I have a 2000 ford focus that will crank but not turn over. I replaced the battery because it did not test good. I just changed the Alternator earlier this year and the starter is about 2 and a half years old. I was told to test the fuel pump, but i'm unsure how to do this. Also do you guys think i should try changing the spark plugs?
There was an issue with the fuel pump on early Focus models. The only way to tell if it's bad is having a shop or dealership do the test to read things like pressure and perform a diagnostic.
It'd be more helpful if you tell us what engine you have, and what your mileage is right now first. A Focus that doesn't start can be caused by one or a few things happening all at once.
Okay If the engine is turning over the battery, alternator, and starter are not the problem. If someone sprays starting fluid in to the throttle body while you hold it OT while turning it over will it run? When you turn the key to the "on" position (without cranking) do you hear the whine of the fuel pump? It should probably last a few seconds, then when it reaches pressure it turns itself off. It primes the fuel rail for starting the engine. If you do not hear this, you need to check the fuse. If the fuse is fine the relay could be bad. If the relay is fine you need to check the power wire to the fuel pump for 12v. If you have 12v then the fuel pump is bad. If all these things check out you can test the fuel pressure to see if it's getting ~40psi. If thats okay, then you can check for spark. If you remove a spark plug and leave the wire connected you can ground it to any metallic unpainted part of the car, like a bolt, or a bare metal spot. Turn the car over and you should see it arking repeatedly. If there is no spark you could have a bad coil or crank sensor.

Thank you for the tips Thomas i do hear the fuel pump when i turn the car to the on position I think the next step im going for is to test the pressure and possibly change the plugs because im pretty sure their due to be changed anyway
Ok guys everything seems to be checking out....think its time to test the fuel pump I have to see if someone i know has a gauge or possibly see about gettin one from ebay or somethin....will keep ya updated
Thanks for the help guys it ended up just being a loose connection to the ignition sensor
