not a fan of the quicky lube syphon method.. its fast and easy and saves time for Quick Oil Change shops but I seriously doubt it removes all the sludge in the bottom of the pan completely. or the metallic debris on mag plugs . The drain is the lowest point and everything will come out if engine is hot and you can clean the plug for fresh use. . Trans shops now use similar methods of quickie replacing fluid by machine with fresh fluid.. But you still have your old dirty filter inside trans and whatever sludge and debris are in the bottom of the pan. .
Well, it wasn’t either of those, after tracing wires, cleaning every connector and adding dielectric grease, no bad wires and fuse was the first thing I checked/changed. It was the relay, $45 on eBay and it’s now running again, with a much quieter fuel pump to boot!
