Car cranks but will not fire up

[jondee86]

Your mate should have checked/set the cam timing first, and then set
the ignition timing. How much fuel won't make any difference, so long
as there are a few litres in the tank. But how much fuel is in the cylinder
after prolonged cranking does matter !!

If the plugs are wet with a film of fuel, they most likely won't spark. You
need to have a spare (clean/dry) set to swap in. But before you do that,
while the plugs are out, pull the fuel injection fuses to stop the injectors
firing, and crank the engine for 20-30 seconds to clear some of the fuel
from the cylinders. Take the plug off the cold start injector while you are
doing this, but remember to put it back on when you replace the fuses
and fit the fresh plugs.

Wind the idle air adjustment screw (down the tube on the side of the
throttlebody) out a couple of turns to make sure there is enough air
getting into the engine... cross your fingers... and crank :E
