What is the firing order for a Ford F-150 4.9L straight 6?

Firing OrderIt is 1-5-3-6-2-4.

( also , the distributor rotor turns CLOCKWISE , the distributor cap is installed with the marked # 1 position facing AWAY from the engine , and the engine cylinders / spark plugs are numbered 1 through 6 , from front to rear )

See this page,http://autorepair.about.com/library/firing_orders/bl-fo-8571.htm

I set my 1992 EFI 4.l just like this and it runs like a top. Note my engine code in the VIN is a 'Y'.

------------------------------------------------------

To avoid confusion, replace spark plug wires one at a time.

Ford Engines;

144,170,200,240,300 (6-Cylinder) Inline

Firing Orders: 1-5-3-6-2-4

Distributor Rotation: Clockwise

The above is correct. I have been doing mechanical work, and my own tinkering for 50 yrs, and have never seen an inline 6 that did not fire 153624.

Where do the plug wires go on the distributor cap for correct firing order for a 351 Windsor engine. And what is the correct setting?

If you are standing in front of your vehicle looking at the motor the #1 plug is on the left side closest to you (left front). #2 is the 2nd one back on the left side, 3 and 4 being the last one all the way in the back on the left side. The #5 is right front 6, 7, and #8 is the right rear. Distributor rotation is counter clockwise.

What is the firing order for a 1999 Chevy S-10 2.2L 4 cylinder?

i believe it is the same as my 98 s10 2.2 l and the firing order is 1-4-2-3 (where cylinder #1 is the closest to the fire wall) and your distributer has the plug wires running almost vertically 1st cylinder = the very bottom and 4th cylinder = second from the bottom and 2nd cylinder = second from the top and 3rd cylinder = the top connection on the distributer.

What is the firing order for a 1990 Ford 302?

clockwise 15426378

The rotor turns counterclockwise and the order depends on if you have an engine with a roller cam or a flat tappet cam. If it is a flat tappet cam, it is 1-5-4-2-6-3-7-8. If you have a roller cam, it is 1-3-7-2-6-5-4-8. You will either have an H.O. motor or not. H.O. is roller motor.

How do you install a efi ford 302 in a car that is not efi?

You'll need to cut the wiring harness out of a donor car that has a matching efi system and transplant it into yours. You'll also need the eec computer from the passenger side dash of the donor car. I would recommend using an early nineties system as they have the mass air sensor on the intake instead of the less useful speed density unit. All though you would have to remove that from the intake of a 90's 302 and transplant it if you're intake is meant for speed density. Worth the upgrade if you plan to do any mods for hp

After changing the spark plugs wires and cap in a 91 Cadillac DeVille what would make it sound like it is still 'missing'?

I suggest accessing your 1991 Cadillac Devilles onboard computer and obtaining the fault CODES that are stored in the computer.To do this:

1. Turn ignition switch to the ON position. Do NOT start the engine.

2. Simultaneously push and hold the OFF and WARMER buttons on your Electronic Climate Control panel for 3 seconds and then release them and while watching, you'll see your fuel data display change.

3. On your fuel data display, you will see LETTERS & NUMBERS displayed. Be prepared to write them down. As they run through fairly quickly, I suggest making a column list ahead of time on a piece of paper. Heading each of the four columns in order with these codes, EE And E And FF And F . Then as these codes flash, write down the number displayed under each of these coresponding codes number

Then when it stop's at .7.0 the code's are done.4. Turn ignition switch OFF.Now once you have the error codes, the answer to your question maybe at your finger tips.Good Luck

NewCheck that none of the wires are touching the exhaust manifold, you can use tie straps to tie the cables so that they are not touching or near an extremely hot surface. You can burn up a wire and cause SERIOUS engine damage, if its been goin on for 2 weeks or so get your front motor mounts checked out, theres a possibility it may have cracked.

Did you change the rotor button as well? This problem your describing really needs to be described in much more detail as to how and when this miss started the more information you can provide is the easiest way for others to understand your situation. , EzForJesus

Is it possible that you inadvertantly tossed out the grounding strap when you replaced the cap? That might be your problem...I would just hit a junk yard and grab another one. It's a cheap way (about $5) to see if that troubleshooting works. If not...the mid to late 80's and newer are known for electrical frustrations with that computerized stuff. Good luck!

You might want to check the timing. I'm not sure how to adjust it but you definitely need to see where it's at. Also how many miles are on it? If it is a lot the timing chain may have stretched and may need replacing.

Make sure that the wires are properly routed to the right cylinders. Also make sure that the wire snaps into place when connecting them both to the spark plugs and the distributor cap. If a wire is not properly seated to the plug or to the distributor cap the cylinder that the wire goes to can fail to fire properly. Believe it or not the voltage that needs to go across the tip of the spark plug is aroung 16k volts, not a whole lot of amperage but it insists it get plenty of volts. Improperly connected wires can realy play havoc with the way the engine runs.

Why does a car backfire?

A car backfires because unburned fuel is getting to the muffler. The heat of the exhause system causes the fuel to combust, thus a backfire.

I have just been told that the rubber on my exhaust has split - could this be why the car would backfire?

I have heard something about air getting into the exhaust could cause a backfire?

back fire can be caused by different faults. first is to much fuel because of worn carburetter, or wrong adjusments on carburetter. choke sticking will cause backfire. timing be out of adjustment will cause backfire exhaust leak can cause backfire. bad spark plugs, or plug leads , distributer cap worn of cracked will cause backfire as for fuel in muffler, if it combusted in muffler , the muffler would split open it is not that. and i dont know of any rubber on an exhaust that would take the heat aexhaust manifold gaskets could be problem but if they were rubber they would melt \

is it good or bad to have backfire

It can also be done with intentional modification, such as done in ''Keeping Up Appearances'' British sitcom. A fuel line and an oxidizer line are added to the muffler with a manual rubber bulb pump added to the line as the ''backfire button.'' At a point before entering the muffler, the lines have a pair of backflow valves to prevent the flame from racing into the mixture tanks. Squeezing the bulbs dispense a mixture of pure alcohol and an oxidizer into the muffler to create a reaction. For Onslow's car in the TV programme, copier toner was squirted in the tailpipe for a heavy soot effect on the backfire command.

Having a car backfire can shake off any parts that aren't bolted completely, and can cause the engine to stall because the pressure of the backfire can temporarily disrupt the exhaust release from the engine.

Besides, it would spook horses, cows, or anyone not used to loud noises. So having the car backfire down a Harlem road won't have the same effect, as a car backfiring down a rural city road.

What is the spark plug wire sequence for a ford V8?

Which V8, Ford has made many over the years. Ford has/had two different firing orders for V8's over the years: 1,3,7,2,6,5,4,8 and 1,5,4,2,6,3,7,8 If it is an older van, the second one is more likely, because the first one was usually found in high output applications like the Mustang GT. If it is a newer one like a 4.6 or 5.4 liter, the first one is more likely. Try one then the other, and see which one makes it run. Rdemember also the numbering of the cylinders on a Ford is not like a GM. The cylinders on a Ford are 1-4 up the passenger's side and 5-8 up the driver's side.

If a 1985 VK Commodore has a red 202 but will not start after installing a new distributor could it be the firing order and if so what is the firing order?

I also have a VK with the same problem. After many hours spent checking and replacing parts including the distributor I have come to the conclusion that it may well be the black box computer. This is found inside the firewall on the passenger side of the car. Not sure on how much it is to replace but I may well cut my losses as I have spent a lot of money already.

i'am no expert or anything like that but since i got a vk about a year ago i have leant a lot about the engine. i think that you are right, my vk has a black motor and i'am not sure if the operation is exactly the same but in the black motor that little box/computer reads the signals from the crank angle sensor (a small little thing bolted at the back of the engine and goes into the top of the bell housing) if you try to remove the crank angle sensor from the engine it will not even start because the distributor in the black motor is not operated the same way as normal distributors (it has no vacum lines attacted to it like normal) it is very simple in design and i think that the box/computer controls the operation of the distributor

A VK Commondore? What the heck is that?

assumeing its a 4cyl the fireing order is 1-3-4-2 going when you take off the dizzy cap there should be a notch on the outer edge this would indicate cyl1 rotate the engine to see which way the arm rotates the from that notch point afix the HT leads in the order of 1-3-4-2 and that should do it if it a v6 it will be 1-5-3-4-2-6 and for v8 1-5-3-4-2-8-6
