Lets see I have a S4 n/a that is now turbocharged with the turbo II factory parts. Emissions removed. Also I am running emanage blue. My problem is that the car won't start up for very long. It starts revs to about 3000 - 3500 then dies everytime. I was thinking that it was a fuel issue or either some wrong setting on the emanage. Anyway, if you guys have any advice or thoughts on the subject it would be a great help.

thanks,

 

At least yours starts! I haven't gotten fuel and spark to my NA Turbo FC yet!

On topic: Some follow up questions -

1. If you step on the gas pedal while it's started can you keep it running?
- if yes, it's probably an idle issue. If it's small you can tune it out with the set screw, but the right answer is to find out why it won't idle that low anymore. In all likelyhood, a vacuum leak.

- if no, then check your fuel pressure to make sure you're able to supply enough fuel, and/or take your battery to the parts store and have it tested.

In a nutshell, every internal combustion engine car requires air, fuel, and spark to run - if it's not running, or not running well, then there's a problem with at least one of the three.

Good luck!

 

jumper the yellow, two prong fuel pump check connector on the passenger side shock tower. Does the car stay alive now?

Have you double checked that your airflow meter is in there tightly?

 

I am assuming that you mean it can only get to 3500rpm before it dies immediately. As in key starts vehicle 1-2 seconds later, it stalls.

that is most likely air flow meter related.....wiring, conection based or afm itself.

i had the same issue and it was that.

argh is prob right with that.

lol is everyone's 6 port turbo running like **** right now? I don't have any other suggestions than the ones already posted, but good luck.

 

Is your AFM hooked up right. Check the connection and make sure its getting a good connection. Bad / not hooked up AFM will cause this to happen.

 

+1 it's the AFM

I had the same issue on my NA

 

If you have one, test the fuel pump resistor / relay. This sounds exactly the problem someone else had recently. The guy ended up replacing his resistor/relay, and the stalling after 3 seconds problem went away.

 

thanks for the help. I will check out the afm today. I don't have anyway of testing the fuel pump resistor / relay but i'm a bit confident that the problem isn't there. I don't have the throttle cable hooked up so I can't give it any gas to see if it will stay on. Is there a way to make the car stop revving to 3k once I turn it on while cold?

 

Assuming your AFM is connected, have you checked the map on the eManage?

Mine's fine...

 

I think the map on the emanage is the problem. It was tuned for a honda, but I dont have the cable to hook it up to my computer yet. If if i bypass the emanage and connect the air flow wires back together. It starts but it keeps reving up for no reason. It will go to 3k and then strat to pull upwards towards 6 for no reason. I just turn the car off at that point. I there a way to defualt the settings to zero on the emanage without the cable. All the jumpers are already set for the rotary config.

Thanks,

 

also the AFM and ecu im using is off the 86 GXL, not a turbo model. Would that make a difference?

 

Well there's your problem! That map is going to be a little different then what you need...

I don't know anything about the eManage though. I prefer standalones that don't suck. I had two experiences with the eManage and those were two experiences too many.

 

if you're using an emanage and you put bigger injectors in, try making a new map, but use the automatic injector correction to adjust for increased injector size and just try to get the thing to start.

 

you should have told us this from the begining.


leave the car alone until you have the ability to tune it.

 

but what would be causing the car to rev for no reason without the emanage? The bigger injectors I take it?

 

personally i'd just stab the fuel pump wire and double check that the pump isn't turning off to make sure it's not a fuel pump relay issue. if it drops voltage to 0 right before it stalls then there is your problem. regardless of what the emanage was mapped for it's still a little too strange that it will start at all and rev to 3500 then stall, which to me points to an issue with the fuel pump turning off due to a faulty AFM, large vacuum leak or faulty wiring to the pump relay/faulty relay.

 

Just came across this from long ago and just wanted to state what the issue was, a very noob mistake at the time. Since I was just trying to test things out I put everything on loosely because I would be taking it right back off. Well behold, I had vacuum leaks and surprisingly it start, but due to the giant leak at the lim it would act like I was nearly wide open throttle. So yea, I fixed the issue then blew up the motor in the drive way trying to hear the bov lol. Brings back memories. Don't know why I brought this back from the dead. Just here at work bored

Cheers!!!
