Takes 2-3 times for car to start after adjusting ...

[2 Lane]

So I've adjusted some parameters and the car takes 2-3 try's to fire up now,where it would fire up instantly on the default settings any ideas?

I can't give you an answer on that one. Those adjustments aren't related to startup in any way.
I assume you have the 5.7 chip?

It's a 5.6 actually.... So I put it back on the default settings to see if it would get rid of the hard start issue and that did not help. Guess I need to check my crank sensor?

 

[EricM]

Maybe, but I would make sure the fuel pump is coming on and you see fuel pressure. If that's good, then I've seen misadjusted cam sensors cause that. Also, sometimes low voltage at the injectors can cause it. Which injectors do you have?

Well got 38 lbs at idle 43 with line off. Msd 50's for injectors. Guess I will have to do a voltage test and check the cam sensor with my Casper tool thanks Eric.

Well Eric I know it's been awhile but this no start problem ended up being a faulty fuel pump relay. Or just a plain ol bad connection. But I did replace the relay and my fuel pump is louder than ever lol. So I need some advise, I am really wanting to lean on my car towards the end of this season. My current combo is a 5.6 pump gas chip, scanmaster 2.1,stock longblock and cam ,63 mm Garrett precision hybrid .63 exh.CAS V4 slic, power plate,stock Maf,cold air intake w/K&N,adj.fuel reg. hot wired Walbro but I really would like to put some 116 octane in it and turn up the boost to 24 26 lbs to try to dip into the 11's.
Wondering if I can safely tune this with my 5.6 chip and scanmaster trying to keep the timing low and turn the boost up. Any recommendations?

is your maf showing a full 255 when you go wot?
how does your O2 look when doing wot?high 7s to low 8s?
are you getting any knock retard on the timing on the wot blasts?

if these things look good and it were my car I'd put the octane to her and crank up the boost.
