RR 1989 3.5 V8 Starting problem

I have a 1989 classic 3.5 v8 and seem to have a problem....
the car was left standing for 3 days and when i went to start her up nothing the starter was moving the electrics where fine fuel was prominent and a spark but not much else....
i have been told in some caases when left on a slight decline in thwe road fuel sometimes leaks into the pistons and the somehow gets past the seals and ends up mixing with the oil and this may be the problem if so i have been told to squirt oil into the pistons to create a seal and replace the sparks once running i'm to then empty the oil sump and replace the oil as it is mixing with fuel...please can someone let me know if this is true and if not where my problem lies

I dont particulary agree with the possible cause of your problem however it would not be uncommon for a V8 to flood.
Im presuming that your vehicle is EFI due to the age?

The theory that you have written usually gets them going if they are flooded.

Was the vehicle moved a short distance before it was turned off last?

Drove it about 20 miles

also if it is a flood how can i stop it in the future???

Providing they are not started then stopped quickly when cold, the most probable cause is a sensor fault such as a temp sensor. Also check the cold start injector as sometimes these can stick open.
