Skyline R33 series 1 no start

[SkylineR33Lad]

Thanks Ben. I have put a timing light on it when it is cranking and it is in the middle of the timing marks I think there is six and it's in the middle. Can I pull the injectors out and then pull the cas out and turn the cas to make the injectors spray full just so I can see there spray pattern. I know they are all clicking when activated.

I know this is a big ask. But does anyone live around Sydney north shore and willing to come give me a hand this weekend. Really would be appreciate!

Yes you can

Sweet bro. I'll pull them out again tomorrow and have a look and make sure they are all spraying right.

I think it is worth checking that the cam timing is correct before you go too much further. If that is correct, set the engine to TDC compression on number 1 cylinder and set the CAS so the spark is firing at number 1 plug. If it doesn't fire using Start Using Bastard, I don't think the problem is fuel related.

Okay guys so I pulled the fuel rail off again. And had my Mazda 3 running and stole a vacuum line of that to the fuel reg on the skyline. It turnt the cas and the injectors a clicking and there fuel getting to the rail but I don't think it's getting pass the regulator! Could this be the fault or at I missing something. There's only one vacuum line coming off the fuel reg! I've also got the return line off the fuel rail and there's no fuel coming out the return with the key on. But the pump is loud and I know there's 6 bar of pressure there.

It has already been suggested that you could have the fuel lines around the wrong way on the reg.

So swap them

Hmmmmmm

You do not need to hook the reg up to vacuum for it to work

The vacuum/boost supply changes the pressure to suit what the car is doing. More boost = more fuel pressure. Without the Vac line doing anything you will have what is called base pressure

I think its already been suggested but just in case. Fuel pump line should go to filter then to rail then from regulator to fuel return

Okay guys I really was hoping not to have to post in here again but I need your help again. I am very embarrassed to admit but yes Ben you were right I had the fuel lines around the wrong way! Was spewing when it fire over straight away. But now onto the next problem. I have got it idling fine and sounds really nice but it is in limp mode after I drove it 500 metres up the road. I have checked all vaccum lines and Intercooler lines and they are all on. I did find a small vaccum line behind my glove box that wasn't hooked up to anything so I blocked it with a screw. I've triple checked every single plug and also tried the afm with the second one I have. I've also check for fault codes and I'm get 55 witch means everything is fine Again sorry for the late response guys.

So its not in limp mode then if it has no fault codes.......

So more detail on what it is doing? Not boosting well? Smells really rich? Misfires?

Is it on a standard ECU?

[SkylineR33Lad]

It's in limp mode. Can't rev over 2000 rpm. Idles perfect and you can drive it slowly but just cuts all power when you get to 2000 rpm.

[89CAL]

Reset stock ECU? Sounds like AFM but you said youve changed that.

[inmaniac]

What exactly happens at 2k rpm? Lots of things could be happening here.

Is it only when you start building boost?
