Hi all, any idea why my F150 w/ inline 6 won’t turn over with starting fluid? It ran before, although it misfired a little, now it only cranks. I have the fuel tank disconnected because I plan on replacing the fuel pump and old gas. Thanks

    Spark or timing. Pull a plug, inspect it and then connect it and ground it out to check for spark.

      I actually changed out the plugs already. They didn’t look too bad, but they had soot and oil on the threads. Does that mean anything?

        At that point I’d check one grounded out against the block and check for spark. the sooty look is due to a very over-rich environment.
