Won’t Start

[mo-bronco]

I can’t get my ‘73 to start. It has an aftermarket 4-barrel that I had a shop put on. It ran fine back in the fall and I started it occasionally over the winter. Now it won’t start. I noticed that it didn’t have a fuel filter, so I put a clear filter on to see if I was getting any fuel. Very little made it up to the carb. I put a new fuel pump on it, now it has plenty of gas showing in the filter. Still won’t start. If I spray starting fluid down the carb, it will run until that is burned up. Any ideas?

Gas isn't getting from your new filter thru your carbs jets to the intake.

Sounds like you need to pull the fuel line off the carb and make sure it's getting fuel but AFTER you crank it for 10 seconds... here's why.

After you crank it for 10 sec you want to manually move the accelerator pump by hand while looking down into the carb (key off, not while the keys on to see if the accelerator pump is pumping gas for the enrichment circuit and to see if the bowl has gas.

You want to crank it so you know if the fuel is getting to the fuel bowl in the carb. After you crank it and you don't have any gas squirting into the venturis, et us know if lhave fuel in the bowl or not & whether the acceletor pump is squirting fuel.

Thanks, I’ll try that.
