1997 avalon wont start fuel pump when key is turned to "on" position and hencar wont start. Also, the car wont start when the fuel pump is hard wired to stay on. Any ideas
There are still many possibilities. The internal combustion engine is a complex mechanism. The timing could be off. All spark plugs must be firing. They must fire at exactly top dead center. The timing chain/belt must be in good working order, not worn or stretched. The cam shaft must not be worn out so the valves open and close correctly. the valve lifters must be working properly. the cylinder heads must have the same correct compression. A different compression indicates bad valves or head gasket. Piston rings must not be worn out or they will not provide adequate compression. the oil pump must circulate the oil to lubricate everything, and provide fluid for hydraulic lifters. Oil and filters must be clean and the correct type for engine and climate.

1998 toyota avalon spark plug problems
A common problem on these engines are the ignition coil packs, there is one for each cylinder, do you have any diagnostic code information so I can help diagnose the problem? The cat converter overheated due to the misfire.
