WHY WON'T IT START?

1996 Pontiac Grand Am • 120,000 miles

Car has been running well. Parked it and came out the next morning and engine would crank over, but would not start. Have determined that engine is lacking spark and fuel. Upon key on, I hear the fuel pump run, along with everything else powering up ok. All fuses ok, including the pcm and ign fuse. Have replaced the coil pack along with the ignition module and crank sensor, but with no change. Ignition module getting the 12 volts at the 2 pin conn. On left side. Crank sensor ohmed out at 901 and with engine cranking was getting 1.1 volts. All grounds look good. Unplugged map sensor, no change.
Wondering what to look at next?

Yes, same key. Theft light has always been on

It really sounds like a pass- key or pass lock issue to me. Can you have someone scan it and see what kind of theft system codes you have

Checked power, cleaned and rest. Only codes where for the oxygen sensor. Still nothing

Christinate, did you tell them you needed soft/theft system codes pulled?
