Hey, it is me the novice again. The '38 had been running great since we got it running in June. I had the car out last Friday for another test spin (10 miles). The car ran great. I wanted to take my wife out for ice cream Saturday. The car cranked great, but no fire. I checked the inside of the card and it is dry. The fuel pump glass bowl is full. Can the vacuum be checked without the car running? I have a hose clamp on the vacuum line connected to the carb. I checked the connection on the wiper pump and the is no hose clamp. I added one. I also checked the nuts holding the carb to the intake manifold (all tight). Next I checked the screws on the top of the carb. The back two were a 1/4 turn loose. The only gas line connections I haven't checked are under the car. I will do that when it cools down (early in the morning). I will also blow out the line to ensure it is open. Since there is gas in the fuel pump shouldn't the car start (gas to the carb) assuming not vacuum leak? Everyone has been a great help getting the '38 running since 2016. Thanks again in advance.

If it is hot where you are, the fuel in the carburetor may have evaporated out of it during an engine hot soak. Just squirt a little starting fluid into the air cleaner to get the engine started. Once the engine starts and runs, the fuel pump will be primed and the car will run fine.

Possible the fuel pump is not working properly. Should have about 2 # on your vacuum gauge with the car at idle. disconnect the fuel line from the pump to the Carb and check for fuel flow while turning the engine over. Run the pump output to a catch can to prevent a mess.

I have lost track of the type of fuel pump and the condition of the fuel lines. Could you please post a photo of the fuel pump area under the hood and where you removed your electric fuel pump.

Tom, Carcrazy and 40 Coupe, I used started fluid as you mentioned Carcrazy. The car started right away. I let the car run for a few miutes and shut it off. Because of the weather I was not able to good for a ride. $0Coue I couldn't test the vacuum as the car wasn't running. With my previous slow power issue the vacuum was ok probably less than 100 miles. Tom, all new fuel lines and the fuel pump has a glass bowl. Pictures were in an earlier post. I'll update if the car continues continues with the carb issue. Thanks All

Ray, I could not find photos showing a fuel pump with a glass bowl or showing the electric pump removed. Posting those photos will help me understand how your car is configured.

Tom, I'm looking for pics. I'll take new ones later, but here's a description of the fuel pump and electric pump. First the electric pump has been bypassed. The fuel line runs directly from the fuel tank to the new fuel pump with bowl. The fuel pump w/ bowl is in the same location as the original pump. Very simple and straight installation. I started the car and went for a 10 minute drive. The car ran great. I plan to keep the can of started fluid in the car at all times. Thanks again team!

Be careful with starting fluid. Too much of a good thing will hammer the rings out of the poor thing. If you have fuel in the glass bowl, it should fill the carb fairly quickly. We have all become too use to fuel injection or automatic chokes. Old cars sometimes took a bit longer to start. If the engine is cold. try using the choke for a few seconds, before reaching for the can of ether. Often that is enough.

Paul, we only shot a quick burst of the starter fluid and the car started right away. I started and drove the car 4 - 5 times since then with no issues. I have not used the starter fluid since this initial time. My wife bought the car for me 10 years ago and this is the only time the car required starter fluid. But I plan to keep a can handy. Thanks for the heads up on starter fluid usage.
