No SPARK ?!?!?!?!

[cketcc]

i have a 2003 chevy silverado 6.6

had to change my injectors the other day got them done plus batteries we old so i replaced them too !!

NOW !!! when I go to start it !!! It wont SPARK at all !!! Does any one know why this would be happening ? Or even a site I can go to to try to find out why ??
Thanks

Uh.. It shouldn't have had spark before the injectors were replaced... If it's not starting you probably don't have it primed.. Prime the filter head.

Troll!

yea tried that.. got it primed went to turn it over it tries to turn over and NOTHING !!!

everything ran great !!! untill after i changed the injectors.. very frustrating Im getting no codes

Have you checked fuses? Do you have access to efi live so you can determine if you are getting adequate fuel psi?

 

[cketcc]

so this is were we are at now !!! the truck started and stayed running 30 seconds then died !! then if you wait a few mins it will do that again !! by chance do you have any suggestions

We need data from the truck.. Not you. What's rail pressure doing? Where did the injectors come from?

Guys, it looks like he has an LB7, doesn't seem to know a whole lot and just "attempted" to swap injectors...

$10 says he's "making oil"

When you changed injectors did you change the spark plugs? There are 2 per cylinder like a hemi, they are located in the valley behind and above turbo to the left of the DEF tank... Could also be the spark control box, they are very hard to find on a diesel so bear with me... Located under the left motor mount, in the aft oil pan on the starboard side of the cp3 inside the transmission valve body upside down and inverted.

Check the driver side distributer to make sure it's getting adequate fuel pressure.:thumb:

oh boy, let the games begin. :roflmao:

try putting some gas in it, that should do the trick

Prob a bad fuel pump in the tank

It's the piston return springs. Not enough rebound to make the spark.

When I had spark issues I checked and redundantly replaced everything...

Then I dug deeper and my worst fears were confirmed...
Yup
It was the Flux Capacitor...
That, and I was low on plutonium, I wasn't making 1.21 giggawatts anymore and the flux capacitor wasn't able to control the injectors duty cycle and as it turns out, a duramax won't fire with anything less than the 1.21 giggawatts anyways

So a quick trip to my local extreme duty electrical supply store and the nearby uranium/plutonium distribution hub and I was ret ta go yo
