Any gas in the tank?

How about spark?

What engine?

Why did you replace the engine?

Where do you have #1 clocked at in the distributor?

Is the battery good and fully charged up?

I have checked every sensor and went to the dealership to check the
coil to make sure it was firing properly. The coil fires within specs
on the primary and secondary outputs. Went through and checked and
triple checked every connection and vacuum line. And (LOL) I did make
sure the rotor was in the distributor. Made sure we were had the wires
on the cap right. I can recite the firing order in my sleep mow. If I
had hair to pull out I would. I think the problem is a simple one its
just driving me nuts!!!

Are you sure it's getting fuel? Do you hear the fuel pump when the
ignition is switched on? Is there fuel at the injectors? Are the
injectors plugged in? (I know but often it's the stupid stuff that
trips us up!)

Are the spark plugs actually getting spark? I know of a guy who went
through this and it turned out the contact in the center of the
distributor cap had fallen out.
