the plugs are sock in gasoline/petrol so my van misfiring

After I turn off the engine and restart the siren stops but starts again within a minute...this is a conversion van and I think a 1500 but it could be a 2500. I cannot find the fuse to see if it is loose. I checked the ground wire from the battery to the body under the hood.

Still having trouble, brake lines is full of brake fluid in front but still line not holding any pressure. Brakes have been pumped and bled.. Need advice??

Happens on every shut off

My 2004 chevy express dash light goes hot while highway driving with the AC on. It goes out when AC is turned off. Outside temps are high. Don't use if not, so I don't know if it occurs if used while outside temps are low.

I was heading home when suddenly It began to backfire and recently we changed the hose from the gas pump what could it be???

Have looked in every place Ive been told it should be but cant find it. I cant find any diagrams or video showing me EXACTLY where the drain tube is located.
