My card wont start.it's a mitsu 96 magna 4 cyclinder..there is power to and from the battery..but not turning over when turning the ignition..is it the starter motor? If so how do i replace it..do i need to lift the front end to get at it?

Check every switch,solinoid, and wires from the ignition connector to the starter, with a volt meter, follow the 12 volts from the start button to the starter to the battery.
On a wild guess, the starter solinoid doesn't have 12 volts coming out of it when it is engauged.

Best of luck!

dont know what the heck the other answers were trying to do fix
T he question was how to remove the starter motor on a 4 cyl magna 1988 mitsubishi .. that makes it a TN or first gen magna

ok TN can be either carby or an EFI setup
disconnect battery
14mm bolts two hold the starter on
undo the battery positive cable on the starter

and the ignition wire on the starter

On an EFI you have to go under the engine and undo the support bracket of the efi inlet manifold to get the starter out
underneath the car
the interim shaft is one of the bolts holding the bracket to the block
on a carby you can do it from the top
from the drivers side

have motor/engine starter unit checked, probably broken/lose gear, hence the woo noise and fails to start.

Had a big problem with misfire on my hyundai accent. Different codes, none of them pointed to specific problem. Turned out it was a bad ignition coil.

could be the crank sensor, you need to check spark and fuel delivery, if you have fuel then its got to be the high tension side of things that are wrong, does this model run off a coil pack for the ht, could be that, you said you change the alternator, check connections at the rear of alternator, this could be the supply for the ht etc,good luck.

check all your fuses sometime when giving a jump start
a surge of power a cures and blows out the main fuse

Have you tried bypassing the ignition? Turn the key to the on position and cross the starter terminals with a screwdriver. If it starts then you will need a new ignition or possibly a new ignition module.

Does the Security light come on when you try and start it? Does the actual key turn?

Try this link .Ifound it put me on right track for similar problem

ASE Mechanic here. check all the fuses to start, and check voltage on battery. if there was a battery draw all night the vehicle might have started but the alternator could not charge the battery because its power was too low and causing the ignition to die and then not allowing the vehicle to start. keep me posted!!!!!!!!!!!
