You have to remove the fuel rails on each side and lift them off the injectors and there is two screws on each side of the rail and there are in between the injectors and when you get the new plugs ask for the double platuim-auto lites and make sure you get a small rubber gas line about 18inches long so you can get the new ones back in and do not over tighten the plug and for the flashing light it maybe one of your coil pack that sit on top of the spark plug itself if you have an autozone near you they will put it on the tested for free and you maybe able to see if they have you truck listed to get step by step how to do the tuneup it www.autozone.com i hope i have been some help to you i have a 2000 Edpedition and there are nice trucks

2004 Ford expedition check engine soon light is flashing and car shakes hard when stepping on the accelerator


Your car is misfiring. You should not drive the vehicle while it is misfiring. If you want to DIY it you can start with you ignition system. Make sure all spark plugs, plug wires, and ignition coils are secure and in good condition.

Gmc jimmy 2000 will crank but will not start what could be the promblem


does the word security stays flashing after you crank the engine? if it does vehicle has a problem with the passlock 2 system which is a factory installed anti-theft system. when faulty which is too common on those year GM models, vehicle will start and run for 2 or 3 seconds and die out. follow this procedure: 1) locate yellow 20ga. wire running out of steering column which will run along with heavier gauge wires. correct wire will be thin compared to the main ignition wires. 2) cut wire and connect an in line toggle switch and leave in on position. 3) put key in ignition and move forward and leave it that way for approximate 15 min. or until security light goes out. 4) as soon as light goes out vehicle should start. if it does not crank engine again until it starts. 5). when engine starts flip toggle switch to the off position then security light will come on. done. passlock system is bypassed. security light will stay on constant but vehicle will no longer leave you stranded.

The check engine light is flashing


Why Is My Check Engine Light Flashing? Location
  1. The check-engine light may be a graphic of an engine or similar icon, or it may contain the words "check engine" or "service engine." In some vehicles, a red check-engine light means the car needs absolute immediate attention while a yellow check-engine light means you need to make an appointment soon. Either way, you should know the location of the light and periodically glance at it to ensure its status. The light is used to indicate power train problems that are associated with your vehicle's emissions system. (The power train is the engine, transmission and other power parts of your vehicle.)
Flashing Light
  1. Typically, a flashing light is more serious than a solid check-engine light. The flashing light is meant to alert you that you may have a misfire in your engine that will cause catalytic converter damage if you leave the problem unresolved. Replacing a catalytic converter can be costly, so have the engine checked as soon as possible by a certified mechanic.
Cause
  1. A flashing check-engine light generally indicates that there is a failure in the emission control system. The emission control system contains an array of sensors that work to reduce the amount of pollution released into the air. An oxygen sensor reads the air and fuel mixture and lights up when it is out of range. The acceptable range is between 50 mill volts and 800 mV. If the check-engine light is flashing, you should visit your mechanic or dealer as soon as possible.
Loose Gas Cap
  1. A gas cap that isn't twisted on tight enough may cause the check engine light to illuminate, but it won't flash. Try tightening the gas cap and watch the light. In many cases, it will turn off because the problem has been corrected. If the light stays on for more than a day or two, have your mechanic run an on-board diagnostic (OBD) to see if there is a code in the system indicating a serious problem. Your mechanic can reset the light to off if the problem was a loose gas cap.
Spark Plug Wires
  1. As spark plug wires age, they can become brittle and crack, causing an electrical misfire. Your check engine light might turn on and stay lit. If this happens, go home as soon as possible, turn off your engine, and inspect the wires. If the wires are brittle and cracked, you need to replace them. If your check engine light stays on after the wires are replaced, have your mechanic run an OBD.

Exhaust sputters engine light flashes car shakes


which engine light? The Check engine light (yellow) or the Red engine light?

Flashing yellow means you are dumping raw fuel into your catalytic converter and will ruin the $800 cat very quick. It means you have cylinders not firing. Go to Autozone and get the fault codes to see what the cause is.

ENGINE MISFIRE TO THE POINT, THE CHECK ENGINE LIGHT COMES ON. AN IT WILL START TO FLASH. AN WONT GO OUT UNTIL YOU TURN OFF THE CAR .60-65 IT WILL STOP, AS SOON AS THE CAR START TO SLOW DOWN.IT START ALL...


wait untill its dark outside, open your hood and start the engine. look around for white / blue or yellow flashes of light coming from your plug wires. most of the time the spark plug wires are worn out / degraded from heat , and you can see the small lightning flashes in the dark. if you see no light flashes ( shorts to ground) then you can have a cracked / faulty distributor , or bad spark plugs.

How to replace 1997 buick inition coil


I just did one the other day. There are three coils. You can determine which one is bad by using the number one spark plug wire and an old spark plug. Put the spark plug in the wire ( while it is still in the coil) and ground the plug against the engine block. Make sure it is grounded solidly to metal or you could get a nasty shock. Have someone start the engine. Look at the spark. It should be fat and blue. Turn the engine off as soon as you have seen the quality of the spark. Pull one of the wires from each coil in sequence and move the number one wire to that coil. Proceed as above. The weak coil(s) will have intermittent spark, yellow spark or maybe none at all. Once you know which coil(s) are bad remove the two small screws at the ends of the coil. They hold the coil down. Pick the coil straight up, pulling the contacts out of the ignition module. Set the new coil in place and screw it down. Both towers spark every time the coil fires so reinstall the wires in either spot on a given coil. Good Luck

Check engine light flashes spitts and sputters has low power wont get over 45 mph


Engine is misfiring, common causes are spark plugs and spark plug wires, could also be a coil, but plugs and wires are the least expensive place to start.
