Hey guys just wanted to see if any of you Greddy TT guys have trouble starting up your car sometimes after you have driven it for awhile. Sometimes I try to start my car and it wont start, it takes a couple of times for me to turn the ignition on before it starts. I was wondering if it could be the bigger injectors or if something is not right. I need to know if any of you guys have this issue or is it just me. Thanks in advance.

 

Sounds like a issue you should look into. I've never had that problem.

Did it just start doing that or has it always since the install?

ever since the install.

 

No problems on mine and going on15k + miles

 

i have that same problem. its because of the injectors. i know that some of the people w/ 1000 injectors have that problem really bad.

 

So you are saying it is normal? How do I get rid of it? Is there a way where you can flash the ecu or the emanage to compensate for it?

 

Who would that be??

 

Sorry, it's not due to the injectors. Myself and the other Greddy TT in my area have had no drivablity issues at all with the kit.

I've run 850's in my cars before with no starting issues.

There are various issues that could cause this. I doubt it's a Emanage or ECU problem, of course nothing is impossible but very unlikely.

Check to see it you can smell any fuel after the car has been running. You might have a pinched upper o-ring in the fuel rail allowing a small amount of air into the system causing a prolonged cranking cycle.

I would pull the fuel rail and check the o-rings then reseat them very carefully. It's not hard at all to do.

Also pull the plugs while your there (with the intake manifold off) and clean them. With how rich we run these things the combustion chamber builds up carbon fast.

Quick question, once it starts does it run smooth or does it stumble any? It should not run rough at all.
HTH,

my rpm bounces from 600-700. It is smooth until I drive it hard or for a prolong period of time it starts to get rough and you can feel it shake when the rpm rises. I am running real rich on my setup as well. I havent got it tuned to lean it out. So far it is still sitting at 9.8 on my AF. I bought the NGK iridium one-step colder plugs which I havent installed yet. Hopefully it might make a difference with the plugs in.

 

when my ignition timing harness was installed, my tuner added a little fuel at idle-that smoothed it out very much...the difficulty starting issue, i have had as well, it may turn over for 2 seconds tops and then start, any longer than that is NOT normal

 

After my install, it was noticeably harder to start the engine. To alleviate it a bit (doesn't always work), I'd keep my key in the on position to trigger the fuel pump (not good if you have the ignition harness hooked up), wait 3 seconds, then turn her over. Seems to work well . . .

Since its a lot colder than it was in June, I have yet to have a hard start situation. Could the weather have influenced this?

that would be you, heheh

 

Tim..you might check for an air leak in the system.

"An air leak in the presence of a mass flow sensor will rob the sensor of some of its signal, creating a lean condition on start-up"

Maximum Boost by Corky Bell

Look downstream from the throttle for disconnected hoses, big cracks in the hoses, tubes dislodged, etc.

 

if none of the above options work, have you cam sensor checked. there is a recall on the early VIN cars that relate to a malfunctioning Cam sensor that will cause hard/long start conditions.

 

Im not really sure but couldnt this be the problem, 9.8 A/F is extremely rich, does your car bog down when boosting?
My friend was having the same problem in his rsx. He had trouble starting it up and when boosting in higher rpm's it would start bogging down, it seem like your having the same problem, if thats the case get it tuned your too rich.

 

I dont really feel the car bog down when I am at boost. I am running real rich though and killing my gas mileage. I think this could be the problem as well.

 

Maybe after I change my spark plugs to one-step colder, it might help a little. How hard is it to change plugs? I have it already and just waiting for my friend to install it for me.

 

get it tuned at a proffesional tuning shop. And get it checked out by a reputable mechaninc, someone with a good reputation and following. Word of mouth has to be good.

There's a lot of mechanics that could leave you worse off than before.

 

Looks like mine is being caused by a check valve left in from my previous fuel system. Thanks KShep and phunk for making me look beyond the injectors!

 

Glad you were able to isolate the source of the problem t32gzz.
