Symptoms Of A Bad ‘Spider’ Fuel Injector Assembly

The most common type of failure (related to the ‘Spider’ fuel injector)
is usually not the assembly itself going bad, but the fuel pressure
regulator going bad.

The fuel pressure regulator is
infamous for leaking fuel from its vacuum inlet nipple. When this
happens, the engine can suffer backfire explosions (in the plenum due to
the leaking fuel) that catch the nylon plastic fuel injector lines on
fire. The end result is more fuel leaking into the intake manifold and
causing some of the following symptoms:

• Rough idle

• Black smoke coming out of the tail pipe (when the engine is running).

• Really bad gas mileage.

• Check
  engine light is on with misfire codes (usually a P0300: Random Misfire)
  and Air/Fuel Mixture too Rich Codes (P0172, P0175).

• Hard start, extended cranking time and possible No Start Condition.
