Car Won't Start After Sitting - Dead Fuel Pump Replacement

Fuel Systemintermediate✓ OP Confirmed

Problem

Car had been sitting for several years and would not start after being driven a short distance and parked. Fuel pump was not delivering fuel to the fuel rail.

Car cranks but will not startNo fuel flowing from disconnected fuel rail line when pump is jumpedNo audible fuel pump noise when jumping FP and +B at diagnostic connectorJumper wire getting very hot when jumping fuel pump (due to pump drawing 4+ amps on thin wire)

Root Cause

Fuel pump failed after the car sat for several years without use. The pump was receiving 12V power but was not running, confirming an internal pump failure rather than an electrical supply issue.
