Trouble getting 76 pickup to start.

[Migeo]

Hi
First of all I've been here for a bit and like this forum.
This is our truck
A 76 chevy 4x4 shortbed


And this is the carburetor we have installed


Now the problem is it wont start unless we put gas into the carb directly but only for a moment.
Heres a video I took in case your interested

Do you have fuel pumping into the carb?

Thanks for reply

It does pump gas but we were thinking it might not be enough going thru.

Do you have a fuel filter in between the pump and carb? If you do, check the filter might be clogged. Fuel line between filter and pump could be clogged. Fuel pump could be on uts last leg...

Check your fuel lines for a clog and check your fuel pressure. But first make sure you hqve gas in your tank. Single or dual tanks?

Yes

Does your switch between tanks work? Before yoy start spending money see if your pump is any good...take the line off the pump assuming its mechanical and have someone crank the engine 2-3 times see if any fuel is coming our of the pump.

Is it a new carb? Have you changed the ignition? Anyback fire through the carb could cause the accelerator pump to go out, AkA it won't want to idle

[motornut]

remove power to coil, before checking pump
clean out line from pump to carb(mine was fulla rusty crud)
confirm no breaks in gas line to tank...can you blow bubbles by mouth SLOWLY into tank?
consider running line into a portable can from pump to eliminate poss tank issues

Thanks for the advice guy but my dad has made up his mind and wants to buy a new fuel pump. Cant change his mind so now we wait and see. Will post update later.

Thanks.

Hi again.
It turns out that the people o'reillys auto parts told us that the fuel pump seems to be in working order(it is 5 years old and hardly ever used).

They also said that it could be that there might not be enough gas in the tank to create enough pressure for the pump to push gas all the way to the carb. So that is our next little thing to do.

Ill keep you guys posted and thanks again.

You could add a couple of gallons in and try it but I hardly doubt it...let us know. We'll walk you through it step by step.

Thank you guys for your help so far.
I really do appreciate it/
But we havent been able to progress much due to missing funds.

Although we did come op to another problem which is that this piece is loose

do you guys know how i could raise it even if i have to buy something?

I was thinking of something like this but i have no way of cutting it


Thanks again for all your help.

Sorry not being able to reply but nothing has happened until today.

One of my dads mechanic friends came over and had some ideas on what was wrong. It turns out that the switch that controls the tanks was not responding. So the went under the truck and manually switched the tanks. So here's a video of it if you guys want to watch it.

Chevy finally on

It only took a new fuel pump and new hoses.

To bad I still have the passenger cable problem

Sorry once again sorry for not replying but that's it

That cable is the kickdown cable some leave it hanging (me) and some connect it
