GMC Yukon Fuel Pump Relay Replacement at your home or office.

Good

Inspection and Diagnostic Was 100% wrong. On all parts. Problem: All Rear lights flickering Inspection: Diagnostic: Turn signal, tail lights bad connections Repair Signal and connections recommendations: Remove and Replace Multi functional turn signal switch. also has bad connection between turn signal and tail lights. Replace Rear lamp harness connectors. L&R side. All diagnostic and recommendations Was accurately completed. That cost my son, greatly in unnecessary repair cost. That didn't fix the problem or anything else. and didn't need to be replaced or fixed, still had power to the replaced parts and in good working order. Following the recommended repairs ended up adding additional problems, truck remote and driverside door. Has lost all control functions and alarm has to be set manually and individually. False warning lights and codes popping up. Preventing from addressing real problem, until to late and check engine pressure light comes on and knocking noise from engine appears, after addressing and clearing of warning lights and codes. That had already been fixed or was a wrong random code that needed no action to be taken. I asked a repair forum and explained in detail. And Jacob recommended I start from troubleshooting from the simplest solution and make my way up if necessary. First obviously, check the brake lamp bulbs are correct and there was power to the build and sockets. Check. Next make sure the ground connection by the rear hitch wasn't broken or damaged while the brake light bulbs was being removed and replaced. And we have a winner. The ground connection. Fixed all rear lights. They're working normal again. A $0 fix cost my son over $800 in parts and labor fees. And now a motor. New Battery, New O2 sensors up/ down replaced, ignition coils and wires replaced, spark plugs, oil change, oil gasket replacement, filters. Valve Cover Gasket replaced. No leaks anywhere. Replaced the recommended, set off false codes. After getting it reset. Check oil pressure light comes on and knocking noises occur. Next day motor is needed. All could had been prevented if the obvious connection test was performed. I would recommend yourmechanic.com. I have a appt scheduled. Pay attention to the mechanic. Cost my self paying college son a vehicle.
