Why does your Mazda b2200 not start after you replaced the water pump?

Simple answer for this.If the truck turns over and over and does not fire the most likely cause is the timing is set properly.If you had the camshaft on A lined up with the pointer and the crankshaft lined centered with the pointer in as close to dead center the timing should have been correct.This sohc engine is very easy and forgiving.I would check the timing and make sure with a timing light that on the crankshaft the first notch is AT TOP DEAD CENTER which goes towards the alternator,next the big notch in the middle is TOP DEAD CENTER and the small notch to the right (going towards the pwr steering is BEFORE TOP DEAD CENTER.The mark you want it set on is 6"degrees btdc.Mark this with paint use yellow for atdc and white for the small btdc.When setting the timing you want the timing between the yellow and white.Unless you have a plug wire disconnected or coil wire on the distributor cap is loose I have no idea.
