Two fun ones in a row,
2005 F-150 no start another shop installed a fuel Pump relay mod, They forgot to snap the connector on the module. Guy made it far enough to get a tow truck to pull it here.
2016 6.7 guy had another shop install a triton oversized fuel tank. He made it far enough to get towed here as a no start. Fuel line at top of tank off was not snapped or locked on tank fittings.
Another good on 6.4 Doing a high pressure pump. Looked inside one lifter lobe on cam almost gone. Roller on tip of lifter gone. Turns out guy just bought it. He was telling us how he could not believe he bought this 6.4 with 200,000 miles cheaper than a 6.0. I think he knows now why that is.
