Engine lubrication on starting.
Discussion
Well, some of my thoughts.....
Most threads on here relate to poor starting, I kinda have the opposite for cold starting. I show the ignition barrel the key and it starts. when started the engine is immediately at circa 1500 RPM.
My problem is the car may be sat for a week not being used this means that all the oil slowly drains from every orifice.
I would like to prime the car with oil off the starter for a few seconds, has anyone added a 12v delay timer into the circuit that cuts in after a matter of seconds?
I was thinking of making this switchable for hot starting.
Any thoughts?

I was thinking the same thing but have a more "manual" solution. I am planning to add a small switch below the dash to cut the LT feed to the coil. Switch it off and crank the engine for a few seconds before letting it start. Bonus is that the switch acts as a (very) crude security device. I did something similar to my Triumph Spitfire in the mid 80s to stop my university friends from "borrowing" it 
Coming at the problem from the other end, Slick-50 oil additive with teflon was designed for exactly this situation, giving protection to metal surfaces when the oil has drained away.
I saw a demo at a motor show in the late 70s when the product was launched. During development, after treating an engine they drained all the oil and then drove the car across an Australian desert, without overheating. This test was later successfully duplicated by independent US authorities.
The original Slick-50 treatment coated all the moving parts with teflon, so an oil-change did not remove the benefits. But the current manufacturers are not using the original formula, and their claims have been discredited. The original 1970s formula, which was proven to work in US Government tests, is now marketed as "Xcelplus", available on Ebay and direct from their website.

Nicely done, your method is the ultimate solution
Yes it's been done by many but don't know how many
Well, actually the ultimate solution would be an electric oil pump that brought pressure up before the crank revolves.Yes it's been done by many but don't know how many
Wonder if it has ever been done.

This
it is then
You can (at not inconsiderable expense) obtain a 'pre-oiler', a mechanically pressurised oil accumulator which releases its charge through the lubrication system upon request. Through an electrically operated valve, pressurised oil from the lubrication system is fed into a spring-loaded chamber when the engine is running, and later, prior to the next start-up, released back through the same valve into the oilways to flood all the bearings.
Used mainly on very precious machinery.
Here you go, called an 'Accusump':

Wow this is clever, found more here https://www.merlinmotorsport.co.uk/knowledge_base_...
It's not often that an advert for such a good looking product shows crush-on connectors

Hmm, you could Interrupt the + feed to the coil with a 2 pin normally open oil pressure safety switch. That way it'll crank until pressure has built up, then fire up
If the engine takes a while to build oil pressure , fuel mght flood it though. If its fuel injection you could kill the power to the pump with the same method instead.

No, not a "great find". That is the discreditation of the CURRENT formula, sold as Slick-50, which I already mentioned. If you read the link I provided for the manufacturer of Xcelplus, they also explain that they are using the original formula which does work, and the website contains links to independent US tests which back up their claims.

I rigged a circuit that only energised the fuel injection relay once the oil pressure was over 5 psi for my occasionally driven MR2.
Unfortunately, as far as I could tell the ECU decided that the engine must be flooded after cranking without firing, and turned off the fuel injectors for a while.
It took quite a while after my cutoff was disengaged before it would actually start.

Who'd have thought that could happen
Not sure what people are trying to "correct" or edit here ...
The original 1970s formula is still made, but by a different company and not marketed as Slick-50 as it used to be. The current formula, which IS sold as Slick-50, is the one that failed to meet its claims when independently tested.
