Does your 1.7 make a knocking sound just at starting? It happens just before the engine starts to run. Mine has always done this & I can't find anything loose or anything hitting anything within the engine bay. Normal? Thanks.

Does start-up always use the same firing order?
All is tight. New belt & snug pulleys. 48K miles. This has nothing to do with the fuel pump IMHO. Happy Thanksgiving. |
