have a 1993 Lexus gs300.. will crank but not start. Replaced all blown fuses, new battery and alternator... still won't fire up.. the car has been sitting for over a month, it just seems like it's not getting fuel... could it be the fuel pump relay? If so, where is this located? How much to replace? Since I've replaced parts, the radio, locks, interior lights all of a sudden Stopped working... wtf is going on with this car? It's one thing after another, and I can't afford to get a new vehicle right now.. please help 😢

You need only a few things for starting an engine, fuel, air and spark.

Which do not you have? What is the fuel pressure? Is the spark strong?, I assume that it gets air ok.

With the interior lights, locks, and radio are not working I would assume that since all fuses have been checked that it must be a relay or sensor? I don't have a user manual so I do not know where any of these would even be located on my car. I would like to find out how to check the relays. Does anyone happen to have any knowledge or experience with this.. thank you

It could be an immobilizer issue. Does your security light turn off when you insert your key in the ignition? To reset it turn the key to the "on" position but don't crank it. Leave it for 5 minutes or so then take out the key and try to crank it again.

Also try locking and unlocking the driver side door a few times. Using your key and not the FOB buttons.
