What are common problems with 2000 Mitsubishi Gallant LS dealing with fuel injection and fuel lines and valves?

Answer 1

first it depends on say engine size. 1.8l ,2.4l, or 3.0 v6. generally gallants fuel injection system are pretty sound. Not to say they can't give trouble.With that said here goes:

1. runs ruff,dirty injectors

2. won't crank,possibley fuel filter plugged

3. won't crank,possibly bad fuel pump

4. wont run,poors fuel out of tail pipe, fuel pressure regulator bad

5. valves:melted,too much carbon build up ,not running right gas for right engine,(ex. 2.4l has to run on prem. gas because it has a compression ratio of 9.5 to 1,so if you run it on reg. severe carbon build up and can cause major engine headaches.)

6. interference engines can jump time with worn belt allowing pistons to come in contact with valves damaging both severely.

7. fuel lines: i guess can leak ,if engine is hot could cause vehicle fire.

8. most problems with rough idle, stumbling,etc... caused by just waiting too long for a tune up. 80 % of engine problems can be solved by just doing a tune up.

This is know way all the problems but maybe will give you at least an idea.

The most critical thing these days is CHANGE THE TIMING BELT "before"

something happens!if looking at purchasing a used mis.galant get documentation from previos owner when belt was changed.
