Go back to your stock tune, raise the idle RPM a ~100 RPM, Do a search on RAFIG and RAFPN, that should help with the start up problems you are having...

[knuckles]

i cant even get it to start on the stock tune now.

knucles,

Welcome to the forum.

It should be able to start and run even if it won't run properly.

Are you sure you're still getting plugs and injectors to fire...?

Are RPMs indicated while cranking...?

Are you sure there are no air leaks around the intake manifold (and it's various vacuum ports)...?

Start with your stock tune file, goto table B0101, increase the whole table by 10%.

be for i started with the efi it would start i checked the manifold for leaks and found none. i will try the 10

Put the original tune back in there and see if it starts.

(also, you should be doing cal-only flash and not full flash).

[knuckles]

i will check on that

[knuckles]

i have no clue it is the red arrow that goes down but says curent cal

[joecar]
