Hey guys,

OK. Did the FI to carb swap. Got the car started but will not stay on. I did swap the electric fuel pump for a mech pump with a pickup in the tank. The pickup is used and the pump worked just fine on the previous vehicle...just last winter. It also has the Q-jet as well.

Now, engine will crank...sputter...start...then die. It will not stay on. It seems as if there is NO fuel getting to the engine. It is minimal from the Q-jet. I figure it is the pickup...but does it really do anything to break.

What happens if a tank pickup is bad? How do you know?
What are signs of bad/clogged/stuck Q-jet?

Trying to figure out whether it is the carb or the used pickup.

Thanks,

(hey five7kid...appreciated all your help before...will have more questions for you after this)

 

when you say the pickup is used, do you mean the sender assembly as a whole?

try unbolting the fuel line from the carb and then cranking. See how much fuel is coming out. You should get a steady interval of pumps as the fuel pushrod rides on the cam. I would put my money on a bad fuel pump. The next best thing is to disconnect the fuel line at the pump and the tank and blow compressed air to determine how free flowing the line is.

 

Great advice. I will try it soon.

Yes, I meant the whole pickup device that sits in the tank.
DO those go bad? If so, what are the warnings????

Thanks,

Check the condition of any rubber fuel line hose on the feed side of the fuel pump. These joints can collapse, blocking off fuel flow to the pump. Especially when they get hot.
