Where Is The Mercedes Cl550 Fuel Pump Relay Located?
If you’re hunting for the Mercedes CL550 fuel pump relay, pop the trunk and look on the right side under the carpet or trim. There’s a fuse box back there. It usually hides under a cover, along with a bunch of other relays. The trick is to check the fuse chart—either on the lid or in your manual—for the right spot. Expect to move some panels or lift up the floor mat. You might need a flashlight and some patience since the relays aren’t always easy to spot on the first try. Matching up the diagram before you start unplugging things helps avoid mistakes.
What Are Signs Of A Bad Mercedes Cl550 Fuel Pump Relay?
Wondering if your Mercedes CL550 fuel pump relay is acting up? Sometimes, the car cranks but stays quiet and refuses to catch. Maybe it’ll start, then stall out after a little while. You might hear nothing from the fuel pump when you turn the key to “on.” Some days it’ll work, but let the engine heat up, and no luck. It’s a pain when the issue is hit-or-miss. Try checking that relay first before throwing money at other repairs. That one small part often causes big headaches without warning.
How Do You Test The Mercedes Cl550 Fuel Pump Relay?
To see if the Mercedes CL550 fuel pump relay is the problem, grab a multimeter. You’ll need to check for continuity on each pin using the wiring diagram. Pull the relay from its slot, then touch the probes to the proper contacts. Turn the key to the "run" position and listen—no click usually means trouble. If you have a similar relay in another slot (like for the horn), swap them for a quick test. If the fuel pump kicks on, you’ve found your answer. This approach often saves time and cash.
Can You Drive With A Faulty Mercedes Cl550 Fuel Pump Relay?

Waiting can leave you stranded or worse.
