The Story:

Car drove 100% last time parked, I go out to drive it about a week later and I am confronted with this start and stall situation. As you can here in the video the car begins to start but then instantly stalls. The car throws a P0345 code only and also some random ABS codes (random because if I clear them and try again it will throw different codes). I have replaced both the battery and the drivers side camshaft position sensor as the code calls for, did not change the condition at all. Any idea what is going on?

The car has been supercharged since 2006 and tuned with the SS box.

 

Is their fuel in the tank?

 

it sounds like fuel pump relay not on.
or it is just like up-rev theft control it is
when you let off the key in the start position
it kills the pump, if you were to leave the key cranking
will it die or keep running??

 

It run if i leave it cranking! So its the relay?

 

Get rid of the grounding kit and make sure all your OEM grounds are tight.

 

sounds like my car when i tried to start it up on the haltech and the maf tune was all fxed up.

Your problem is that ss box for starters. Get rid of that, it is t3h poop. Otherwise I'm zero help.

 

Gonna replace the relay. SS box is fine if you know how to use it and i have had the grounding kit for 6 years

 

You don't have a Phucking Clue what you are Talking About.......

SS Box ( SplitSecond ) is not for the Uneducated....

 

Most piggy backs let the stock ECM start the car then take over. Looks like it's not taking over properly.

 

Swapped relays, still no luck, as soon as i let the key go from start to on it dies, ideas?

 

check for blown fuse for pump

I am sure if you check you get no power to pump when you release the key...
where it is cut ? there are a few places (ignition switch-fuse box-ss box-pump relay)

down load the service manual and it will show you where and how to check
after reading it there too many variables to just shoot in the dark but i am sure
it will find the problem.

good luck..

 

How would it start without a working fuel pump? And why would it throw codes if it was purely a fuel issue? Sounds more like an electrical issue. If really no changes, did it by chance get wet recently? Check for water in the ECU harness and check all the connections to the SS box.

 

Has not seen rain in years, will check the SS box connections tomorrow, i glanced at them the other day and they seemed ok but i will check more closely tomorrow and report back, thanks for the tips guys

 

The issue is not your fuel pump or it wouldn't be firing up. Fuel lines maybe?

When I had a similar issue to that, my TPS needed a reset.

 

im glad you like your ss box. i think they are crap.

ive seen you call names about the ss box before. so why not endulge us all with what makes an ss box so amazing? there's more to this engine than timing and fuel. you yourself have had problems on startup and idle.
if im uneducated i guess that makes you a hypocrit?

 

for a supercharged engine, all you need is timing and fuel. the ss box is just fine for that. really anything past a UTEC is overkill.

 

As soon as you let the key go it is like you turned the car off. It is so weird that this would just happen over night like this....very frustrating. Anyone know how to dianose a bad SS box?

 

i agree in the sense that all you need is fuel and timing really, but compared to osiris... i would definitely want osiris for a daily. the way i look at it, if i have a simple supercharged stock block setup i want the thing to be perectly reliable with magnificent driveability.

 

SS box connections seem fine, any more ideas?

 

Another questions: would using a smaller battery cause an issue like this? I switched out my weak battery for a deka etx18l in the process if diagnosing this trouble.
