first i started having problems overheating. - i replaced the radiator because it had a huge crack in it (assuming something else caused it...), replaced thermostat and the water bypass valve ("2nd thermostat"). since replacing all of that it's having trouble starting. it acts as if it has no gas, it takes a good minute sometimes of me continuously trying to start it before it will start. sometimes it won't even turn over as if the engine was seized.

we're starting to assume that it might be the water pump. haven't taken the access panel off to check the weeping hole but that doesn't explain it not starting.

when i try to burp the system continuous bubbles come out of the rad and sometimes with white smoke so we were thinking the water pump is drawing air in and causing to much pressure?

when i start the car sometimes white smoke comes from the tail pipe and sometimes even when i drive it. it's hard to tell what it smells like and i know that, that is the first sign of a busted head gasket but there is no oil in the radiator and no coolant in the engine. this car has me completely stumped and mainly because there are so many symptoms i can't narrow it down to one thing. once started the car runs fine, no loss of power.

maybe water got in my plugs (because sometimes the coolant geysers and gets everywhere with the cap off..), but i drive alot and it's been about a week it should have burned out by now. i put an octane booster and seafoam in the tank in case there was water issues and it doesn't seem to hurt or help.

also i'm having minimal coolant leakage and no sign of it leaking anywhere :/ but the a/c pours and not sure exactly where it's coming from but it drops from under the passenger seat. which i think is weird.
