Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.

Expert:  Dan replied 9 months ago.

The engine is flooded.

Expert:  Dan replied 9 months ago.

Remove fuel pump fuse and crank the engine while hold the throttle to the floor.

Expert:  Dan replied 9 months ago.

Crank the engine over for a minute or so then reinstall the fuel pump fuse and it should start. Your plugs could also be fouled. Flooding is a common problem with the renensis.

I've done what you suggested, i.e. the fuel pump fuse removed, etc. No change, it doesn't try to fire at all, on successive days. Is there any chance that, after sitting with a dead battery for a few weeks, that the security system is an issue? The engine spins fine, but never gives any indication of trying to fire. As in no spark or fuel.
