... The return pipe was quite loose where it goes into the filter but the o ring seemed in place. Don't know now if this is a separate issue from what I thought was the 109 relay. If it was a fuel issue I would have assumed that there might be some running issues and 'difficulty' starting - not a complete refusal to fire at all. Anyway, at least I have a lead to follow for now

Have the car running again after the mechanic replaced the fuel filter and fitted a non return valve to the line after the filter. Won't know I guess if this is a separate problem to the one I thouht I'd fixed with the relay. Time will tell if this starting issue is really fixed... Have another long trip on Monday. The motor rescue say they won't come out again because it s an 'ongoing issue'. So fingers crossed

If you've got a 2.3 petrol it won't have a relay 109, the petrols usually suffer from problems with relay 30. Part numbers in this post, and genuine Ford replacements available here.
