HOW DO I FIX/REPLACE STARTER ON 1999 MALIBU?

probably where the remote start wire was taped into the starter wire got broken and now the key side isn't attached to starter anymore. Id check the starter relay and fuse before anything

sounds like a bad solenoid on the starter. replace the 1999 starter(Its old).

Intake gasket is shot or of it has been replaced it was poor work
These engines are famous for intake gasket issues more so if it has GM dexcool antifreeze. 700-1000 in shop. Find a good back yarder. Parts arround 100. Couple hun for labour

look at the oil filter then look towards the battery. it should be right there.

Remove the power wires to the starter, turn the key to start to check for power, should have 13.6 volts, or what the capacity of you batteery is at the time, check it with a volt meter. If got power, replace starter or unbolt it from engine, it may be stuck in the flywheel,you'll see it release if just stuck,then replace on car and try to start before buying a starter.

Follow the positive battery cable down to the starter.

define trying to catch. is the engune turning over but sounding like it may start then finally does? or does the starter spin but the engine is not turning unless you turn the key to start a few times if it is the latter it could very well be the starter. check to see if you have an oil leak onto the starter. if it very greasey then you will need to adress the oil leak too. the starter is located on the lower right side of the engine. (passanger side.)

Check with a battery tester if you have power at the starter, Are the Battery post clean, Are any fuses blown in the fuse Box, check for any corrision.

disconnect negative battery terminal, raise vehicle,remove splash sheild, if equipped. take wires off of solenoid on starter, remove starter mounting bolts, remember not to mix up wires!! --to install--put starter back in vehicle put in bolts,hook up wires, then replace cable back on battery.

Does the starter make any noise or click when you turn the key to start? If it does not, chk. battery could be bad, and battery cables could be loose or corroded. If there good and clean and battery is good try tapping starter see if it will turn and start if it does or still clicks starter bad. It could be ignition switch if it does nothing at all, but if it clicks most likely its starter.
