Fuel delivery?? Pump or Carb??

Well, after fixing my problems, I'm running into yet another one....

This one is going to be fun.... I got everything hooked up and set, and I go to restart her (gas tight and vacuum tight) and she'll kick over and idle for exactly
2 seconds......and then she dies.

She'll keep doing this with the choke fully closed and what's weird is, if I try to throttle her, she dies much faster than just leaving the throttle at neutral.

Pump is working cause I can hear it, and well, I can only reach the 2 otter carbs to see if there getting gas, because of the drain screws.

But I do smell gas in all 4 carbs.

I will be getting up tomorrow morning to install the gas tank instead of my shops testing gas tank. The tank I'm using is only half of a gallon, where as the VF's gas tank is like over 3 gallons.

I'm thinking the down force of the gas might be playing a huge role....????

What is the amount of gas the pump is suppose to pump per second??

And what could be the problem other than what I've mentioned??

Thanks again for all the help. I hope to be driving my very first Interceptor....not that CB400F's stink:smile:

check the fuel pump relay and make sure the pump is trying to pump fuel

you can feel it click when it pumps to by pass the relay just jumper the 2 wires together

 

Jump just the 2 main wires coming off of the pump? Is this right??

Well, I just got out of the garage. I was working on her and some how I was able to get her to start and idle, with full choke that is.

I can't get her off choke and she still wants to die as soon as I apply throttle.

Does this indicate a problem with the diaphragms on each carb, or a problem with the jets (slow and main)????

I'm heading out to the shop for carb bowl gaskets as these have a tendency to break when you take the bowls off.

I just want to make sure I get every little thing cleaned that could be causing a problem as these boots for the carbs are a pain in the butt:bootyshake2:

no no no the RELAY.
NOT the pump itself.

maybe your gen does not have one

 

Oh! The relay.... I'm sorry I must have misinterpreted that.

Now I understand....I'll try it tomorrow.

Any thoughts to the other things I mentioned??

Thanks

my 86 was like that........... I just rebuilt them and runs great now

 

the symptoms you describe suggest low fuel level in carbs ( a pump or filter problem) or clogged, dirty slow jets......

might be a good time to inspect your sparkplugs, too

Sea Foam might help.....
