Ford Focus Starting Problem
I know there are some car tech heads on here so thought I'd give this a shot...
Just bought a 2000 1.8 zetec Ford Focus and yesterday I had a problem starting it. The engine cranked over but would not fire (or tried to a tiny bit). We checked the battery voltage and it turned out to be real low (12.2v) so I bought a new battery. It was real cold out which may have had something to do with it.
Stuck the new one in this morning but did the same thing. Battery voltage was better at 12.53 but it wasn't really firing. I then tried to start with my foot fully pressed on the accelerator and after a few seconds of intermittent firing it started ok and then ran fine. It has now restarted ok since. Voltage when running was 14.7 with lights/heater/heated screen on (so as far as I can tell the battery is being charged fine).
After I google searched I found the following suggestions:
Spark plugs dirty
Fuel injection problem causing engine flooding?
Coolant temp sensor
I have a feeling it is something to do with fuel, but not sure. It seems to run fine when its running other than occasional slight (up to 2000rpm) revving coming up to junctions when the clutch is depressed (perhaps completely unrelated?).
Any help would be appreciated.
