I have a issue with my car starting when it is warm or the car is at a certain temp. I have PTE 880's with other mods etc etc. Then tune is great and we have tried to address the issue but it seems when the car has been driven and has sat for maybe 1-2hrs or it is hot/humid outside the car takes may turnovers to start. Fuel has been added to startup but after today (warm and very humid) it isnt any better. Is this just a injector issue or can it be tuned out?
*Edit* This problem didnt start until I installed the injectors.

 

do you have meth injection? I used to get meth siphoned into my IC pipe after I shut the car off when it was hot and it sat for a few hours. It used to crank for a like 5 seconds then start like crap until the meth burned off. I now have a check valve and problem is solved.

 

No meth, Just basic bolt on's. Dp on exhaust, Perrin intake, PTE 880's, Boost controller, ETS 3.5 kit. This issue just started after I put the FMIC kit on and the injectors. idk whats up with it but its irritating.

 

Bump. Car almost wouldnt start again. As soon as it starts the A/F is really lean. We have tried adding fuel to the start up but nothing seems to help.

 

So I read on another post that if I give it gas on the startup and it starts up fine then it is in the tune. Where in the tune is the issue? We have added fuel to start but got no result. Any ideas?

 

id say the whole problem lies in the injectors... i really dont have a clue why this happens but i heard it alot after bigger injectors are added... fuel pressure solenoid?

 

Yeah I am at a loss. Starts great when its not warm out or the car is not right around the line above C. Pretty irritating.

 

idk man, hope you get it fixed soon!

 

Still have not figured this issue out. It never fails to start and when it is first start up of the day or right after (5-10min) you cut it off its fine. I pulled the plugs again and they look fine and I also swapped the plugs out. Any ideas or is this just how these injectors are?

 

i have the same issue but haven't been too bothered by it until lately with the hot weather..have you checked this thread?

Thanks. I am going to get a road tune this week to see if I can get it worked out. And the same here it was only happening once in awhile when it was cool but now that it is hot its all the time. Ill keep you posted if I get it fixed.

 

What ROM version are you using? Maybe the Scaling is off. Just cause WOT is great doesn't mean the rest is on the money.
If the injectors are scaled to big they won't stay open long enough creating a weak or lack of combustion during initial start up.

I have my injectors scaled at 880 scaled @ 660 i believe.

 

Yeah I am not 100% on the ROM. Hopefully I will get it figured out in a couple days.

 

let us know.

 

Well it seems Kasey fixed her. I havent had another issue with starting today. It doesnt have the sputter issue after starting either. It also idles better. I am not 100% on what was done to fix it because he changed a few things with the timing, fuel and idle. He pretty much did a road tune on it. The real test will be tomorrow after work because it always does it after work lol. Ill post up and let you know.
