Engine turns over but no spark how can I solve that?

I think you need to look at the ignition coil, follow the wire that goes into the center of the distributor cap, that will be your ignition coil or module.

New spark plugs!

The mass airflow box has a flap in it that works like an inertia switch, I had the same issue with my truck and I checked the whole wiring system. You pull the lid off the air box, unbolt the sensor from the lid and then separate the sensor, I cleaned the flap and got it moving free and clear put it all back together and it fired up in two seconds.
