Car wont start after replacing battery

you would have to check for proper fuel pressure and spark , something else may have quit by pure coincidence

I hear fuel pump come on

what about spark ? are the injectors firing ? you hear the pump but you should still check for pressure , after spark and the injectors I guess

What about ignition control module?

these things have to be tested , if you want to go ahead and spend money on speculation go right ahead

I know but it cant be nothing major all i did was change the battery and it started once after that
