the engine is turning but not starting:
repalced spark plugs
tested the following:

1- electrical spark: OK
2- Pressure on fuel line (seems OK), a small valve on the fuel line despenses gas when pushed. Pressue gets built up again, after attempting to crank

How can I test for crank shaft sensor, or what to do next ?

Hello, I'm not sure of the litre size of the engine? With the engine cranking, is there an injector pulse? You really need a fuel pressure gage to check fuel pressure. Right now, I think the crank sensor is ok. It is possible for the ignition module to see the pick-up signal, but, maybe the computer doesn't see it, for some reason. You need to know if the computer sees an rpm signal. Without a scanner, look for injector pulse.

Can you check for codes?
