Hello all. New member here. I have a 98 Pathfinder, and recently it fried the part of the ECM that controls the fuel injectors. I want to replace the ecm and have found one on ebay for under $100. The question I have is do I have to reprogram, or reset. It does not have keyless entry, or at least I don't have a key fob for keyless. Any input would be appreciated.

As long as it's an ECU out of a 98 or similar model and an automatic transmission model it should work just fine. If yours is a manual transmission model you should be fine with whatever ECU you get.

 

Keyless entry is handled by a separate unit entirely so no worries there.

 

Once you get a new one I'd still clear it with a scan tool just in case the previous vehicle has stored any codes.
