Change the CAD flame sensor, it's a $3 part and they are all the same, just the mounting is different. Put it on your mount and sould be fine.

I need a fuel system diagram for a 2000 ford windstar se 3.8

If it runs fine down the road, the fuel system is OK. You most likely have a dirty throttle body. Get a can of brake clean and a toothbrush. Remove the air filter plenum. Open the throttle and clean it the best you can. The back of the throttle plate and where it sets in the throttle opening. Then use the brake clean and spray down the MAF sensor in the plenum, both sides. Start the van(it will take a second or two to start). Rev it up and spray some brake clean in the throttle.
Put it back together. The engine light will be on because of the MAF sensor not being on the throttle when it was running. It will go out soon. Or turn it off with a code reader.

Won stay running

Check carburetor & air filter. Clean off all dirt and clean air filter. check age of gas. Cannot be more than 30 days old. Make sure to use fresh gas w/synthetic 2-cycle oil @ 40:1 ratio (1 gal.) Gas to 3.2 oz. Oil). Do not use old or stale oil/gas mixture. Before putting in fresh fuel, press the primer several times. A small amount of gas might show up in the fuel tank. Remove fuel. With carburetor cleaner, spray carburetor. Put in small amount of fresh fuel. Just enough to cover the fuel filter. Then press primer with fuel cap off, and watch to see if fuel is flowing smoothly. If not or if plastic primer bubble does not come back to original shape after pressing, then you have to take carburetor apart and clean or get new carburetor.

Weedeater PE550 will not stay on. Prior to placing this unit in long-term storage, the unit worked. Since pulling it out for this season, it would not start. I replaced the fuel lines and primer bulb. ...

Is the smoke coming from the spark plug hole or just near it?

There are three things that you need for it to work.

Fuel, air and spark.

If you are missing any one of those things, or if one isn't optimal, it wont work well if at all.

You say spraying carb cleaner into the chamber lets it start, but after a minute it dies?

That tells me you are getting a spark.

Have you taken the carburetor out and cleaned it thoroughly with carb cleaner?

Often when fuel sits around inside a carburetor it can build up gunk and make it not function properly. I recommend removing the carburetor and taking it completely apart, cleaning everything with carb cleaner and putting it back together. It sounds difficult, but I promise it is not, just take pictures to help you remember how everything goes together if you want.

Also while you are at it either clean or replace the the air filter, that should help as well. If its a foam filter you can clean it with gas, if its paper, just buy a new one.

The heater will not light the kerosene starts then the ignitor lights then shuts off I tried repeatedlyto fire it no luck I think it might be an air adjustment

Here is the manual that will help you sort it out.

I think you have a photo cell or fuel issue as it ignitor trips but you do not get fuel.
Make sure you check the seal in the tank cap (Closed tightly) and the 2 hoses from the tank for cracks. The fuel system works via the 2 tubes. One is pressure the 2nd is fuel supply. Any leaks via either hose or the fuel cap will prevent fuel flow.

You may have to clean the fuel nozzle also. Just make sure to clean the photo cell carefully before putting it back together.

Unless you have an air filter(s) that is horribly clogged taking care of the above should get you going again.

Thanks for choosing FixYa,

It is full of kerosene however when I plug it in to start, it will not turn on. It makes the effort for about two or three seconds then turns off

The safety is turning it off because it is not lighting. You did not mention if it was actually trying to light, or if it was just the motor running. If it is not lighting, take the top cover off and watch the ignitor. Depending on the type of ignitor, it will either glow or spark when you plug the heater in. This should happen before the fan starts running. Once the fan starts, you should be able to see a mist of fuel coming out of the nozzle. If there is no fuel spray you may have an air pump problem, which is on the back of the motor, or the fuel screen in the tank may be plugged.
1. Check for ignition source
2. Blower motor should start, if you have ignition
3. Fuel should spray out of nozzle, if not check filter and check for air flow out of the pump.
4. If you do not have any air flow, or not enough air flow check the pump. Pressure out is critical.
5. If pressure is too low check for leaks around the pump. Spray soapy water on the back side of the motor/pump housing. The plastic pump cover is bad about cracking, and the cracks are very hard to see. The plastic cover could also be loose on the pump.
6. While on this end of the pump; the filters need to be clean, as they will affect the pump pressure and upset the whole apple cart.

I HAVE A 115,000 btu Keroscene heater. It just stopped running.

Take the top cover off of the unit. Plug it in and look inside the burner can to see if the ignitor is glowing. If not you probably need an ignitor. You can remove it to check the heating element to see if it is intact, but be very careful, it is more fragile than glass. If it is intact, you may have a control board issue. The ignitor should glow before the fan starts. Be careful to stay away from the fan blades while doing this. If the ignitor glows, and the motor starts, you should then be able to see fuel spraying out of the spray nozzle. You may need a flash light. If the fuel does not spray out of the nozzle in the correct amount, the unit will shut down. There is a photo cell that detects ignition. If the fuel pattern does not look even, you could have low air pressure out of the pump, a dirty fuel nozzle, or a plugged fuel screen inside of the tank. The air pressure comes from a pump on the back side of the blower motor. Insure that the filter are clean on the pump; there are three of them, and the plastic end cap needs to come off to access them. If they are dirty, they need to be replaced. The air pressure off of this pump is very critical to proper fuel delivery. The rated output pressure of the pump is on the heater data plate. You will need a low pressure air gage to check this pressure. Another source of low air pressure is the plastic end cover over the filters. They tend to crack with age. Spray soapy water on the end cap while the blower is running to look for leaks.

When start go to rev it just dies

Remove the throttle stop adjuster and the air screw adjuster and spray carb cleaner in the holes.
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Turn the pilot screw 1/4 turn counter clockwise. Check the float level. Before putting the slide back in the throat of the carb, move the clip on the jet needle one notch lower.Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Adjust the idle speed with the Throttle stop screw. This process should get you back on the road. A “very helpful” rating for this answer? Thanks!

If...the air pump pressure is right, the ignitor glows, the fuel is hitting the ignitor, then the unit will have combustion......unless.....
  1. there is an air leak on the pressure line
  2. there is a vacuum leak on the fuel line
  3. there is a leak at the nozzle adapter
  4. there is a restriction either in the nozzle or the fuel filter
  5. the nozzle is worn and is spraying fuel rather than fogging fuel
