priming our motor after sitting? how to

[brentsGTS]

So I wann fir the viper up after a 1 month slumber and I'm not sure of the best way. I know on 03-04 cobras you can simply just hold the throttle open and it will shut off the injectors and spark so you can crank the engine without actually starting it. Does that work for the viper aswell? Did a search and didnt see anything. Thanks.

Why do you need to prime it? It will start right up and it will start up at WOT too, just will take longer to start at WOT. I have a crap load of cars, I think about 10 like a lot of guys on this board and some of mine sit for more than a month between uses and no big deal. It isn't like you let it sit 5 years-it has been a month or so.

You can install an oil accumulator and use it as a primer. I use one on my Mustang because it sits for 6 months to a year at a time.

its a car, start it up, dont over rev it and drive it. dont make it more complicated than it needs to be

I would try putting the key in and turning it.

Quickest way to get oil pressure up is to start the engine.

If you want to crank the engine without it starting to prime the system, then pull out fuel pump fuse or relay and it won't start. However, I don't see much point since your still spinning the engine to get pressure... I don't see the difference from starting it. But if you want to do this, always kill fuel not spark. Killing spark only will inject fuel without burning it.. Bad for your rings/hones and bad for the oil.

I've used accusumps to prime brand new engines before starting... I would hook them up to an oil pressure port and open it up. Then disconnect it and plug the port and fire up.

Dry sump....no worries.

This, don't over think it just start it up it will be fine. There is no difference from letting it sit 2 day or 30 all the oil will bleed out of the lifters and everything will be in the pan at that point

Do not remember if it is a Federal rule or if the manufacturer programing the computer for this, but on all my cars and other cars I heard from friends, cranking at WOT cuts the injectors so you can flush a flooded engine.

Never had a Cobra, so I am basing this on the Ford GT procedure on changing oil, but that is a full dry sump system. The lifters are hydraulic so you need to pump oil into them, that is why you WOT crank after an oil change.

just start it and let it idle, cranking it with or without starting still rotates all the internal as mentioned before just without fuel it is not rotating at 1000rpm.

What different does this make? You still are not priming the engine with an external pump.
