Hi, i need some advice for my 05 with 65k.
I changed my decat back to a aftermarket cat as didnt like the drone in 5th.After i done the change over i left it to warm up,after about 10mins the car died and will not attempt to fire up at all.I have done a complete strip of the UIM and checked SSV and intake valve and the all are clean and move freely.
Then next thought was coils,plugs and magnecor 10mm leads,They are all fine with no flooding symptoms but checked all that and deflood steps.Still not firing up?
I have a buzzing from the TB when on AC with key.
Before this the car ran great with regular redlines,mineral oil etc..I am thinking fuel not getting through but need some advice
Thanks in advance.

 

Things you could have touched:

rear 02 sensor, not likely, would have thrown a code
Any wires near the exhaust, need to look for a burned wire
Did it get hot idling?
Gas in the car?
Any error codes?

 

I would think gas too. You have fuel pressure?

it could be the shaft sensor I suppose...but it is unlikely that all 4 coils would die at the same time otherwise

A lot of other issues would still allow it to start and run....maybe poorly but not too many things would cause it to die and not start

 

Thanks both for the responce.

first off i had to drive 120miles home with my decat manifold blown, i got home and done the shut off.Came out and replaced the cat a day later, i put my aftermarket cat back on and warmed her up until smoke poured out from by the UIM then stalled and failed to turn over.The codes are P0443/P2259/P0061/P0172/P0031/P0410/P2096..
I have changed the solenoids,checked my SSV which was well lubed and clean from carbon.So now i am well stumped.I have the TB buzzing as well.

Any help will be great.

THANKS

 

Found the source of the problem today.I had the rear 02 sensor plug totaly burnt out, now i know where all the acrid smoke came from.

I have replaced that but still cant get her to fire up.Any ideas??

 

Check the fuel injection fuses. If I remember correctly the O2 power feed is off the circuit that supplies the injector power.....

 

Thanks for the heads up..

It does sound/feel like there is no fuel coming through so will make my checks on that.

 

@dannobre..
Thanks buddy,

After checking the normal fuses it was a 10amp taillight fuse that was stopping the 8 from firing up.Not what i expected.
