3 injector FAQ

FAQ: What are the reasons for black smoke?

ERIKC Answer: pistons, piston rings, cylinder sleeves and other faults

Cylinder liner wear, piston wear, piston ring heavy rings, etc. (Gas ring oil ring gap coincidence leads to leakage in the cylinder, cylinder pressure decreases.

FAQ: Longer Crank Times

An injector leak will cause the rail to lose pressure while the vehicle is sitting resulting in a longer than normal crank because the rail will need extra time to pressurize.

FAQ: Heat Soak​

Since the formation of these deposits is a normal consequence of engine operation, detergents are added to gasoline to help keep the injectors clean. But if a vehicle is used primarily for short-trip driving, the deposits may build up faster than the detergents can wash them away

FAQ: Not Enough Resistance

An injector becomes clogged with fuel varnish deposits and fails to deliver its normal dose of fuel when it’s energized, or

Fuel pressure to the injector drops below specifications because of a weak fuel pump, plugged fuel filter or leaky fuel pressure regulator.

This can leave the air/fuel mixture too lean, causing the cylinder to misfire.
