My expedition will turn over but will not start, batery is full

check that battery has a full charge andcheck the batery conections for corrosion and tighness

See if you can jump start the car from another battery which is sound. If you can then the battery you have is rubbish and must be replaced.

my ford 2000 expedition eb will no start; batery ok starter ok selenoide ok

Easy way to check. Crank the vehicle while running remove one of the battery cables from the battery if the ingine dies your alternator is bad. I'll bet it is the alternator.

fuel pump may be going. try this. turn key on, listen for fuel pump to run for 5 seconds. Turn key off, wait 15 seconds or until you hear relay click inside car. Turn key on again for 5 seconds and ff for 15 seconds. repeat once more. This will pressurize fuel system to 40 psi so injectors have full pressure. If it starts quickly now, you are getting bleed down through the check valve in the fuel pump or the fuel pressure regulator on the fuel rail.

Hi , If you turn on the headlights on dip/full beams , then crank the engine and see if the lights dim considerably ........... If the do it's a battery voltage type problem, If they don't it's a starting motor type problem . ie open circuit or dud starter,

My 1985 astro van doesnot start, batery is ok, tank full of gasoline, all sparkplug conected, I turn the key on and the motor start like it want to start but nothing

not to shure what condition your battery is in as well as the cable connections those corrode real fast check ur battery terminals and clean them with sandpaper aswell as cable connectors and reinstall try you may need a boost when u get it running check voltage gauge notice voltage should be 13 15 volts on a battery that needed a boost to get trck going . using a 12 volt test meter while running pop hood and use tester to see batery voltage after cleaning cables if there is less than 12 volts replace alternator ok good luck hope you geter up and going
