I recently bolted up a plenum throttle body and CAI to my 03 GT. It's Accufab's 70mm TB plenum combo and K&N CAI from American muscle.

After installing I've checked all the connections and the car will not start. Starter engages and it turns over but it will not fire. I'm completely at a loss at this point and was hoping someone had some insight or had the same experience.

Thanks

try to play with the pedal... not wot tho... maybe idle just needs adjusted

or you ****ed something up

Tried that because I thought maybe it needed some adjustment but it still won't start. When I put the key in and turn on I don't hear any fuel flow or anything like that. Could my anti-theft system kicked in somehow. I'm stumped

Check and make sure you have the main vacuum and IAC lines hooked up in the front and the evap vacuum in the rear hooked up.

I know you said you checked all the connections but make sure the maf is connected.Also maybe somebody bumped into your car and tripped the inertia switch, or maybe your fuel pump happened to die.If you cant here the pump run check the inertia and then your fuel pump relay,then the pump itself.

The car will start with the TPS and MAF unplugged. It might start with the IAC unplugged depending on where the throttle set screw is at. It will not start if one of those vacuum lines is disconnected.

Not trying to argue,but i disagree with you, my maf was unplugged once and my car definately would not start also with the vacuum lines disconnected ive done that before and with the evap line unplugged it sounds like you have a huge cam and with the iacline of the car will rev really high when it first starts than stall.I dont think thats what he is experiencing.

No I have driven my car after forgetting to plug the maf back in. The computer defults to learned memory and uses the TPS and ECT to decide how much fuel. Unplugging the IAC could stall the car if the TB blade is not set open enough, if the hose is disconnected the car will not start. The evap line ricer cam trick does work if pulled while running but if pulled before starting especially after changine out the tb/plenum can cause the car not to start.

Did you disconnect the battery while doing all this? If not, do so (disconnect the battery), and start checking fuses...

Isn't there a reset button in the trunk by the drivers tail light? I think its a fuel pump reset???
