Hey drivers,

I am going to turn the key on Thursday or Friday of this week on my build.

Before I fire her up, I need to prime the new engine, turbos, and oil cooler.

I need to know which fuse to pull to ensure that the injectors will not be pulsed.

ECM fuse behind the battery?

Pull the injector harness connector? (that would be way more convenient for me)

My goal is to crank the car for a few seconds until the oil light turns off, then a few more seconds after a short wait. The engine was shelved for a few years so there is probably some dust in there, and I did my best to get every chip out from drilling into the upper pan for returns. You guys know the drill.

I plan to run it for a full temp cycle, then drain the oil and change the filter. Then I can go have some worry free fun. Cheap insurance if you will.

Let me know if one of you knows how to accomplish this safely with no risk of the injectors opening. With my new RFS I could dump a lot of fuel quick so I want to avoid washing the walls of oil. I lost my last engine to low compression so I'm going to be pretty up tight with this one aside from the fact that I am going to be forcing air down its throat against its will.

Anyone, need a solution by tomorrow night thanks!

 

mike try fb too. may help get you a quicker answer

 

I did lol, I take it with a grain of salt when I get a reply on FB. Nobody had a solid answer there though. Just bumped it.

I am thinking I can't really go wrong if I pull the injector harness plug. I believe the knock sensor is on its own connector so I would just be isolating those but I need to double check that one.

Thanks Jersey

 

If there is a fuel pump fuse, unplug that fuse. That's what I normally do on engines when I want to crank, but not start.

 

I'm going to be doing some fuel system testing prior to cranking so I can't do that since I will already have line pressure. I wish I could, I usually do that too.

I believe that if you push the accelerator to the floor while starting the car, the engine will turn over but not start.

 

That's either one hell of a toll, or some really sweet insight...

Spark or fuel cut?

Wait...........

I'll just contact my tuner.... And have him throw on a no start map on the base-map too. Duh

 

bigc is correct.


hold the accelerator to the floor when you crank and it will not start. it doesnt let the injectors pulse.

 

Great thank you fellas, it does make sense

 

I'm crankin' and crankin' and no oil pressure is building. I filled my oil cooler up to the top and poured some into the oil cooler lines also. No oil up top at the VTC solenoids although the engine started spinning over significantly smoother after a few seconds of cranking. Will I be able to build pressure without it firing up? Is it air locked or something similar? Oil light is still on too.

 

I don't think you actually build pressure. You're basically just priming the system so oil is available when you start it up.

 

correct. you will not build any oil pressure off cranking.

it is simply to help oil the system before starting.
although, on startup at idle it will oil your system very quickly. so now that you have cranked it a few times. just start it.

 

I dunno man^^ haha. I pulled the plugs, then cranked for 20 more seconds. Oil light is off now, sounds smooth and good to go!!!
