Problem : cold start fine- will drive 10,20,30 minutes somewhere, turn key off, come back to vehicle10 minutes. This happens more than 50% of the time - Engine will start, shut down in 20-30 seconds**
Trouble with engine shutting down-Mr. Blue Oval, hope you may help. I have a '76 Bronco, 302 , 4b carb. MSD ignition system installed, has electric fuel pump with filter , vehicle has the two fuel tanks.*****Try starting immediately again, it will just crank, wont start up. I'll wait 5-10 minutes, it will start & shut down in 30 seconds....and so on & so on. It shuts down as if key turned off.--pulled fuel line off carb, it's squirting fuel. Did not check pressure with gauge. New plugs, wires, cap. , checked fuel lines from tank to carb. Fuse panel - says painless wiring fuse associated "ignition" is good (continuity) , wires,where key goes all connected.
