Does the bravada have spark plug wires going to the spark plugs

Hey Arnold,
First, you need to get a precut set of wires and a set of new spark plugs. It will be proficient to change one wire and one spark plug at a time... this will prevent a mix-up and cross-up of wires.. You will know which size spark plug wrench when you get the new plugs.. They will be either 5/8" or 18mm or 13/16".
Take your time and you can do this!!!

If you want to check to see if you are getting spark - remove a spark plug and reconnect the plug wire. Be sure the plug is grounded to a good ground on the engine and try to start the eng. If there is spark seen at the electrode of the spark plug then it is not your ignition system (as far as spark goes) If you do not see spark it could be your coil or possible your ignition module (in distributor) I'm guessing you have an ignition mod - you do not mention the eng you have.

the easiest way to get at them is through the wheel wells. Jack up the side of the vehicle you want to change plugs on to gain some extra clearance in the wheel well area. Remove the inner fender liner (floppy rubber part held to the inner fender with the plastic retainers). You will then be able to see the spark plugs/wires. a spark plug socket, swivel, extension, and ratchet will make the job go by quickly.

The middle cylinder on the drivers side can be a real bear since the steering shaft runs right in front of it. They make a spark plug socket just for this cylinder or you can use a regular spark plug socket, a short wrench, and a pry bar to get it to break loose.

If your not familiar with changing plugs I would not attempt number 5 yourself (the one behind the steering shaft). You could easily break it and end up in a pickle!

Other wise do them one at a time making sure to put the plug wire back on as soon as the new plug is installed to avoid mixing them up.

Good luck.

remove front tires and access plugs after taking inner-fender splash panels off. Remove wires with a long hook tool carefully pulling at end of boots. One plug may be blocked by steering shaft. Use hex-ended spark plug socket with open-end wrench to remove that one. Have Fun!

You have no spark at a plug wire or at the coil wire?

Hey , check your ignition cord from the distributor cap to an ignition box. My blew off and caused the same problem. The connection could be corrorated if not blew off. I had to buy all the spark plug wires to get that exact wire ( only cost 20 dollars for set) but replaced and it fired right up. I also bought spark plugs and tuned it up as well. Thats also easy just remove your front tires and the plugs are right there man. Best 35 dollars I've spent in while.

If the odor is not heavy gasoline, then they appear to be oil fouled. The cheap fix is to buy at any auto parts store oil burning plugs or sleeves, these will keep the spark plugs slightly further out of the cylinder, out of the oils way, and should provide a reasonable resolution.

Check the PCV valve and hose, if they clog they will cause oil to enter engien cylinders. keep me posted

you can remove it with a swivel plug socket
