Starts up in am after drivimg an hour shut off
It sounds like the carburator needs to be rebuilt. If you have to hold it to the floor to get it to start that means it's flooded. So, the carburator is leaking gas into the engine when it's not running. Are getting poor gas mileage too?
Its not getting anyfuel to the fuel pump
The fuel has to be drawn to the pump with vacuum made by the fuel pump. Disconnect the feed line to the pump and install a vacuum gauge, crank the engine over and see if it has 8-10 in of vacuum. If not the pump is not working properly. If it does, check the fuel lings that go to the tank. If there is a crack, it will not pull the gas to the pump(like a straw with a hole in it). If that all looks fine, you may have an obstruction in the tank. Back flush the fuel line with air and listen to see if you can hear air of bubbles in the tank NOTE if there is a lot of fuel in the tank,some gas may splash out. If you hear air, Blow air from the tank forward to the disconnected pump feed line. If there is fuel in the tank it should flow out. If not you may need to R&R the tank to find a problem
I got help with fire order on block now what is
Below is the firing order diagram for your chevy. I am assuming it is a V-8. If it is not, let me know.
The #1 spark plug wire starts in the 5 o'clock position in the diagram.
Good luck, hope this fixes it.
