Its possible if you have a carb instead of fuel injection.
The engine would stall and have to sit for a while to cool off before restarting. The carb would in effect run out of gas.

SOURCE: How to remove ignition switch on 1986 P30 Chevy

1. Turn ignition switch to off position and leave the key in the switch.
2. Disconnect the battery.
3. Take a small diameter. paper clip and insert it into the small hole in the face of the ignition switch. You will feel a small button that you depress.
4. While depressing the button, turn the key to the accessory position (counter clockwise) and using the key remove the cylinder.
5. You can now remove the bezel by unscrewing it CCW.
6. This will allow you to remove the ignition switch from the dash and disconnect the wire harness plug from the rear of the switch.
7. They don't always come apart easily , and may require some Jiggling of the key and the wire.

1979 Leocraft Motorhome. With a 454. When the engine gets hot it stops receiving fuel. Any ideas? Changed fuel pump and collapsed fuel line section.


Sounds like vapor lock. Vapor lock happens when the fuel in the lines gets way to hot and boils/vaporizes and causes stalling . Have the fuel lines wrapped in an insulated wrap or relocate them away from heat sources. Sometimes winter grade gasoline will cause this also.

1994 chevy p30 motorhome 454 gas where does the engine come out of? Front? Inside ? Underneath?


If it does not have a front radiator support that unbolts and can be removed in the front then you will need to remove it out from the inside dog house cover area. We removed the transmission from the back and slid it out that way. Good luck.

I have a motorhome make Honey 421S with a chevy 454. the choke light stays on, and it smells like a gas station after a ride. Consumes lots of fuel and I don't understand the vacuum system. Anyone can...


Update? If the Motorhome has a carburetor, its pretty old and has a P30 chassis. Gm makes the truck, Honey makes the camper. Check the electric choke and make sure it has power to it when the engine is running, if not check all fuses. I dont have a diagram to see where the choke gets power from. Make sure the choke pull off is working, its a little vac can on the right side of the carb, if it leaks, it wont pull the choke flap open. Anyone that works on Quadrajet Carbs can fix it for you.
