START DIAGNOSING.\u003c\/p\u003e\n\u003cp\u003eEvery mechanic knows this scenario. Customer rolls in: \"My fuel pump isn't priming.\" You pop the underhood fuse box, stare at six identical black relays, and now what? Swap one from the wiper circuit and hope? Order a new $40 OEM relay and pray it fixes it? Or actually find the problem in 30 seconds with the right tool.\u003c\/p\u003e\n\u003cp\u003eThe QuickMech™ Relay Bypass Switch Kit ends the guessing game.\u003c\/p\u003e\n\u003cp\u003e━━━━━━━━━━━━━━━━━━━━━━━━━━\u003cbr\u003e⚡ HOW IT WORKS\u003cbr\u003e━━━━━━━━━━━━━━━━━━━━━━━━━━\u003c\/p\u003e\n\u003cp\u003ePull the suspect relay. Drop in the matching QuickMech™ bypass switch (six sizes included — one will fit). Turn the ignition to RUN. Flip the switch to ON. If the circuit works — the relay was bad. If it still doesn't — your relay is fine, and the fault is elsewhere (wiring, ground, fuse, sensor, or the component itself). Total diagnostic time: under one minute.
