First startup today, need help with some issues

[Stripes]

I've got an s14 sr20 in an s13. I put a few mods on there and am running witht he stock ecu.Fidanza flywheelMegan turbo manifoldMegan pulleysSSQV BOVKoyoMegan ElbowGreddy LS FMICSARD 550cc'sGreddy knock off intake plenum

anyway, I started it up and at first it seemed like i had to give a good bit of gas to keep it running. Sounds really deep and sputters like it's got a serious cam. Boost is reading fine, can't figure out how to hook up my oil pressure gauge correctly so i'm not sure about that but i changed out the oil before i started it. It smokes a lot too, I'm running nothing after the turbo elbow but it still shouldn't smoke so bad. I dunno if this has to do with timing (which i'm not sure how to get it adjusted exactly right) or what. Any help?

What color is the smoke?

[Stripes]

gray

Too much fuel... Did you mod the ECU in any way for the injectors?

[duffman1278]

Check for boost leaks and vacuum leaks. Whats you're fuel pressure at?

[Stripes]

ECU is bone stock, no safc or enthalpy or anything. Leaks? I think I need to get my timing right before I can start checking for that, but no I do not believe I have any seeing how all of my hoses are hooked up correctly. Also, I have no gauge to visually show me my fuel pressure so I don't know what it's at.A friend of mine said it's pretty normal to have a lot of exhaust after startup.

Could be a boost leak. Did it just start doing this or have you not had it running? Could also be the maf.

[Stripes]

I just started it up for the first time, so no it hasn't been running. I thought about the MAF also but I need to get my timing set right before I can test that because I'll just rev it and if it bounces at 3k then I'll know it's the MAF

[crashcourse]

My s14 did the exact same thing. Do you have a NA ecu or WC? This may sound weird but I have heard the Kouki to Zeinki MAF sensors are different. I ended up putting a power fc on mine and z32 maf and went.Now I am back on the stock ecu with Z32 maf and a safc still runs decent. It was never right all stock for some reason and I wonder if I had a zeinki for a kouki maf.....

Why check your timing is it a swap you just installed , or is it one you just rebuilt? Unless they swapped your cam angle timing should be ok from japan . I have gotten a swap where they did pull the cam angle but it wouldnt run at all, untill I found the issue.

[Stripes]

WC ecu. The maf is for my motor because they all came from the same car. Also I'm going D-Jetro Power FC here soon so I won't need a MAF anyway.

The reason I think I need to mess with my timing is because my CAS bolts were loose when the motor came in, so there is no telling whether or not it is positioned right. Second reason is just by listening to the motor I can tell the timing is off unless someone put 272 cams in there or something.

[zeause]

Checking the timing is always a good idea. SRs are known to come out of timing frequently. Running 550s without a tune of any kind or a piggy back could be a lot of your problem too im sure. I bought my car already swapped and the guy that i bought it from payed to have it installed and it never ran right. It had a sohc ka maf on it, which is ok for a s13 sr, but not a s14. I had to get a z32 and a safc and it ran fine until my oil pump went out. Now its in pieces in my garage.

[crashcourse]

I think the s14 has an oil issue .. That makes 3 now that I have heard of oiling issues. I did a swap for a guy and 4 days later he spun a bearing. He put royal purple in it and it ran great for the few days he had it.Then mine went out at 6000 in 5th gear. I wonder if the VTC and the sr together just love the oil and spin bearings easier than the s13. It sounds to be, so keep them oiled boys lol.

[Stripes]

It has the right MAF and plenty of oil.Here is what it's doing now.

After startup it wants to die unless I give it gas. If I don't give it enough gas to get around 1.3k it will die. When I try to rev it to above 3k it will have late response, will only jump for a second and when it does it sounds like it's cutting out and after firing. If I don't give it some gas after revving it will die.

Some things I have researched and I think it may be are:

TPS not set right due to my 550cc injectorsMAF plug could be bad. I tested this by running it unplugged but it is hard to tell because it's running so bad anyway.Boost/ Vacuum leak. I want to make that tester thing I saw on here and see if I can find any leaks.

Thats all I can think of. Does anyone know if it would run really bad if the knock sensor wasn't hooked up?

[crashcourse]

I know the knock sensor is there to retard timing under detonation. If it does not read the sensor hmm not sure . I know the rom tuners eliminate the knock signal. Are you running 550cc with no ability to adjust. Put your stock injectors back in it.

[Stripes]

So I tinkered with a few things and it is running better now but still not right.It idles now, but at around 2k. It will idle for about 30 seconds or so and then it dies out, like the fuel pump quits or something. Also, if I hit the accelerator it will die. It's acting like the fuel isn't putting out when air comes in.

What we've thought of so far is....The tps reads a voltage based on the position of the throttle body. Right? So what I'm thinking is this voltage reading gets sent to the ecu, then to the fuel pump, ultimately telling the fuel pump to give it the right amount of fuel for the amount of air that is coming in. So if this is right, then the only thing I can think of right now is that for some reason the fuel pump is not getting the correct voltage reading to pump more fuel, which is why when I give it gas it dies out.Now, I cut the pink and black wire coming from my fuel pump relay and grounded it with a switch because for some reason the fuel pump was not getting power with the wire routing the way it was. I don't think this could be the problem but I figured I'd let you guys know

[zeause]

Im pretty sure the pump pushes the same amount all the time. the fuel pressure regulator controls the pressure in the fuel rail and the injectors control how much fuel sprays in the cylinder. Have you pulled your plugs and looked at them?
