    so i still cant get it to start. when i plug in my laptop to the aldl connector and look at the data i can connect with the pcm and the sensor data looks as it should be. CTS matches ambient temp, TPS seems to be operating properly. map is a no vaccum but while cranking i can see the map signal pull a small vacuum but not full obviously its barely cranking compared to running rpm. It also back fires a little one out the intake. i added extra fuel thinking it was lean? but seemingly no difference in how it stumbles and tries to start but then wont.

    The fuel table I was playing with is under the BPW Parameters and is labeled Idle VE vs. MAP vs. RPM. Is this even the right spot to be looking or should i be playing with tables under the category listed as Cranking Fuel Parameters? non of them say ve or anything.

    That was last night. ill try puling fuel this morning. maybe thats the right direction? On the original computer the truck ran really rich at idle under a stock bin file but it did run just fine always started.

    ive tried adding fuel and removing fuel and nothing. Is it just me or is the map reading looking funny? starting to think its not my fueling im lost please help
