need help can't get my 1990 240sx to start

[TheNiceGuy333]

so i recently bought a 1990 240sx and when i bought it the guy said he thought the neutral safety switch was going out cause you would have to push the clutch in a couple times in order to get it to turn over and start. well once i got it home it sat for a couple of days and when i went to start it, it was being difficult and was doing what the guy said it was doing to him. And i got it to start then turned it off and tried later that week and then it wouldn't start at all and for a day or 2 the power was completely gone when i turned the key and then it stopped doing that. so i replaced the neutral safety switch and it still wouldn't start, then the battery still nothing, then the alternator, and the starter and still no start, so as of right now it clicks when i turn the key but it won't start. And i can by pass and get the car to turn over at the starter and then have someone inside the car turn the key to get it to start. And i haven't messed with the starter relay. and if i remember correctly the ground is fine and isn't to corroded. Please help its probably something simple and stupid. Thanks for your time!

and when i turn the key it sounds like it clicks in the front left of the car and the front right!!!

Doubl chck all grounds and clean your battery cable terminals. Even a little corrosion can cause similar issues. Also check your start signal connection at your starter. If that dont work try a new/ known working ignition switch.
