Need firing order for 1994 bravada

The main thing is to read that check engine light code. That will give you the answer, but maybe incorrect firing order is causing it?

So check on the firing order FIRST. When changing the distributor cap, you should do one wire at a time off the old one. Same for replacing spark plugs, do one at a time. Having one lead in the wrong place is a sure fire way to get real real rough running.

Hey 94 TOY...

When did the problem start? Before you changed the wires and plugs? Or did it start, AFTER you changed the wires and plugs? Did the problem remain the same BEFORE & AFTER you made the changes?

1 - If the TOY ran fair to Okay before you did the work, then you may have done something wrong when you made the cahages. Check for correct plugs and firing order. Check for cross wiring. With engine runing pull one plug wire off each plug one at a time. Each pulled plug wire will slow down the engine. When you pull a plug wire that doesn't react and does not make any change ON or OFF that cylinder Plug.
Then that cylinder is not firing.

2 - Check for spark at that wire. If you do-not have Spark there, But the other wires do... the wire going to that cylinder is BAD.

3 - If you have the correct firing order and spark at all cylinders then the cylinder that did-not change the speed of engine has a compresstion problem. Bad valves, Piston or rings are bad... Major engine work and Major repair bill for the repair job.... GOOD LUCK....

sounds like you crossed a couple of plug wires ...re check fireing order .

If your trying to change spark plugs remove one wire from a plug, replace that plug, reinstall the wire onto that plug and move on to the next plug. You don;t need to worry about firing order unless you plan on changing the wires or the cap and rotor. Even if you where to change the wires if you did them one at a time than the new ones would be in the exact same place as the old ones and there is nothing to worry about,

Check for bad spark plug wires or wires connected to the wrong cylinder.

on the backside of the engine close to the top there is a bleeder valve in the fuel line.check your fuel pressure there.if gas comes out and sprays basically to the top of an open hood,your pressure is fine.check the spark on your number one plug.it has to be a bright blue spark.if not change your pick up coil.make sure you also purge air out of the fuel lines.any leaks in the system or air in the lines will cause it to not fire.the bravada requires an ungodly amount of fuel pressure to keep your engine going.hope this helps
