The injectors pulse only with a crank signal (or running of coarse). It you stop cranking and leave the key on, the injectors stop pulsing.

I have heard countless times on HPTV and other automotive shows talking about disabling the ignition and turning the engine over to get oil flowing, to prevent a dry start.

On another note, I pump the gas in my car all the time. She starts everytime like that. I only do this on cold starts after she has sat for at least a week.

The accelerator is only hooked up to the throttle plate. You're only allowing more air into the cyl. Tapping the throttle when off doesn't send any fuel into the car.

Cranking it to oil it is a bad idea. 400 RPM'* is nothing for our oil pump.

Completely agree...You should look up startup procedures for a new engine. Granted the tolerances are tighter but the reasoning and idea behind it are the exact same. You ALWAYS want your engine started as quickly as possible.

If this actually worked all those companies that sell the expensive *** pre-lubers would go out of business pretty quick.

If this was advisable, don't you think GM would mention it in the owners manual. If it was neccassary, I suspect they would have a system onboard to do it automatically, otherwise there would be an awfull lot of dead engines lying around from "dry starts" not to mention class action law suits.

pumping fuel injected cars??....

dont know. If your sensors are working there should be no need to pump the gas to get her going although with my old ninety eight it did not like -20 too much and did need a few pumps to KEEP the engine going.


As far as flooring it to get oil moving. I dont see how this would work either.

Well, I am just saying what I saw on TV. I don't see how letting the engine crank [600rpm for me] would hurt anything, but if you say it'* bad.. then I probably should stop, huh?

Yesum, yesum yushud

on a carbureted engine with a mechanical fuel pump, its almost 99% of the time to pump the gas a few times BEFORE cranking the motor, on a cold day with a carb, hold the accelerator 1/4 way down and crank, as flooding is very common with a carb, especially one that is is a Motocraft 2150 on a 360 that is poorly in tune... .
Once your Bonneville starts after being flooded, be ready for the rich burnt fuel smell, ah how sweet it is...
lol

dont believe everything you see on tv
