Where Is The Mercedes GL550 Fuel Pump Relay Located?
Trying to find the Mercedes GL550 fuel pump relay? This is something most owners deal with at some point. On many GL550s, Mercedes stashes it inside the main fuse and relay box. Open the hood and look near the passenger-side fender—you’ll usually see a black plastic box. Pop the cover, scan the diagram under the lid, and you should spot the fuel pump relay position. If it’s not there, check the rear fuse box; a few model years put it in back. Owners’ manuals are not much fun to read but they’re useful here. No start, or silence from the pump? That relay is often the first thing to check out.
What Are The Symptoms Of A Bad Mercedes GL550 Fuel Pump Relay?
A failing Mercedes GL550 fuel pump relay throws a few clear red flags. You might turn the key and the engine just cranks and cranks, but never catches. Sometimes, it will run for days and then out of nowhere, refuse to start. Maybe it stalls out after starting, usually in the most inconvenient spot. One day, you get in and everything’s dead silent: no hum from the fuel pump, maybe a faint ticking near the fuse box. The car waits it out, then fires up again—until it doesn’t. Any of these could be your relay begging for help.
How Do You Test The Mercedes GL550 Fuel Pump Relay?
Testing the Mercedes GL550 fuel pump relay isn’t complicated if you know your way around a fuse box. Try swapping it with another matching relay from the box; if the car starts, swap successful and the original relay is probably toast. For a closer look, grab a multimeter. With everything off and the battery disconnected, pull the relay, set your meter to ‘beep’ or ‘continuity’, and check the pins. Turn the key on, check for voltage where there should be power. Mismatched numbers? You’re looking at a failed relay. Always disconnect the battery first or you could give yourself a nasty shock.
Can I Drive With A Bad Mercedes GL550 Fuel Pump Relay?
Tempted to risk it with a spotty Mercedes GL550 fuel pump relay? That’s a gamble—when the relay goes, so does the fuel pump, and without fuel, you’re not getting far. Sometimes the car dies in traffic. Sometimes it refuses to start in the morning. Neither is a good time. Even if it works for now, you never know when it’ll let you down. Don’t chance it. Change the relay before it strands you or, worse, puts you on the side of the road.
How Much Does It Cost To Replace The Mercedes GL550 Fuel Pump Relay?
Good news: replacing the Mercedes GL550 fuel pump relay won’t empty your wallet. Parts are usually $20 to $60—sometimes less, sometimes a hair more if you buy dealer. Labor falls between $50 and $120 at most shops. But the job is simple enough for many DIYers: pull the old relay, snap in the new one, button everything up. Beats a tow any day, and one less thing to worry about.
