09 f150 missing ecm
bought a 2009 f150 from tx dot . they keep there vehicles up very well. i bought as inoperable , ecm was missing. no records available. 240k miles. i bought a junkyard ecm that matched the 5.4 3v engine. only code after installation was p1622 pats mismatch.no crank no start. security light flashes. i can jump the relay and crank the engine. question is since i have not heard this engine run how much money should i spend to program the ecm to match the vin. and if i do that then pay a locksmith to program the pats. ?? or what do any of you suggest. thanks.

You can do this with Forscan and 1 hour of reading/research. See the Forscan topics in this forum. You will save $$ and have a scan tool to use on your project truck.

Here is one forum discussion. It does not explain how to input the VIN in Hex format but it does have some good info from one of the Forscan gurus.
