In the 2002 it is under the rear seat on the driver's side maybe the same for yours
In the gas tank.
If the Bravada is not starting but the engine turns over, check for spark at the plugs. If there is no spark the ignition system will need troubleshooting to find the problem.
No it isn't.
Possible vacuum leak either under hood or under dash Check valve on brake booster?
Look in the fusebox.
under the hood in the smaller fusebox
the fuel filter is probably clogged and resisting flow otherwise the pump is burnt out
If you are looking for the fusebox in general its located by the battery. Just take your seat off and look by the battery. That's where its located on my 93katana750. Good Luck
Check the fuse. Look in your owners manual for the location of the fusebox & a diagram of the fuses. Conversely, if you already know the location of the fusebox, there is usually a diagram in or near it.
The fuse box is under the hood if your facing the car from the hood look to the left,
to the left of the steering wheel all the way behind the clutch pedel and up
In a 1993, my car, the fusebox is located to the left of the steering wheel, about knee high. Snap off cover to check fuse. Be sure to reattach cover as fusebox poses a risk of injury if let unprotected.
