best way to turn over engine without starting it

remove the fuel pump relay, there are 2. for lh and rh fuel pump. both behind seats. which side? i forgot.

or remove all 8 coilpack plugs (not recommended)

or remove all 8 fuel injector connectors ( more difficult than other methods)

or just wait until the red immo light flashes on your dash

 

I’m no pro. With that said Just start it. You are thinking to much.

I don’t understand what the point is? The engine parts are In contact and sliding and rotating either way....Whether it’s you cranking the engine to lubricate it or there’s combustion inside the cylinders moving it to lubricate it.

 

agreed! I had a ferrari sit over 2 years with old gas. I cranked car then turned off key before it started twice then fired it right up drove to gas station for some new gas to mix with the old. No problem at all.

 

If that is your real goal just leave the immo activated. It will crank but won't start.

Having said that, I agree with others Just start the car

 

I totally get this, I like to turn my cars over till the oil pressure comes up before starting them when they've been standing for a long period, but cant see an easy way of doing it on my 430. I'll be interested to see what other replies you get.

 

I'm just confused what purpose does this serve? There's still as friction and rubbing if the engine is turning over whether there's combustion present or not.

 

It gets oil around the engine to lubricate the parts that may have become dry due the long standing periods, rather than going straight to 1500 revs on start up. Something I've always done.

 

Yes, but think about the logic behind it. The un-lubricated parts you are worried about are moving regardless of whether the engine is actually idling or not. And the oil pump flow is much lower by just cranking for a few seconds vs. actually firing up and letting the car idle.

That said, if you are actually worried about it, pull the fuel pump fuse(s) and crank for no more than 10 seconds at a time, with rest periods in between to keep the starter from overheating.

Better to just fire it up.

 

Or if you’re really worried, you can get oil pressure accumulator kits, so that you can prime the whole system before the engine even turns.

I think maybe there’s a marginal benefit from turning the engine over on the starter at say 700 rpm, versus a cold start where it’s straight in at 1400 rpm. I still wouldn’t worry that much. Just fire it up!
