I have a 2p04 lexus rx330 it recently overheated while I was going down interstate i turned it off and coasted to gas station. Let cool and tried to start next day cranked but sounded like it was not getting spark or something took home took apart and replaced head gasket changed oil filled all fluids and got all back together and still wouldnt start sounds same as when it first overheated is there some safety thing might have been tripped or idk I just dont know someone plz help me

 

Oh boy, sounds like you are in deep with this repair already.
What caused the overheat?
How hot did it get?
Did you diagnose the head gasket leak or just pulled the engine down looking for damage?
Compression test done?
Leak down test?
Got fuel at the rail?
Does it sound like it's trying to start?
Any codes?
Any more details that you think would help us figure out what's going on can help cuz it's impossible to guess without more info.

 

Just one?
Are you sure you have a Lexus RX 330?

Head gaskets on this V6 would be a major repair.
