My 528 Hemi is a pain to start if it's cold. If it's been setting for a while, I have to crank forever to get it to fire, and usually by the time it does fire a couple of plugs will be loaded up and it will run rough for a few minutes. I have an electric fuel pump so the bowls are full when I go to start, and I have a manual choke but I have to pump and pump the pedal to finally get it to fire.

The accelerator pump was squirting fuel. No start. So instead of cranking and pumping I poured a little acetone in each of the barrels. Hit the starter and Boom! it fired right up instantly hitting on all cylinders.



This whole statement is oxymoronic, it makes no sense. It should start, let me give you a example. Between my to old cars, 383 & /6 that have mechanical pumps. If I let them sit for a couple weeks, I will either crank the snot out of them to prime the system, or give a shot down the throat and fire immediately. A friends 383 had the same issue till he added a inline electric pump, along with the mechanical pump that he only uses to prime before start. Turns the pump on for a minute or so, you hear the pump load up when it pressurizes, couple of pumps and boom. Maybe you need to wait a minute or so before cranking to pressurize yours? That or there's another problem somewhere? Anything that's flammable will work, I've used lacquer thinner, grain alcohol, lighter fluid, gas, etc. to answer your question. Good Luck
