Dryer won't stay running

You may have a loose (disconnected) wire that is supposed to go to your sensor bars.

Pump is only supposed to run a few seconds to prime system with key on. Should run in start position, but check for restricted fuel filter and for bad fuel pressure regulator.

Don't really understand your question but the fuel pump is suppose to run when you turn the key on. Runs for a few seconds to build to the proper pressure and then shuts off until the pressure is needed again. In most cars it will cycle every time you turn on the ignition switch.

This is normally due to either a clogged intake filter, or water in the fuel. To rinse the intake filter and the tank, put in a quart of fuel and shake, shake, shake to rinse crud off filter and dump out. Otherwise you'll have to disassemble to get to the filter. To remove water from fuel, dump it into a bucket. The water will coalesce in the bottom, then pour slowly back into the tank, leaving the 'bubble' of water in the bucket.

sounds like antitheft system is acting up..needs reprogramed maybe..pull the negative cable with the key on....kills everything..then shut the key off..reconnect the negative.. turn the key to run position for a few seconds(resets all factory presets) see if it will start..

It sounds like it may not be getting enough fuel to the carb(s). Check to make sure that fuel is flowing from the tank. If not, it may be a problem with the petcock or the vents on the gas cap may be clogged.

Post some pictures of your pilot assembly. I think this might be one of them spark sensor deals where the pilot lights and then detects flame then relays that back to the control for igniton verification. OR just try and clean up the electrode with steel wool and see if the flames stays lit is what I would try.

The weight of the wet cushion broke the drum belt. A good handyman can do it or, it's not a terribly expensive service call.
