Did you check the firing order? Also, check the gas at the injectors, there is a filter on the main hose entering the flowmeter, it can mislead you. If you are getting it at the injectors, it isnt a fuel problem.

Next, I would check the OVP relay, behind the battery. It has a 1O amp fuse.

I would install new Bosch Super plugs, make sure you set the gap correctly.

Check this and let me know.
