I have done the following:
Fuel pump has the "hum" that proves its working.
Replaced the coil and module as I didn't have a spark at the coil.
For testing, removed fuel filter and substituted it for a short length of hose and clamps to rule out a filter problem, no help..
Checked the fuse box and noticed that one 30A fuse was blown, "AUX" fuse, so I swapped it with another. Didn't help.
I probed around with the Goodwrench alarm system box but couldn't detect a problem there. The start relay in the box has the audible click when energized.

FWI....the fuel pressure regulator was replaced at 150,000 miles.

any suggestions and remedies are greatly appreciated.

Whats the fuel pressure? Just because it "hums" doesn't mean it has enough pressure to start.
