Underfuelling? 2nd injector not firing?

That's just a guess though.

If you're running an MF2, it must be set up on a rolling road. As quick as you can, before the engine eats itself.

He has no second injector Fingers look here:

https://www.fiatforum.com/cinquecento-seicento/314584-update-my-turbo-cinq.html

He has no means of adding any extra fuel whatsoever, not even a rising rate reg and an upgraded pump which would be the minimum on a low boost. :shakehead:

He simply hasn't listened to a word anyone has said so I'd not waste any more of your energy tring to help the guy unless he changes his attitude.

It's running lean! :bang:

It runs better when cold because of the fuel enrichement (pseudo choke).

It will still be running lean even when cold. You have probably done untold damage to the engine already and I'm certain it will be getting very hot.

Either find a way of adding extra fuel like everyone has already sugested, or give up and stop wasting all these helpful peoples time. If you don't listen you won't learn!

:yeahthat:

 

[djindiano]

i am lesing to what yous are saying im just waiting for money then il be getting the parts i need

 

[fingers99]

Just park it for now, before you swcrew the engine. You need the parts and some rolling road time.

what do you mean it will be getting very hot ? and at the minute im looking for a fuel pump for the car any ideas and one to use ? ( punto gt ) ?

at the minute all i have done with the car so far is fuel presser reg and thats it but i hope i installed it the right way and what do i set it to ? like what bar ?

It will run lean, hence very hot, hence holes in pistons, etc.

Do a search for J333EVO's post on how to arrange a supplementary regulator -- you need both the supplementary one for the 2nd injector and the original one for the stock injector.

Punto GT one will do fine, but I'd buy a new insert (Google for fuel pumps).

 

[djindiano]

So I have to run to regulators ? One to the standard injecter and the second injecter

 

[fingers99]

Yep. A search here will find the diagram.

 

[blu73]

they are not hard to plumb you just have to remember they regulate whats upstream of them (ie. between the fuel pump and the reg, NOT after the reg). Therefore you need the regulator for the 2nd injector between the fuel into TB and the t-piece for the 2nd injector. Make sense?

Ye I get you but what I can't understand is when I take my intercooler pipe off there is still no power I'm gonna do a compression test on it this week to make sure I did no damage to the engine

 

[djindiano]

i did the compression test from right to left and the readings i got were : 205 psi , 190 psi , 205 psi , 210 psi

could that be a headgasket problom or pisston one ?

 

[fingers99]

More likely to be valve or piston tings I'd think.

Do a dry compression test, followed by one where you put 5cc of oil down each cylinder through the plug hole (a "wet" one).

Report back.

I need to ask one more thing were is a good vacuum sores for the dump valve and boost clock feed ? Because I have my dump valve on the little breather at the back of the throttle body and it wasn't working after I boosted and my boost clock is only reading vacuum and no boost but it was boosting

I give up.

If you'd read any of the books in the link at the top of the page you'd know where to put the BOV and the feed for the vacuum guage. Hell, if you'd looked at the pictures of any of the turbo Cinqs on here, you'd know where to put the BOV.

Ok no need to be so rude ye
