Runs great and restarts when warm but when it sits for a day or two I have to spray starting fluid.Replaced plugs, wires, cap rotar, coil and still hard to start. 1967 /dodge 360
Sounds like it could be a carburator issue. Fuel could be leaking out of the fuel bowl or back to the fuel tank. You can tell this if you have the breather off and *before trying to start the engine* operate the accelerator arm on the carburator as you look down into the carburator. If the fuel hasn't leaked back you should see it shoot some fuel into the carburator. Also could be a fuel pump problem where the pump lets the fuel leak back and there isn't fuel there to pump up to start the engine when it's cold. Also the 360 wasn't released until 1971 so it's pretty safe to say it's not a 1967 or not a 360.

Best to do a fuel pressure test, pump might be weak and dosent show up until it gets gets warm. Best to do the test after it quits again when pump is at its hottest. If you havent done it yet chg. fuel filter too.
SOURCE: Won't start
take a little bit of starting fluid and spray into the air cleaner and try starting it. if it fires this way you have a bad fuel pump. and also take the cap off and spin the motor over to see if the rotor is moving because i have seen the distributor shafts in these older trucks break off so they will not spin

If you can get a fuel pressure gauge, check and see if the pressure is 16 to 24 lbs after the engine has warmed up.
I would connect the pressure gauge when the engine is cold, make sure it does not leak or touch anything hot, place the gauge between the hood and the windshield and drive the vehicle until it is at the temperature you feel it "starts hard". Shut the engine off and try to repeat the no start or hard start and make sure the pressure is correct.
Also, when you shut the engine off, watch the pressure and make sure it holds and does not drop to (0 LBS) of pressure.
One last question, has the fuel filter been changed in the past 30K.
Let me know.

If the engine seems to run fine over 1450 RPM maybe there is a vacuum hose leaking or EGR valve is slightly stuck open. Any help from the OBD II trouble codes? Or is there simply no MIL and no stored information in the OBD II computer read at the local parts store through the connector by the drivers knee?
