It seems no one knows the answer. It may be a circuit breaker instead of a fuse. Or maybe a fuseable link. I found several YouTube videos on replacing the motor, or replacing a plastic gear that's part of the system. If you watch them, it may point you to an answer.

Have your catillac converter checked out

Most car alarm and stereo installers may be able to help you. I took apart the driver's door lock on one vehicle, removed the tumblers and reassembled it but eventually someone messed with it and I was stuck

Yes if it has a program key

If u have repaired coolant problem and light well not reset. Problem is not fixxed then. Look for something minor like cap on not holding correct pressure overflow tank has a sensor inside that may be bad.

Best bet is the it to a toyota dealershipnor Napa and have them hook up the computer. They will tell you if your timing is off.

Please check plugs, plugs wires and distributor connection

check for spark from the spark plug wire pull the plug wire put a screw driver in the wire hold it by the plastic handel so the shaft of the screw driver is close but not touching a ground and watch for a spark be careful not to get shocked or see if the fuel pump is bad sometimes you can hit the gas tank with your hand while you turn the engine over you have to hit hard and fast while trying to start it this means the fuel pump is bad if it starts because it will stop again

Water or contaminants in the fuel system or possibly a bad plug wire? It can also have developed a vacuum leak at the intake manifold or an emissions system failure is possible first check your sparkplug wires that's the cheapest route! I feel like it might just be a plug wire is broken and is jumping spark or the timing belt may be stretched? Look at your mileage if around 100,000 miles then plugs and wires may be at fault?

Your fuel pump or fuel pressure regulator are not supplying constant fuel pressure. Too much or too little is causing it to kill. You can pull the vacuum line from the regulaor and check for gas. If there is none, you need a pump, it is weak.
