NHTSA Complaint #11667940 — 2003 HONDA PILOT

Reporting an important safety issue I experienced due to random engine stalling on my 2003 Honda Pilot, typically after driving for a few minutes. The engine would crank for several seconds or sometimes start immediately after stalling, but no diagnostic trouble codes were ever stored. The vehicle had stable fuel trims and idle, and multiple components including the EGR valve and valve clearance were serviced without resolving the issue. Ultimately, the root cause was traced to a failing PGM-FI (fuel pump) relay located under the driver’s dash. After replacing the relay close to two months ago, the stalling stopped completely. This issue could pose a safety risk if the engine stalls in traffic, especially in a hazardous area where there’s no breakdown lane (construction zone, etc.) , and I believe this factor should consider this a known failure point in aging vehicles of this model. Attached are two images of the new relay zip tied under the driver’s footwell (could not remove the bad relay since it was too difficult to remove from its bracket).
