2006 Toyota Corolla wont start

Hi, I seem to have the same problem with my Corolla verso 2004. The steering lock doesn't disengage and the car won't start even though the immobiliser light stops flashing. Have you managed to get it sorted?
Thanks

***** Update**** In the end I did manage to get my problem fixed. It had nothing to do with the key. The problem was a faulty connection in the immobiliser motor that sits on the steering column, It wouldn't disengage. Our mechanic checked and repaired the motor and now the car works fine. It's a very rare fault apparently.

The head must be torqued properly. If is probably warped and needs replacing.

Vacuume leak is very probabe, check vacuum hoses for leaks, gasket leak at intake manifold or throttle body etc. I like to use starting fluid and spray around a bit. If you spray it on a vacuum leak, your rpms will noticably go up.

They only have 2 bolts holding them in. Unbolt/unclip the wires from the starter and then remove those 2 bolts. Replacing it is the same process in reverse.

Check power is coming out of your exiter wire ,the little single spade terminal that plugs on to your starter,if not maybe a faulty ignition switch or damaged loom.

The problem is the rear motor mount is filled with hydraulic fluid that leaks onto the accessory drive belt. The motor mounts fail prematurely and the fluid makes the belt squeak. Toyota dealership I took my 2006 Corolla to replaced the motor mount and belt free of charge.

plz tell me about O D

remove the resavoir bottle and clean it all out

try proper jump leads ,not cheap chinese ones ,then start slave car and leave running for 10 mins before trying it ,if it still will not start call dealer because immobilisor has cut in which is a dealer only job because of encrypted software

You need to isolate the problem. If it starts when you spray carb cleaner into the throttle body while cranking then problem is in fuel system.(pump, pump relay, filter or fuse) If not, then look into ignition system. Use any manual to get specific testing instructions and do not buy anything till you verify by testing that you really need that part or it can get unnecessarily expensive.
If you need more info on anything, just ask, but at the point you are at, careful testing will tell you far more than anyone here can tell you.
