the key code light on my 146 ts dash board is staying on.the car turns over but will not start any advice?i also have the card with elec code and machanical code.
Did it once work with the key?
Could be the immobiliser thingy. A black rectangler thing in the car key that tells the car that the key is for the car and that the car should start. Sorry, not technical terms but there you go and worth a look. Check if it's dislodged or not close enough to the dash when turning it.
do you have any more details on the car, age, engine size etc, may be relevant.
The first thing to check is the relays infront of the battery, there are 4 on an alloy topped car and two on cars with the plastic engine cover. One of these operated the CODE circuit (along with other things) and they often get covered in water and corrode, take them out carefully and clean up with emery cloth. Ensure all the wires are in place as they car become brittle over time, a wire snaps and your car does not start.
Just to add to the advice on the relays in front of the battery. Make sure you clean the spade connectors on the relays/fuses and also in the holders themselves really well (actually remove the captive connectors from the holders to clean them). Use something like scotchbrite to clean off any oxidation/corrosion, then tighten up the spade connector grip using some pliers (squeeze them closed a bit more), then smear a liberal amount of electrical contact grease on them.
We've seen in the past that people do a "clean-up" the connections in the relay/fuse box but do a half-hearted effort and still end up with problem. A second attempt then sometimes resolves the problem. So, it's well worth spending the extra time cleaning everything up properly the first time round
THANKS PURPLE 145 the car is at plate(1999) and has 4200 miles on clock it has been stood scince sept last year but has started ever time firs time until two weeks ago.the reason why it has been stood is due to women drivers.haha!please help!arghh
OK, so you have two relays around the battery, so they need checking.
Do you have a master key, a square burgandy one rather than the bright red every day key? That normally sorts out CODE issues. POp in the ignition, turn so the ignition is on, wait a few seconds, see if the CODE light goes out and try to start.
Let us know how you get on. BTW, has the cambelt been done yet, should be done at 36000 miles, 9 years is pushing it as the rubber can perish.
