After i put the key in the igniton i used to hear the ignition buzz (i dont miss it) but my fuel pump stays on for a full 20 seconds not the standard 2 sec ecm prime. are these 2 related to each other

BTW its 20 seconds to the um... "second" is something getting overridden with the ecu? or do i have a loose wire

 

having same problem myself, and it causes my car not to start as well

 

"possible" culprit could be the switch in the ecm. the ecm is what triggers the pump to prime, shuts it off when no crank is signaled. maybe that switch is sticking. i'd try to find (borrow?) another ecm before i "replace" it, though.
