Most of these have coil near plug setups, if this is true for you then you want to check the Crank sensor next. If you have a distributor then you might need to change the cap and rotor.
The original fuel injectors on that model were recalled - did you ever have them replaced?
There are eight injectors, and possibly a ninth one, if it has a cold start injection system. there should be 1 per cylinder
At least the slave cylinder. The clutch master cylinder can be replaced at any time.
It did when new. It should still unless a key cylinder has been replaced.It did when new. It should still unless a key cylinder has been replaced.
It should be replaced when it begins making a noticeable noise.
If it's running like it's supposed to, there's no need to replace it. I have an 87 Silverado, and it's never had the injectors replaced.
A master cylinder should be replaced when it can no longer provide the pressure needed for the brakes to operate. You can tell it is failing when the pedal becomes soft.
No, the chain should last the life of the engine.
unscrew the injector lines from the top of the diesel injectors, and from the injection pump. The diesel injectors can be removed with a 27mm deep socket ratchet head, or a 27mm wrench. Be very, VERY careful to keep the threads clean or you can crack the head when putting new injectors in. If your injectors are bad, they've also probably damaged your glow plugs. You should probably replace them too (they're just under the injectors on the front of the cylinder head).
The 2009 Honda Accord 4 cylinder does not have a belt. It has a chain that should last the life of the engine.
I usually reccommend about every 90,000 miles.
It has a timing chain which will last the life of the engine.
