Default My 1998 Ls400 won’t start just clicks once.

My car was running completely fine and then one day I tried to start it and it made one click and turned back to lock position and then tried again and it started up. But then about a week later i drove to the store and when I came back out and tried to start it and it did the same thing only one click and wouldn’t start so I had to call triple A to see if it was the battery most common usually and he said battery was fine and tried to jump so I thought it was the starter and replaced it and eveything else you should and put it back together and same thing she wouldn’t start one click can any body tell me why it won’t start maybe

first, ensure the battery terminals are tight.
next, make sure your car is in park. the neutral safety switch in the shifter tends to get gunked up and work intermittently. try moving the shifter the left and right to loosen any debris, and to trigger the switch.
long term solution is to open the area under the wood trim and clean.

what starter did you use? OEM reman? aftermarket?

So your car makes one click. It simply means that the neutral safety switch is working OK. When it is failed, the starter relay is not driven and there is no click sound at all. Why don't you bypass the starter relay in the main fuse box. You can check that the starter is OK or not very quickly if the power source is good. The actual method to bypass the relay is to connect the pin #3 and #5 of it.
