Car wont start, no spark and no fuel

[mossimo500]

So yesterday I was driving and the car shut off. I got the car towed back to my house. It didn't throw a CEL. I'm not getting any spark and I don't think the injectors are firing when I try to start the car. I pulled the CAS off and turned it by hand and I had spark and could hear the injectors working. The check engine light and the boost gauge come on when I turn the ignition to the ON position so I think the ECU is still good. The coils and PT were replaced. I checked the timing and it is lined up perfectly still. Any ideas or test I can do?

Is the engine turning over?

Did the intake cam snap in half?

that info is needed, and if you turn your CAS and get fuel then the ECM is "fine" So if you dont have fuel/spark while cranking but do while the CAS in turning by hand, you need to verify that there isnt a intermitten short in the CAS sensor/wiring causing it to work while you were holding it. As for the comment on the cam being broken (however unlikely) just check for movement while the CAS is out (for piece of mind)

I know it isn't common to see a cam break in half in the engine, but I've seen a few.

When i was at Jaguar we had an old XJ come in barely running and shaking. After many hours of head scratching it was found to be a single tooth missing off of the tonewheel. the car thought it had two number one cylinders! After that not much suprises me,

 

[mossimo500]

Yes the engine is turning over, just not starting. The intake cam is not broken in half.

Then how about the
CAS wiring, and how are you testing fuel? injector noise, noid light, fuel return?

You weren't getting spark when you had it towed home, and now you have a new PT and coils, and now you do have spark, correct? Make sure the CAS isn't reversed.

 

[mossimo500]

The CAS wiring looks ok but will check the voltage when I find my multimeter. There is fuel coming out of the fuel return when cranking, so I think the fuel pump is fine. How do you test the injectors?

Still have no spark

I used to keep half of an olds 3.8 camshaft on my desk as a paperweight. The woman drove it in on three cylinders.

with a noid light, but in a pinch an average led light will work.

Is there spark when you turn the CAS manually?

yes and injectors work then also

 

[adidas_coin]

Are you basing the injectors working on the return line? Cause that wont tell you.

 

[Colt4G63 also]

Well then clearly the CAS doesn't turn when it's in the engine. Right?

 

[adidas_coin]

just to clarify: you get spark only when you turn the CAS?

 

[Colt4G63 also]

That sounds like what he's saying. How's that broken cam looking for the perp now? I say the cam's looking awfully guilty.

ya. It wont start.

Yes

No, I can hear them and see the fuel when I hand turn the CAS

he said it wasnt but we need to know if the motor was turned with the CAS off and if the cam was seen turning. if not then then Colt4G63 is the winner,

Aww, man! Now I feel like the bringer of doom. I don't want to win that way. Hopefully it's just a loose wire on the CAS.

i hope we figure this out soon, i have an trans in an XC90 to do tomorrow morning.

 

[Colt4G63 also]

Me too, I have to put the cylinder head back on a TT in the morning.

Is that an Audi head? I saw in your profile that you have your own shop....that means that head is customer pay!!! Sweet!!!
