Can 355 ignition be disabled while allowing to crank ?

my challenge car with motronic 2.7 spend the winter stored away.
when I will start it up, I would like to crank it a bit without firing so the oil pump can relubricate key parts before it goes.
Do the expert on the website know a way to do it ?

 

Sure you can, disconnect the coil packs left and right so the car receives no spark.

Yup what elliot said.

 

Totally not required.

 

Yes I agree just answering the question

 

You have a dry sump you can install a pre-oiler pretty easy. Very good option especially after a long cold set.
Bill Jenkins built some really effective ones way back that stabilized engine temp while in the pits.

 

why are you saying this is totally useless ?
Do you think the oil pressure builds up immediately ?
Just asking

 

The oil film does not leave the components in 6 months and yes, pressure builds quick. I leave my car sit for 6 months a year, come spring, I start it no issue. Being doing that for 5 years in my 355 and many years in other cars. Same goes for doing oil changes, granted, a bit more film then.

 

Useless is a strong word i think itwas "not required".
As Tim suggested others have done it and said how.
Its kinda overkill but it certaainly wont hurt it.
Especially with the newer oils

 

Advice I have been given is to remove the fuel pump relay or the fuel pump fuse and crank the engine, apparently preferable to disconnecting the coil packs from the Motronic(s), which can be damaged by firing without a load ( coil pack) attached.

Just follow the procedure for doing a compression test. You don't want to be dumping fuel into a cylinder w/o spark.

 

Do not disconnect the coil packs unless you want to wash the bores with fuel while turning the engine over. I would remove the fuel pump fuses.

 

ok fuel pump fuses seems a much better idea then.
Will check where the passenger footwell fuse box has been relocated in the challenge as it is clearly not in the original position
Thank you

 

I thought some true challenges had a switch that had to be turned on before starting.

 

Guys - lets apply some common sense....

If disable fuel and spark and crank the engine - guess what, you are relying on the oil film in components prior to oil pressure.

Many use assembly lube when rebuilding a motor. I have news for you - I worked at GM's largest engine plant, they did not use assembly lube (I still would)

You simply don't need to oil prime on a car that has sat for 6 months.

 

I did not say it but I meant fuel pump switch

 

If we apply some common sense the entire idea doesn’t make any sense at all.
What do you think you would be accomplishing? Your oil pump is going to take X number of revolutions to pump oil throughout the engine anyway. Everything will crank dry the exact same number of revolutions to get the oil where you want it to be. Only it will take 10 seconds with the starter cranking it instead of 1 second for the same revolutions if it started. Being that the oil pump is not a positive displacement pump it will probably actually take longer to move the oil due to inefficiency at slower speed.

The only thing that would actually do what you want which is to lube everything BEFORE cranking is what Tim said and install a pre oiler and get the oil there without cranking the engine. Anything else is futile and pointless.

 

Being a twin rotary gear type, the oil pump is a positive displacement type. I agree that it is probably unnecessary (after about 6 months of sitting) but cranking the engine with no fuel to build up oil pressure before start, as supposed to starting straight away, is easier on the "dry" crank bearings as there is no combustion impact on them. Otherwise, the pre-oiler (like Accusump or an electric pump) is the right solution if one wishes to prime the oil system.

 

Here is a thought. If it were remotely necessary, Ferrari would say so in the manual. There would be a "Starting after prolonged storage" section.

 

To make it even more easier on the crank and drastically raise the rpm during start; remove the sparkplugs also and put a little oil in the cylinders. I do it that way, but only after an engine rebuild .
Don't forget to cut the fuel for this because of fire hazard !!!

 

It's called "towing and breakdown" section

 

My manual doesn't seem to have that section. Does that mean my car would break down?

It does have a heading under Controls-Driving Instructions titled Towing Eye-Blot. It says "Remove the protective cap B before screwing in the eye-bolt A". I guess that says something about what Ferrari thinks the average intelligence of a Ferrari owner is.

 

I can not comment onthe average intelligence because i did not realize I had dash light dimmer for moe than a year.

 

What? We have dimmer?

 

Reminds me of an old Gallagher about the stupidity of TV programs and TV controls. "They have a dial marked brightness, but it doesn't work".

So Ferraris have a dial marked dimmer, to dumb down the driver?
