SOURCE: oil leak problem with 1996 toyota camry

I am going to see a mechanic - my trusted mechanic who does not nickel and dime me - to see what this is. I have the same problem and he told me he has never done this job on a Camry and is unsure. Given the miles, he has suggested that maybe it is time to part ways with the car. I am going to ask him if he will put some florescent dye in it and let me drive it for 50-100 mi and then check to see where the leak is and fix it. Let you know what happens. I have to try, the car is solid.

SOURCE: 95 toyota camry died and turns over but wont crank

same thing happened to my sons' Aries. we replaced timing belt and everything worked great> to confirm broken timing belt, remove valve cover >crank engine over and watch valve train, no movement= broken belt. you can check tech manual but as previously stated if this is not an interferance engine, cranking engine won't run a piston into an open valve. good luck.

SOURCE: 2003 toyota camry won't start. Had battery tested,

Could be the starter motor, bad battery connection, starter motor solenoid, faulty ignition switch, siezed up engine.
Turn the head lights on and try to crank the engine, if you hear a click and the lights dim, it is a bad battery or a loose battery lead. If you hear a click and lights don't dim, bad starter. If you don't hear a click, it is the starter solenoid. If nothing at all, bad ignition switch.

Check the ground cable going from the battery to
alternator, then to chassis. Make sure there is no
rust at the chassis ground wire terminal, and that it
is very tight. The fusible link will be off the alternator
red power cable,usually, but not 100% on that car.
Good luck.

The pump gets power from the circuit opening relay and the EFI main relay, which are supplied through the EFI fuse. p219 here
