Hard Start Help
Hey guys my name is Josh and I'm new to this whole forum thing.
I have a 2007 base model with the auto, and I had the trans rebuilt recently, i got kevlar clutches and i have a 3200/3400 stall converter, longtubes, no cats and a tune on it. the car has 102k miles, and the problem i'm having now is that when i try to start it, the car will crank for 6-10 seconds then it will start up like it usually does. i was thinking the fuel pressure regulator, but there's no CEL's and i took it to my performance shop and they're thrown for a loop as well. I'd prefer to avoid the dealer as it's about $120 an hour, and if it's any sort of fuel issue that i have to get to the tank, it'll be a hefty repair.
Any help or advice on this would be really helpful guys thanks!

It can be so many things---
Do you have a cam ??
Please list all your mods--
Sounds like the hard start began after the trans rebuild and the 3400 stall---Is that correct
? There should be no reason that after a trans and converter change you would begin to experience a hard start----
More info would help to diagnose----I immediately would suspect a clogged fuel filter
---With a stall converter there is less load on the engine when started but not usually enough to alter the starting----May be a coincidence --How long was the battery dis connected ? If too long the computer will revert back to a failsafe start up fueling---
I would drive it foe awhile with multiple starts and see if it finally learns out--If not then follow up with your mods and if there has been any tuning

Full mods are vararam ram air, lg motorsports longtubes, full exhaust 2 1/2 with no cats, trans rebuild with the kevlar clutches, 3200/3400 stall multidisk converter and a performance tune. The hard start issue didnt begin until i got the car back from the transmission shop that did the work, and if it was a clogged fuel filter wouldnt that make it cut out regularly or not start at all? Once the car starts i have no problems with it its only the initial start up. I put my foot on the brake and press the start button and the starter will turn the engine over for about 6-10 seconds (it varies) then the engine will start. I used to be able to put it in accessory mode and leave my foot on the brake and it would start after leaving it that way for about 3 seconds, but it doesnt do that anymore.
