Today my radiator went as I was driving along the highway. When the radiator went the car shutoff straight away. Is this a safety thing that R33's have or is there something more wrong with the car? I did a search but I didn't find anything which is why I think it may be something else wrong.

I just put a whole lot of water in the radiator and tried to start still no luck. I also noticed it all just ran out from the bottom of the radiator.

An undamaged engine will start and run without a drop of water in the cooling system for a prescribed, short amount of time. Your engine has been damaged by overheating, assuming it was running fine before all of this happened.

How long did you run the engine after you noticed the first signs of steam coming out? Tell me you got it towed off the highway rather than running it dry?

So I just thought if try the car this morning and it did start but it doesn't sound at all healthy. I only ran it for a few seconds then shut it off. It making a really lounge ticking noise like its dropped a cylinder of something.

Yeh I should have. Oh well I'll put a new radiator in and see how it goes.

A new radiator wont fix the motor, sounds like a blown head gasket at the very least-

You can do a compression test to determine the condition of the engine

Get a new radiator and fill it up with fresh liquid.

My peugeot wouldnt turn on without anything in the radiator, it was a safety feature. Perhaps 33s have the same gig.

That being said, im not game to turn on my 33 without coolant...

Dude you just told everyone you own a Peugeot? Not cool man...

    • I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.
    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
