Does my 1999 rx300 have a oil pressure switch or a fuel cut off switch?

What is your question?

Before my car died I had to turn the key on and off really fast to get it to crank. Then I noticed the gas gauge was not working right. Then my gas tank was on E and I was trying to get to the gas station. While driving my car didn’t sputter out it just shut off and it wouldn’t start. My friend went and got some gas and brought it back. I thought I should wait at least 5-10 min before starting the car and not being a mechanic I ignored that and my friend spent 10min trying to start the car. It was totally dead. It wouldn’t even crank or turn. I replaced the starter and checked the fuses. I replaced the main fuse that was burnt. The oil level was super low and had been for awhile (i didnt know—-long different story). I put in oil then replaced the fuel pump. When I removed the fuel pump I noticed my gas tank was more than half full so I knew I hadn’t run out of gas. It cranked but didn’t start. Checked fuel pump circuit wires. Dead. Now I’m not sure

How long has your 1999 Lexus RX300 had this problem?

Few weeks
