Gwood Posted April 28, 2013 Share Posted April 28, 2013 I have a 1949 dodge coronet. I finally got it started and let it idle for about 20 minutes. I then test drove it around the parking lot. Now it doesn't start very easy and when I do get it started it's just for a few seconds, also I have to wait about 10 minutes before I try again. Any help would be great.

Machinist_Bill Posted April 28, 2013 Share Posted April 28, 2013 3 things are needed for a car engine to run:1) Fuel2) Air3) ElectricityI would start with fuel flow such as disconnecting the coil wire, then the fuel line from the carb, and try to fill a mason jar while cranking the engine.

Gwood Posted April 28, 2013 Author Share Posted April 28, 2013 i have rebuilt the fuel pump if that matters Link to comment Share on other sites More sharing options...
Machinist_Bill Posted April 28, 2013 Share Posted April 28, 2013 Pickup screen at the fuel tank could be clogged. Fuel filter clogged. If you want to move on to the other two items it's your choice. You could grab the coil and see if it's hot. Link to comment Share on other sites More sharing options...
Gwood Posted April 28, 2013 Author Share Posted April 28, 2013 Where is the fuel filter located and does a hot coil means trouble? Link to comment Share on other sites More sharing options...
Machinist_Bill Posted April 28, 2013 Share Posted April 28, 2013 If you don't see a fuel filter between the fuel pump and the carb then you don't have one. Yes, a very hot coil is no good. I would still be leaning towards fuel delivery because it starts and quits then starts up again. I would disconnect the line as previously stated and see how steady the squirts are while cranking the engine. BE SURE TO REMOVE THE COIL WIRE FIRST!

Gwood Posted April 28, 2013 Author Share Posted April 28, 2013 I know theres no filter between the pump and carb, and the fuel tank has been professionally cleaned. I will check fuel delivery tomorrow, If that good, possibly coil or air mixture? Link to comment Share on other sites More sharing options...
Silverdome Posted April 28, 2013 Share Posted April 28, 2013 (edited) If you have any rubber hoses in your fuel line be sure they are in good shape inside and out. Sometimes they look fine from the outside but are broken down or crumbling on the inside. Also any kinks in the line or vapor locking from your fuel line running too close to exhaust or another heat source.

BE SURE TO REMOVE THE COIL WIRE FIRST!When doing cranking tests and you don't want spark then it is best to kill the spark. Removing the coil wire wont do that. Rather pull the coil wire from the distributer leaving it in the coil on the other end and ground it solidly. Then you wont have to worry about spark jumping out of the coil is search of a ground.

Gwood Posted April 28, 2013 Author Share Posted April 28, 2013 Today I got it running. I had to pour a little gas down the carb, it fire up but only a short time which told me it was fuel related. After unhooking the gas line to see if it was pumping, I noticed very little gas but then it started pumping pretty good and it was fine after that. Maybe air in the line or some debris. At this point not sure. Thanks for the help everyone, Glenn Link to comment Share on other sites More sharing options...
Phil 32DL6 Posted April 29, 2013 Share Posted April 29, 2013 Make sure to check that the gas cap is venting properly. Link to comment Share on other sites More sharing options...
JACK M Posted April 29, 2013 Share Posted April 29, 2013 If it still acts up you most likely will find an air leak between the pump and the tank. You wont always see fuel leaking out where air may find its way in. Link to comment Share on other sites More sharing options...
