since fuel pump pushrods are mentioned a few times in this thread.......
If you remove the fuel pump and turn the engine over by hand SHOULD you be able to feel movement of the pushrod? I'm trouble shooting a fuel issue and tried this last night with no luck. |
YES. One should be able to see the pushrod top move up and down as the engine is turned manually; that's one way to measure how high it is at its highest point. If your pushrod isn't moving when the engine is rotated (rotate a full rotation or so to be sure), then pushrod likely bent, or gear on the crankshaft is kaput. So I think you'll need to get that pushrod out for visual inspection.
On his VW, using a very strong magnet, I was able to lift the pushrod about half an inch before it was stuck. His pushrod only protruded like 1mm past the plastic stand no matter how the engine was rotated. Using a very strong magnet, I was able to lift the pushrod about half an inch before it was stuck. So I lifted the plastic stand and the bent pushrod came out with it; the magnet made sure that the pushrod did NOT fall into the engine.
Maybe this should all be in a separate thread....

Great job giving a helping hand! That's the kind of folks you will find here. 
It goes to show that troubleshooting and isolating where the problems are helps to find the cause and identify the proper fix. It also says that keeping spares is now a requirement because the FLAPS no longer stock the typical items they used to. Having a pile of used parts in good condition can save days waiting for mail ordered or back ordered parts.
