Volvo 2,3L Penta won't start after change of timingbelt, the old one was
broken.
The belt have three marks, one for each sprocket (camshaft, distributor and
crankshaft), so the job should be a piece of cake :-) Let me add up what we
do:
1. Adjust the crankshaft, camshaft and distributor merging the marks on the
belt pullies and engine block.
2. Assemble the belt, with all the three marks fitting the marks on the
pullies.

In this position the piston no. 1 and 4 are on top, the ignition distributor
points on no. 4, so I belive no. 4 should fire in position. But it won't.

Are you sure that you are bring the engine to TDC, number 1 cylinder
firing?

You probably havent installed the spark plug wires correctly, when all marks
align you should have spark at cylinder 1.
No 1. is the cylinder closest to the cambelt.

No 1 is at the front of the engine no 4 is at the rear. Check on Turbobricks
for ignition lead diagram that you have the right lead going to the right
plug. If the leads do not go to the correct plugs you are likely to have the
timing 180degrees out and a no run condition.

All the best, Peter.

All marks lines up just like that, but distributor points at no. 4.

Leave the marks as they are. Pull the distributor, turn the rotor 180*
and reinstall.
