Guest Oddjobber23 Posted June 12, 2016 Share Posted June 12, 2016 Hello, I finally managed to find a nice, prime for restoration mk5 xr3i that was sold with a possible immobiliser problem. It has baffled my son who is a mechanic so I am searching for any help or whether I should give up. It is a 1992 16v 1.8 and when the key is turned nothing happens, no lights on the dash no turning of the starter no anything. All I have noticed is a single click that appears to be coming from near the ignition barrel. I have contacted my local auto electrical business and they have given me no hope. I have read that sometimes it turns out to be the fuse box but the only replacement I have found is in America at £300 delivered. If anyone can help it would be great because I have been searching for one of these for awhile now and really do not want to send it to the bone yard. Many thanks, Alan Quote Link to comment Share on other sites More sharing options...
Ian71 Posted June 12, 2016 Share Posted June 12, 2016 Fuse boards on mk5 seems to be a common problem. Advice is to remove and re-solder bad joints,a few peeps on here have done this. Quote Link to comment Share on other sites More sharing options...
Guest Oddjobber23 Posted June 12, 2016 Share Posted June 12, 2016 Hello, thanks for that. I will be trying to source a more reasonably priced box and keep my fingers crossed that it is that. Alan Quote Link to comment Share on other sites More sharing options...
Ian71 Posted June 12, 2016 Share Posted June 12, 2016 Seems strange that an auto electrician can't test a few circuits to pinpoint the problem Quote Link to comment Share on other sites More sharing options...
Ian71 Posted June 12, 2016 Share Posted June 12, 2016 go to ebay no 360867906830 and read what it says about fuse box numbers. Quote Link to comment Share on other sites More sharing options...
gingergman Posted June 12, 2016 Share Posted June 12, 2016 id get a decent auto electrician to give it the once over, save the headaches and guessing games. recently had one look at my mk4, saved me so much aggro! Quote Link to comment Share on other sites More sharing options...
Guest Oddjobber23 Posted June 13, 2016 Share Posted June 13, 2016 Hello, I have managed to source a refurbished fuse box that matches the numbers for my car.The auto electrician round here need me to take it to their base. I thank you all for your input. Alan Quote Link to comment Share on other sites More sharing options...
Guest Oddjobber23 Posted June 20, 2016 Share Posted June 20, 2016 New fusebox sourced and fitted , great. Now the car turns over but refuses to start just keeps turning over. It doesn't even try to start. I do not know if it is relevant but the little red light is constantly on. Please help as I want this to work as it has taken quite a while to find a viable project in my price range. All the best, Alan Quote Link to comment Share on other sites More sharing options...
Ian71 Posted June 20, 2016 Share Posted June 20, 2016 Have you tested to see if you have any spark on your sparkplugs. Remove one keep the lead attached ,get someone to turn the ignition over while you watch the spark plug to see if its sparking. If no spark then its electrical. If you have a spark then it has to be fuel,prob the fuel pump. Quote Link to comment Share on other sites More sharing options...
Guest Oddjobber23 Posted June 21, 2016 Share Posted June 21, 2016 Hi, there is no spark but also there doesn't appear to be any fuel, or I cannot smell any petrol from around the engine that would usually be present after turning the engine over and over as has been done.

Guest username Posted June 21, 2016 Share Posted June 21, 2016 (edited) if the red immobiliser light is on when trying to start then the immobiliser is set and the ECU won't allow fuel or spark. If it's pre "PATS", try locking/unlocking the doors with the key and then try to start (if it doesn't work when you do it via drivers door, try lock/unlock the passenger side in case the switch in the lock is faulty).

Vincygav Posted June 28, 2016 Share Posted June 28, 2016 Also make sure the fuel pump wire is connected to the battery. It is easy to forget this and IIRC would also make the red immobiliser light come on. Quote Link to comment Share on other sites More sharing options...
