The car would sometimes refuse to start. Eventually the car was towed to repair shop. The problem was traced to inability of fuel, sometimes, to reach the engine from the fuel tank. The fuel tank was removed and cleaned. The mechanic also changed the fuel pump. The engine started after these procedures were done.
Immediately after I left the repair shop I noticed that the engine would stop if I go down an inclined surface. I tested inclining the car, with its nose slightly lower than its tail, and engine would stop in this position every time. No problem as long as the car is in a level position.
Suspecting that fuel gauge might be in error (on the theory that the part of the fuel tank where the intake pipe of the fuel pump is located "dries up" when the car is inclined forward) I filled up the tank with more gasoline until the gauge showed half tank. The problem was solved. Engine no longer stops even when tilted forward. But, as soon as the fuel gauge edges down a little bit (still one-fourth tank) the problems recurs.
What could the problem be?
1. Erroneous fuel gauge?
2. The position of the intake pipe of the fuel pump in a wrong position?
I noticed during the repair procedures in the repair shop that the mechanic punched a hole on a wall that immediately surrounds the fuel pump in the fuel tank. I don't know why he did that and I failed to ask. Could that be the cause of the problem why the engine would stop when the car is inclined forward?
I am a missionary in Cambodia where Toyota Camry is the most used car. I bought mine from another missionary who have used it for more than a decade. I do my best to keep it running at the least possible expense. The problem is, it is hard to communicate to local mechanics that can only speak Khmer.
I would be very grateful for your help. Thank you very much.
