I have a 2004 ford explorer sports trac 3.0 engine motor was replaced now can’t start key is program and work but in theft mode
what happens when you turn the key to start it?
Why was the motor replaced?
did you do the work yourself, or have a shop do it?
Things that will keep an engine from starting:
No fuel, no air, no spark, no power. Have you rechecked wires and connections?
Did you try resetting the security system? If not I suggest you do that and then try starting the engine.
The Explorer Sport-Trac never had a 3.0L, engine. Yours would’ve come with either 4.0L SOHC V6 or a 4.6L V8. Your problem is likely that the PATS is not talking to your donor engine’s ECU, and therefore the command to energize the fuel pump isn’t being made. The ECU will have to programmed to accept your existing PATS code or vice versa. Either way, you’re probably not doing it yourself.
