Engine Won't Turn

[Boston]

How old is the gas in the tank?

Have you checked the fuel pick up in the tank? have you blown out te fuel lines? have you disconnected the fuel line and cranked over the engine to see if it is pumping? How about manually pumping the fuel pump? there are a few things to start with, let us know if you can't figure it out after doing these steps.

Disconnect the fuel line at the carb and put it in a clear jar. Pour the gas in the carb and start the truck. Is there any fuel coming out of the disconnected line and into the jar? Start there and work your way back.

I'll try the clear jar trick. I've installed a new fuel pump and replaced the fuel lines. The pump is pulling gas out of the tank and into the sedimeter on the new pump but, it must not be sending it up to the carb with any real volume. I rebuilt the carb this afternoon and that didn't fix the problem. It was pretty dirty so not a waste of time but, I thought that would do it. How much "pulling" of the gas does the carb do vs "pushing" by the fuel pump. I can feel the pressure coming out of the fuel line when I pump the manual fuel pump lever but, the gas obviously isn't getting to the carb.

If you find you're not getting fuel to the carb, you can grab a generic high volume low pressure electric fuel pump at Napa. Write it up and see if that works. Several people have found new mechanical pumps failing out of the box or within a short period of time.

IT'S ALIVE!!! Well, after much tinkering and a good fluid flush of the fuel system, the bad boy has finally fired up. Thanks for all the advice and ideas. I was so excited that I drove it around the front yard. Now I need to figure out why it won't start unless I run a direct wire from the coil to the battery. I'm afraid I need a new ignition switch. The lights work but, I can't start it without bypassing everything and going straight to the battery. Might need to start a new thread.

Check the connectors between the coil and the starter switch. Blown fuse?

trace the white wire that is supposed to go to the coil back to the ignition switch. It is either connected to the wrong prong, or the ignition switch needs to be replaced. Nice work on getting it running!

Great job on getting it running. A little advice though. Make SURE the tank and lines are good and clean before you run it too much more or you will be doing this all again in short order. You do have an inline fuel filter right? Get a couple spares just in case, they are cheap and easy to change so do it often until you're sure the system is clear.
