This sort of thing only happens to the SPI engine.


To the OP, please identify your engine for us. Go look under the hood, Ford used 2 different 2.0 engines in that YM vehicle. One will have spark plugs that go into the top of the valve cover, and Zetec on the valve cover. The other will have spark plugs that go into the side of the cylinder head, and "Split Port Injection" on the valve cover.

Dropping a valve creates a lack of compression, as does a timing belt, so if your engine is turning over faster than it used to- that is a sign of something other than a fuel pump. You should be able to hear the fuel pump buzz for approximately 3 secs after turning the key from off to on. You can hear this in any car, so go listen in a running car so you know what to listen for. If you don't hear the fuel pump buzz, that is one sign of a bad fuel pump.
