1. Don't try starting the engine just yet. Dont try forcing clutch pedal down.
2. Change engine oil and filter ( 8 years outside unused will have produced a lot of condensation/ water in the oil )
3. Remove ignition coils and spark plugs , plugs will be corroded / fouled . Carefully clean the electrodes or buy new set.
4 . Put a small amount of engine oil ( about a teaspoon) into each cylinder through the spark plug holes.
5 Leave oil .
6. Fit a new battery. Using a jump is a waste of time on a car that has been standing this long.
7. Leaving out the plugs ( rest coils on inlet manifold or cam cover).
8 . You need to now crank the engine over to build oil pressure . Crank engine over for say 10 times in 2/3 second bursts.
9. If it all sounds smooth enough, next thing is to fit plugs and try starting it.
10. In complete quietness turn on ignition and listen if fuel pump primes for about one second. ( sound will come from under back seat area).
11. Try cranking . It might start.
12. If no fuel pump run , lay down next to car and thump fuel tank hard with palm of your hand while someone cranks engine over. Pumps often stick when left for years unused. Vibrating the tank usually overcomes this.
13. If engine runs beware seized auxiliary belt components. Squeeling / smoke coming up from belt area will warn you of any problems.
All of the above takes no account of the cam belt condition , which is way way beyond its replacement time.
If the cam belt breaks , don't blame me . You have no choice really unless you want to do a cam belt change before any of the above.
Ideal scenario would be engine starts with no rude noises . Idle speed may be all over the place for quite some time as ecu will need to do a re learn of throttle idle setting.
Heat and vibration from engine running may , if you're very lucky free the clutch release bearing which may be your clutch problem. Be very gentle with clutch pedal until it shows signs of freeing .
Be be prepared to fit new discs pads and calipers all round .... 8 years outside will kill all of these .
Exhaust , if not stainless will also probably need attention.
