Did you fill up the spin on secondary filter before you installed it? There is no primer pump on the 602. According to the user manual you have to floor the pedal and crank the engine for a long time to start the car.

If the glow plugs are good then try to crank it again. It takes a while if the filter was not filled. Do not crank for more than 15-20s then stop for a while and crank again.

Good luck.
