i have an 1940 truck 1 1/2 ton 95 hp and i have got runnings problems warm days
first i thought it was hot fuel with gas in the carburator
but the electric pump will stop, the truck are not going to start, seams dead.
a friend told me to check the circuit braker.
First of all, where's your electric pump wired in?
Am I correct to understand that the starter engages and the engine is turning over? And it just isn't firing? You may want to check for power at the coil. There's a chance that the electric fuel pump is wired to your ignition switch, which would make sense if your switch was bad. I would be checking your ignition switch and going out from there.
