2005 Ford F-150 4.2L suddenly gave me troubles yesterday. Happened not while driving but when I tried to start it up, it did start but the engine was shaking and it immediately died. Today it didn’t start and later it did start for a second but again died immediately. So It does turn over, it’s not the battery or the starter. It seems to be either a fuel system issue or a timing issue. I plugged in a diagnostic tool and it gave me no codes. I tried replacing the fuel filter which didn’t solve the problem. I’m thinking it’s probably the timing chain but if anyone has any thoughts I would appreciate the help. ---

The crankshaft position sensor may have failed. [https://www.1aauto.com/content/articles/bad-or-failing-crankshaft-position-sensor-symptoms](https://www.1aauto.com/content/articles/bad-or-failing-crankshaft-position-sensor-symptoms) Tester ---

The fuel pump failed. Pound on the bottom of the fuel tank with a mallet while someone cranks the engine. ---

My vote is for the fuel pump. At 16 years of age it’s had a good life unless it was replaced already.
