HELP

OK this is the deal. The 6.0L is all hooked up mounted and everything. You turn the key on and it does everything right, just wont start. wont even turn over. I was reading forums before and ive heard the the fuse/box/PCM is dif on a 4.3L and a 6.0L. Where can I get a wiring diagram so I can go in there manualy and put everything in the right Pin #. Ive seached the internet and nothing. It is a 99 4.3L V6. and the new motor is out of a 2001 2500 HD 6.0L LQ4. Im needing yall bed guys. Please HELP!!

What PCM are you using? Have you disabled the VAT's?

a little off topic, but how many times a week do you change your sig??

Oh, I'm not complaining on the new one!!

haha hey u can thank me for his sigs haha i did one and he liked it but hes done the last two, and they look pretty sweet. look for QUICKSILVER TRUCK CLUB to be a new member soon got something for ya&#39;ll&#33;

I&#39;ve probably got the diagrams you need at home in electronic format if my CD goes back that far. I&#39;ll check for starting diagrams for both models after I get off work. I believe this topic has been addresded before on this forum however. A search might yield the info you need. Another way to get the info would be to subscribe to Alldata on the web. Or perhaps hummertech will see this, he has been very helpful to others on wiring diagrams.
Oh, and if it is not even turning over, disabling VATS in your PCM is not the issue. But you must address the VATS issue to get it to run longer than a couple of seconds.

Ive seached and found some LS1 diagrams, but that doesnt help any. I looked into Alldata, but I was going to see if anyone on here knew or had the diagrams before i though about the subscription. Its not even turning over, so VATS isnt an issue right now. If you can please help me with these 2 diagrams so we can get the Pins changed to the right ones&#33;&#33;&#33; Were almost complete&#33; Thanks man

Sorry about that, I read a little fast and didn&#39;t see it wouldn&#39;t start period. Let me see if I have a diagram.

When I had that problem, I found that the big purple wire wasn&#39;t getting power. bypassed the fuse block&#39;s relay, and "BAM&#33;" The starter lead from your old setup is usually a thick-gauged wire (red or purple) that comes from your old fuse block. You CAN probe with a multimeter to check you voltages to confirm you&#39;re getting power to the necessary points you need power to.

The multimeter is your friend. Check to see if 12v is making it from the ignition to the starter. Isolate the blockage.
