Went 4 wheeling, crossed a river and got to the other side and fj cruiser died and won't start. Am not stuck in desert and too rough to tow back, so will have to hire a mechanic to drive an hour into the desert - sure that will cost a lot.

Yes there is a fault. Get the DTC codes read.

change the fuel filter and check the fuel pressure

this obd2 trouble code table can help u understand the meaning of code.
po522, the possible solution:
The most likely cause is a faulty oil pressure sensor/switch.
for p0688, you can Check all the ECM fuses, if the fuses are OK try replacing the ASD relay.

Don't try start the engine when the oil light turn on, it would harm your piston, camshaft and crankshaft
It should be the oil pump has broken and need to replace, tow your car to the nearest service center

Bad/leaky capacitors on the ECU board.
The salvage yard should warranty it.

Look on the back of the engine, on the same side as the plugs & distributer. There is a rubber cap on the fly wheel, and the timing marks are in there. Good luck!

generally when a landcruiser doesthat it is because the alternator is on the way out -----get checked out by an auto electrician

there is a inline fuel shrader valve {like a air nozzle} depress the valve and crank the motor see if you get fuel. [email protected] email me when the cars home i can give you a few pointers.

start by checking all the fuses inside the car and under hood

If just found this on another forum:

A few days ago I started the Cruiser and had 4 indicators stay lit.
They were the CHECK ENGINE...SLIP INDICATOR..VSC TRAC..VSC OFF.
Didnt noticed any change in driving and 4-wheel drive is still working.
I removed the negative cable from the battery and the same indicator lights have NOT come back. Everything is back to normal as far as warning lights go. Should I take it in to the service center and have it checked.
Or should I wait to take it in, if it does it again?
