Why wont my car still start?

I have a 1999 oldsmobile alero I just replaced the ecu box and ignition . The security light finally stopped blinking and the doors chime again and the trunk opens again but it still won't start. When trying to start it it does turn off like it did before switch parts now it seems like there is no gas or battery no juice but there is gas and battery good. Why won't it start still?

There is gas in the gas line to the injectors. Is it suppose to be under pressure or weak when push on gas rail?

door

Yes, there should be pressure with fuel spraying out when ignition is turned on. Presuming the fuel pump is working with pressure on the fuel rail, this doesn't tell you if injectors are operating. After several starting attempts, spark plugs should be wet with fuel to indicate injectors are operating.

Is this Passlock security? The bcm and ecm have a security password that requires 'marrying' each other thru a procedure. Dealers use their scantool to marry these components in 10 minutes. Diyers without GMs scantool must perform three 10 minute ignition on cycles to marry these components. The ignition switch contains an embedded resistor that's learned in this procedure before security allows normal starting. GM may disable injectors when a theft attempt or security parts are replaced without a relearn (marrying) procedure. Passlock security flashing indicates either a theft attempt or relearn not performed to turn it off. If off during starting then verify spark and removing a spark plug to smell it for gasoline. And check for blwon fuses.
