Any help is much apperciated im new to tuning so got alot to learn

What i have is a 5.3 with a standalone harness engine only... I disabled VATS, Set PNDL switch to none and tried to start no spark...

Here is where im not sure i havent yet changed the tune to speed density 2 bar and im missing a few sensors

ECT
MAF and IAT
Both o2 sensors
oil pressure
oil level

Not sure if any of these can cause a no start or im missing a step in the tuning

 

Might want to check and see if your gettin voltage to your sensors.

Your ECT missing could cause some problems along with the IAT.
When i did my cam swap i had a wire come loose and found out when i opened my scanner. It wouldnt fire off till i hooked that wire up.

 

What wire was loose? I'm gona try a ect and maf later...

The pcm is from a v6 bravada I changed the firing order and displacement don't know if I'm missing something there

 

I assume you loaded a V8 calibration to replace the V8 calibration.

I did not I just modified the v6 tune I planned on getting a truck pcm but that's what lkq gave me said its the same pcm

 

The V6 is set up for 1 coil and runs a HVS and NOT a 24X crank trigger. You will need a V8 calibration.
What type of software are you using?

 

HP tuners

 

I can build you a file that will work and not cost you any additional credits. We get $140 for this.

This is not something you can copy and paste to get it up and running. My startup tune will match your VCM ID, OS ID, and the VIN that are stored in the PCM.

I will need a copy of your tune to make the above mentioned match my tune

 

I'll keep in mind cal

 

If you would like we could clone your PCM and make up a second PCM for you
We get $200 for a 2nd PCM cloned and tuned. Tom is in Rockford and works in Crystal Lake. You could save a few buck on shipping if you met up with him. He might even make you a deal on reprogramming your PCM onsite.
