Lately after my car sits for a few weeks it will start instantly,its a little unnerving considering the oil hasn't has a chance to pump up.Marc H says its nothing to worry about so I guess its no big deal just cant understand why all of the sudden its doing this.My first thought was a leaky fuel injector.

Honestly, it may be timing and compression just by the luck of the draw, so to speak, as the motor is shut off. This happens to me regularly enough.

Yes, it kinda takes you by surprise. I don't like it because I always like a longer cranking time in order to get some oil to the top of the heads, even though I have the check valve in the oil filter. And when this instant start happens, it always seems that the rpms are high initially, as well.

I spoke to both Pete and Marc about it and was told not to be concerned.

I also studied the old Lotus engine build data that I have. Their data showed 5 seconds to build oil pressure upon start-up. This was only one example.

Its a little odd that this would just start happening now after having the car for awhile now.Something else to take into account twice now in the last couple off months for a few seconds the car wasnt running on all cylinders,felt like it fouled a plug but it cleared up,straightened out.Might be an injector going South.Ive got a Haibeck chip and I was under the impression that a touch of extra crank time was programmed into the chip.Oh well,if those in the know said its not a problem,thats all I need to know.
