Unhappy B2300 Crank but wonít start

I have a 2003 B2300. It cranks but does not start. I replaced the fuel pump and checked and it has fuel pressure. Scanned it and the only code was P2004 IMCM (Intake Manifold Control Module), I also change that part. Check the Inertia Switch, its perfect. Checked the sparks and it has spark. Iím running out of options. If Anyone knows something at least a clue please help.

Realize that your Mazda truck (1994 and newer) is really a Ford Ranger. That said: I'm way more familiar with 1986-1993 Mazda trucks, so don't even know if your truck has a rubber timing belt or a metal timing chain, but here goes.

Get some aerosol starting fluid (Walmart, O'Reilly, etc.). Spray some into the air intake and try to start (pedal to the floor), do this several times if necessary. If the engine starts, even rough, for a few seconds then dies, then you have a fuel delivery issue, even though you replaced some fuel-related parts already. If it doesn't start after trying aerosol starting fluid, then one must suspect spark (you say you have spark), like is that spark at correct time (timing belt/chain slipped or broken), bad compression, etc.

Did this failure to start happen suddenly, or was it something that just kept getting worse?
