    Default Need help with no start issue

    I have a 2011 Escalade that I just did a dod/vvt delete with a mild cam, new lifters, springs, long tubes and ory and rebuilt the transmission. I removed the battery while I worked on it. took about 3 weeks. Got everything back together and loaded my base tune and it wont start. It wont even turn over. kinda like it has a dead battery. The battery is fully charged. I go to turn the key and all the dash lights turn off. can someone look through my tune and see if I missed something?

    So I missed the pin on the gear selector when I installed the valvebody. I got it to start but it dies after a few seconds. Can anyone help me please?

    Got it to stay running at idle with little hunting. But its running extremely lean. Pegged my aem eugo wideband at 18.5. Is there a rafig or similar precess like on the old ls1 pcms

    Found a few exhaust leaks. At the exhaust collector and there a 90* turn and another lap joint and clamp. The wideband is after the 90* bend. Does anyone know of a fix that doesn't involve a welder?
    Also. My efans are not coming on. Was watching the map and clicked on data and coolant temp was at 212*F.

    Can anyone help please? I'm running around in circles trying to get this to idle right. Wo2 was saying it is extremely lean. Added fueling to the idle area now the map has shifted showing around 80kpa at idle.bg/cylinder was around .45-.55 and now it's getting .9 and only runs for a few seconds

    I started over with a copy of the stock tune file. followed the auto vve guide and the idle guide. Still cannot get it to stay idling. Im attaching my current tune and a log of several attempts to start it. the last attempt ended with the exhaust backfiring.
