Ok, I need some help. I have searched for a while an not found the answer. I have an '01 GS300, no engine mods. Turn the key all lights ok, starter turns over strong....no ignition??? Changed the battery, no better. Changed the crank positon sensor, no better. Fuel pump working, but no spark and no pulse on the injectors. No check engine light other than the usual with the ignition in the on position and no codes in the OBDII. Here is another catch, sometimes it starts, not easily but it start after lots of cranking. Most reliable way to get it started is let it sit for a long while then jump it, still doesn't start easily. My start asst on my charger works best. So I ruled out the starter/solenoid. The crank sensor and battery, of course. Fuel pump and plugs, since it does still run occasionally.

A couple of things I have thought about: Starter disable from the security system? Could it be a low battery in the key fob? BTW my driver door actuator won't lock, not sure if that has anything to do with it, but that has gone on for about a month and I see lots of posts about that.


HELP!
