Jimmy James! Stop reading right here.

We all know you would die a thousand deaths if you got a grease stain on those dad sized light tan Dockers or the white short sleeve shirt.

I am just about to complete a head gasket on a 97 Dodge with fuel injection. The injection has been sitting on a bench(kitchen table) for a couple months. Does the fuel injection system need to be bled or can you crank and get gas to the injectors? The manual does not address this issue.

You should be able to just crank and get fuel there. If the Dodge has been sitting for a few month's though it's possible your gas in the tank could be bad but if the gas is still good it should be no problem.

You might need to crank a bit though or cycle the key multiple times with a few seconds between each cycle.

Not sure of the state of your battery after sitting for a few months, but that might be a consideration - especially with the extended cranking.

Might be a good idea to leave it attached to a charger during the crank-fest.

Thanks for the 411. This is the first electronic gas fuel injection I have dealt with. I have done diesel mechanical injection where you have to bleed all the lines.  I am hoping the fire up the engine in about 2 weeks.

Do not do this. I've seen it cause the battery to explode.

Some injection systems have to be bled. In many cases there is a fitting placed high on the assebmly for this purpose. For others you have to bleed by loosening a fitting until the air is purged. Some require no bleeding.

Just google "fuel bleed *your engine model*"

i've started cars this way, but the charger i have has a switch position for jumping a car.

if you're wary of it, you could give it a good charge now, then hit harbor freight or someplace and get a cheap float charger so the battery will be ready when you need it. it'd be better for it anyway, especially if you happen to be in a cold location.

If the gas isn't bad (which if so it'll smell funny ) then it really should be no problem at all assuming the pump didn't go bad (again from bad gas). It should just fire right up. I've never seen one that had to be bled yet but that's not saying perhaps a shop manual specifies bleeding it but it's just never really necessary in my experience. We don't do a lot of deisels but in the past years ago when we got like maybe one or two a year and when it came time for servicing the filter if you didn't fill it up with deisel then it'd be a PITA to get started because of air. Gas engines once they build up pressure (which should be a turn of the key unless you've changed the filter then maybe a few key cycle to get head pressure) it should just fire and idle.

I've seen a battery explode from being on a charger when the starter was engaged, I was standing under a car in the next bay when it blew. It exploded like a large plastic grenade filled with acid might. The bang was deafening, and acid went *everywhere.* Be safe, turn the charger off before putting a load on the battery.

Because it's bullshit, at least for a gas engine.
