Hi, dryer turns on, igniter does not ignite .tested it and shows continuity as well flame sensor. Coils test OK. Diving me nuts any help would be greatly appreciated.
Thank you so much

When it gets dirty the sensors will not know how hot it is in the air since the sides of the duct where they are attached are insulated with a layer of concrete-like (and very flammable) lint deposits. You will have to clean the drier out thoroughly. Every air duct will have to be removed and scraped and washed out to remove baked on lint deposits which is like a concrete lining. This will burn so the manufacturer has installed the safeties to keep from having a house fire. Driers were the number one cause of fires at one time. For a video to help, look at: http://www.youtube.com/watch?v=MMP7BW1lLs4 to see how. Also: http://www.youtube.com/watch?v=iBiRw-KElC4 ; http://www.youtube.com/watch?v=yFTZGgVisCI
When you finish cleaning the drier it is best to also replace the belt, too, because you do not want to have to disassemble it again, and if the belt is over two years old you should replace it. Also, you need to lubricate the bearings with white lithium grease. EVERY bearing you find should be lubricated. That means the support rollers and the center drum bearing, if it has one.

Note that on most of the videos it does not show them washing out the parts, but this is important because it's the only way to really get the parts clean, just don't get motor wet or the capacitor if it has one. Vacuum out the motor. I would move the drier out to your garage to have plenty of space to work. You also want to check your vent and clean it, also. The job is really easier than it sounds. There is no shortcut that will work; it has to be cleaned well. Just vacuuming out the dryer a little does little good. When you are done you will have a new dryer and it will dry like new again. You want to clean it like this every two years or every year with many children.
On a gas dryer you may want to clean the flame rod with some fine sandpaper. It’s a small platinum rod that looks like a spark plug and proves the pilot light is lit. It takes a few seconds to do, but will save you trouble later. Good luck and attached are some manuals: https://dl.dropboxusercontent.com/u/8010163/Frigidaire%20Dryers%20and%20Test%20Equipment.zip

I am assuming that you have no meter. You need to get one. Home Depot has some good digital meters that should do everything you need to do. Just make sure to have power off when using it in "ohms" mode. You obviously have an open safety somewhere. Start at the door switch and go through the drier until you find the open safety. It's probably a fuse mounted near the burner and you will have to buy a new one. If you skip steps you will put several fuses in before it gets totally clean, so do a thorough job the first time. Make sure to WASH out the parts, and do not miss the blower cage, wheel, and the filter holder along with the door duct work if it has it. Get it totally clean. It's very important because any place with built up lint deposits will cause a failure. Lay it down on garage floor and take it totally apart. It's very simple. Good luck.
