I have change the ,electric eye ,nosel,coil, fuel valve,i have spark,fuel no fire
If this is a fuel oil burner in a residential style forced air furnace, you probably have the electrode adjustment wrong. The generic measurements for the electrodes for an 80 degree hollow fuel flow atomized mist spray is 9/16" above the center of the nozzle, 1/8" gap, with a leading dimension of 1/8". Because the atomized mist leaves the nozzle at an 80 degree angle, electrodes protruding too far out will be drowned out by the fuel and not ignite. Electrodes not extending out far enough may cause a serious delayed ignition that will rock the structure, or not light at all because if the cad cell doesn't react to the UV rays of a flame, it locks out the ignition control.
When in doubt, its always back to basics first. If this is a torpedo style heater, it may or may not utilize the two electrodes for ignition as noted above and may just use a spark plug style ignition device, in which case the above dimensions are rendered useless.
Testimonial: "it has a new coil , new spark plug ,new eye , fuel valve, when i have the cover off it has fuel and spark it looks like its ready to firer just doesn!t u can see it trying but wont if you want you can call me at 8604858535 my name is brian"
First you have to determine weather you
have a FUEL problem or (ELECTRICAL)Spark problem ??
Pull the coil wire off or a easy to get
to spark plug wire, Lay it close to were you pulled it off of (Do not
hold or touch you may get SHOCKED) and crank motor (need two people)
look and listen for a spark, if you see or here a spark, then go to
next step which will be to check for Fuel (gas). Be very careful when
checking fuel, as most lines are under pressure and may cause bodily
harm such as BURNS to EYES and SKIN!! Loosen or pull the inlet fuel
line off and put rag over line. Some fuel injected vehicles have a
fuel rail the has a valve that looks like a tire valve. Put a rag
over this valve and push it in with a small screw driver and have
someone crank motor a couple of times to see if fuel is coming out.
If NO Spark---Could be a lot of things
Points (older vehicles) Modules, Coils, Crank Sensors, ECT......
If NO Fuel---- Could be Clogged fuel
filter, Fuel Pump, Fuel pump Relay, Fuse, ECT..........
Hope this helps you ??
