s4 na 1/2 bridge wont start please help
 

Well everything checks out, but she wont start. she tries, and if I pour alittle gas into the intake she runs. by herself though she just tries to start but not actually start.
new plugs except the trailings are my old but cleaned up leadings.
tps checks out at 9.22*
fresh engine just rebuilt her
does anyone have a clue as to what this could be? Im stumped.
please and thank you.

need more info on your setup

check your egi fuse in the main fuse box by the battery, and main relayfuse. if good disconnect then crank over let engine sit for a day. then hook back up and start her. its def flooded. its new motor so you have to build compresion. also check all vacum hoses. that there are no leaks.

post pics of your motor.

@ beefhole its a s4 everything, ported intake and engine
and some emissions delete.
@ jo rx7 alright ill try that. :)
thanks guys

could be a bad injector, could be bad injector wiring, could be a bad airflow meter, could be a vacuum leak, could be ignition timing improperly set, could be low compression, could be bad grounds, could be a faulty ecu, could be low fuel pressure, could be many many more things.

the fact that it runs when you pour gas into pushes me to think you have a bad injector, poorly or non installed main engine harness ground loop or bad injector clips, neither are uncommon.

thanks karack thats what I was thinking because ecu is good, no vacume leaks, everything checks out. im trying the flood clear then wait tell tomoro. but if she doesnt start I think im just gonna suck it up and get the uim off again. any tips for testing the injectors and harness.
thanks ill post pics tomoro guys

the best method of testing the fuel system integrity is the injection test in the FSM, get some wire and tie the injectors to the rail and use a spare crank angle sensor and spin the gear with the ignition turned on. this will tell you if the injectors are firing or not. if only one is firing then you have an issue with the one that is stagnant. if neither are functioning then i would assume the ground terminal on the engine harness is the issue OR the fuel pump has died during it's hibernation, jumper the yellow test connector at the RF strut tower and you should hear the hissing of the fuel through the lines, if not then something is up with the pump or pump circuits.

the pump checked out fine today. the only thing that is up in the air is weather its the injectors or wires or something i cant think of. thanks a big one man I would never have thought of using a spare cas to test that. good thinking.

more info on the car but i did report it and redo the whole rebuild with new parts.

I didn't read much of the other thread, is this doable on (are you using) the stock ECU?

yea for now

I am unsure if the stock ECU is fit to run a bridge. Perhaps some others can chime in???

You need way more fuel. Put some 550CC injectors in there and it might start. Probably happier on 720s. Takes about 2.5ms of injector time on 720s at 40PSI to just idle my bridgeported 6 port.

their not as big as you guys expect and I just did a little street port on the pri ports, then some bowl work with some small 1/2bridges. I got a buddy who got his to run ok until he went standalone so I think it should run because Iv always qestioned them. which is all im looking for at this point, but just until next month then rtek, big injectors, custom header and a shortend and reworked s4 intake mani or if all this fuel injection gets the best of me im just going carb.
but now that aaron cake says it might not guys got me worried lol ^^^^^^^^^^^ stating to sound really good to me.

Bridgeports, regardless of their size (unless crazy small to be almost useless) cause major overlap and thus massive exhaust pollution into the intake stroke. You need way more fuel to overcome this.

Don't go carb. Carbureted bridgeports suck in every way possible except at wide open throttle. All the bad press that bridgeports get comes from the carburetor, and not the port.

In order to get the most out of those ports, you'll also need to ditch the stock NA intake. Or at the very least, gut the plenum.

AAaon is right about that comment on carbed bridgeports. Seen many 12a full bridge on holley 650's in my day.. and they are not very daily friendly.

wrong you dont need to up your injector size. your stock fuel system is suppling more than enough fuel for your setup. im still running my stock 460cc in my fully built fullbridge and we tuned it to be as fuel efficent as possible and car still runs rich. look up my build and youll see what im talking about. just check over the basics. grounds conectors etc!

your car will run with all the stock mainifolds and injectors. yes going with a full standalone will make it that much better. but for now its fine. look up my build im still using all my stock mainifolds, im standalone now, but still using stock injectors, and mainifolds. all emissions removed.

thanks guys I haven't had a chance to check her out yet, but I got suspended (long story). so im gonna go ahead and check tomoro. jo rx7 thats awesome, but im still going standalone when I get a chance.
@ aaron you've been my hero in the rx7 world ever since I first read about tina. lol so I dont think im going carb anymore on that note. I am gonna shorten the an s4 intake I have around about 20cm or so then also rearrange the dynamic chamber so the tb is on the other side kinda like a tii intake.

checked out the injectors, and there all working. the only thing I can think of now is timing. any tips for setting that on the cas? I messed with it earlier and got better results, but not running yet.
thanks

advance the CAS one tooth at a time and try for a few seconds, could be a pulley issue being that there is 2 pulley sets for the FC with rather drastically different timing results if you mix them up.

that probably happened. two motors in one room both in pieces at the same time lol.
thanks

So yeah, I've tuned a bridgeport or two in my time...

You have a standalone. He has a stock ECU. Big difference. 460CC primaries are fine with a standalone because you can tune any PW you want at idle. This can't be done with the stock ECU.

Any dyno sheets of your full bridge on stock manifolds? I'm guessing ~220 RWHP.

you're generous than me, i'd have guessed less than 2.
