Is my immobiliser goosed ?

Recommended Posts

MUCH HEAD SCRATCHING ! It died after pressing the horn !!

 

 

This might seem like a wierd one....and take a whle to decribe but...

I've had my 95 2.0 16v on the road for just over a week and all has been fine until today! The alarm+immobiliser which was fitted (serpi star GR420) when I bought it has worked fine , but only sounded, or chirped intermittently when arming / disarming. So today i unplugged the sounder module , sprayed liberally with electrosolve electrical cleaner , let dry and re-fitted..the alarm and siren worked fine , i drove it home from work then back again without problem.

 

Leaving work I pomped at a colleague and...THE ENGINE CUT OUT !!

 

The electrics worked fine , cd , windows , etc. but , when I turned the ignition I didnt get my dash LED's lit up and it wouldn't start ! The immobiliser seemed to arm / disarm , lock / unlock my car but I couldn't start it !!

 

I checked all fuses and relays on the drivers side and all appeared to be sat correctly and the fuses were fine , I could hear a clicking from the passenger side in the engine bay so i removed the glovebox to find the immobiliser itself , along with two more relays #179 and #79 plus two 30A fuses ...I checked that the relays were sat correctly ( they are hanging "loose" possibly to make room for the Immobiliser ) #79 looked to be slightly "out" so i gave it a squeeze in its holder ..turned the key and it started !!!

 

Drove it home , checked horn worked with engine on etc. and all appeared fine so i put the fuse cover and glovebox back thinking it was a cured faulty connection with the relay , left it half an hour or so , went to pick my girlfriend up , pomped outside her house and.....yep... it died !!

 

 

Its started twice since then , after disconnecting and reconnecting the relays , but this may just be coincidence ? The last time it started it ran for approx 10 seconds then died on its own

 

All I get when i turn the key is a click from the engine bay , no dash LED's .

 

It turns over but thats it !

 

Is it a coincidence with the relays ?( #79 and #179 are apparently ABS related ) , Is it a fault with the Immobiliser ? ( did i somehow damage it cleaning the siren )

 

Any help would be great , I apologise for the essay but I wanted to give as accurate a description as possible . I would really love to be able to sort this myself as I can't bear the thought of TOWING it to an auto electrician / garage
