I need the firing order for the spark plugs and plug wires I recently changed them and something is not in the correct order

7-2-6-5-4-8
i hope this helps as this should be the correct firing order for your car

You have a plug wire crossed check the firing order, you can look on the net for your make, model and engine size to locate the correct order. I hope this helps. Take Care.

Check you spark plug gap and make sure you have the firing order for your plug wires correct. you might also want to check your Fuel filter. theygo on in a certain direction, so look for an arrow on it. It should be pointing towards the engine if installed correctly.

FIRING ORDERS

Print
See Figures 1 and 2
To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes to reflect how your engine is wired.

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....

Make sure you gapped the plugs and make sure you have the firing order correct. If all the wires were removed at the same time, having them out of order is highly possible. Last, make sure the coil wire as well as electrical connections are in place around the coil. it's something you forgot or missed. check

Depending on your Grand Marquis's mileage...it sounds like plug wires and plugs...(worn out) and or engine timing/firing order? If plug wires recently changed...the spark plug wires are in the wrong firing order...confirm the firing order from your local parts store by phone...and retrace each one...always start with #1 cylinder...hope this helps.

FIRING ORDERS

Before carrying out extensive tests to isolate poor running problems, check connections of spark plug wires. This is especially important if plugs, wires, distributor, etc., have been disturbed recently for service. Obviously, this is not applicable to the wireless 4.7L engine.

NOTE To avoid problems, remove and tag the spark plug wires one at a time to ease reinstallation.
For vehicles with an extensive service history, keep in mind that the distributor could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason, it is very important that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired.

CHANGE SPARK PLUGS.YOU NEED SPARK PLUG 3/8 SOCKET.YOU NEED SHORT AND LONG 3/8 EXTENSIONS.YOU NEED SPARK PLUG BOOT PULLER AND A SPARK PLUG GAUGE SET THE SPARK PLUG GAP.NOW CHANGE 1 SPARK PLUG AT A TIME SO YOU MIX THEM UP GET FIRING ORDER MIX UP CAR BACK FIRE WONT CRANK.ALSO CHANGE PLUG WIRES ALSO.

Remove boot to spark plug using a boot puller. Unscrew spark plugs using a spark plug socket, extension, and ratchet.
Do them one at a time to avoid confusion. Installation is the reverse of the removal.
