First tune record - help a newbie

[Taz]

Hello gmh308,

I believe post #28 is a quote from a thread I linked - don't think we're that far yet (engine starting that is). I have a similar swap booked in later this year, and would be very interested in learning more about the "bypass calibration for this relay test" - you mentioned.

Thanks for the help ....

Regards,
Taz

Thanks Guys! GMH308, the file is in post #20 of this thread for PCM, TCM is post 26. Thanks so much. Sounds like I need to trickle some current into my black and yellow harness wire....or not if I have this software by pass...

Engine cranking but no start. No light on injector noid but has spark.

Try this engine tune...........

Good chance it will fix your problem if the start relay check is getting in the way.

Will try it. you guys Rock!!!

OK … you set G1220 (Starter relay type) to “not used” … and G1219 (Starter relay diagnostic) remains “enabled”.

Anything else …… to help me understand the changes required to omit wiring a relay circuit …

Just updated to build 133 today … don’t recall seeing these parameters before …

Still no start on my end. In diagnostics it reads

ECM P0615 -FPHXNCS
I think this is the starter relay control circuit.

Not sure if its relevant but my original starter was bad and not cranking. New one has been installed and it started cranking right after.
Thanks for your efforts.

Disabled G1219 and now trouble code is gone but still no start.

Again, thanks everyone for all your help. I will keep at it.

B9903 says "disable vats patch" applied.

should I get some trickle power to the Yellow with blk ign wire?

Hey guys. My tuner would like a scan (he likes 7.5) of me trying to start the car so he can see what is going on with the injectors. Can someone walk me through this?

Thanks so much. Your patience appreciated.

Did you set VATS Type to "2" in G1210?

I just checked and the cal you sent had it set to "1". (this is covered elsewhere in this post and also the VATS sticky and in the VATS OS patch help).

It will not start with VATS type set to "1".

G1220 is the option I set in the cal I posted for you so it is correct at "not used". Have never seen G1219 have any effect either way.

The crank/start relay feed will have some trickle current regardless of any other settings.
