nope, the flashing oil can is oil pressure and if the engine isn't running neither will the oil pump. a joint / junction which is poor when cold can often improve when warm due to slight expansion / drying out sort of things. the problem is quite common but not one applicable to my old VR so my help can only be limited. Have a look through the electrical problems section, or wait for somebody with more knowledge/experience to come along. One drastic solution is to have Stealth or United Motorsport, or whatever Matt is now trading as, remove the immob function from the ECU.
