How do you change the coil pack on a 2006 pontiac grand prix?


The answer to that question is TOTALLY different depending on which engine your Gran Prix is equipped with. The choices are:

> V6-3.8L VIN 2
> V8-5.3L VIN C
> V6-3.8L SC VIN 4

This is really must know information - especially if you are asking somebody for help with your engine, engine accessories, or engine control systems.

I have a 99 pontiac grand prix the DRL's work but the headlight and brights dont work i have replaced the bulbs the fuse and the breaker switch as well as the switch nothing seems to work even checked...


With the Key in the RUN position, check for battery voltage on the brown wire in connector 2 terminal H at the DRL module. Also check for battery voltage on the pink wire terminal C of the same connector. if you see battery voltage, then the IGN switch and the two fuses supplying power to the DRL are working fine.

Next, check the brown wire in connector 1 terminal H at the DRL module for battery voltage

How do I change the fuel filter for a 2002 pontiac Gran Prix


Release the fuel pressure by loosening the gas cap, raise and support the car on jack stands,squeeze the plastic tabs on the male end of the connector,and pull the connector apart.Some models have 2 tabs,and others have 1 and the fuel line screwed into the other side.Remove filter mounting bolt,unhook tab from frame and remove filter. when you put in the new filter, make sure the arrow is pointing toward front of engine.On the line with plastic tabs, just push on till you hear a click, then pull on it to make sure it's latched.Don't forget to tighten gas cap.
