Default Help!!!

So last night we got everything buttoned up on the car and tested, I have fuel, spark, etc. we go to start the car an it just cranks, and slowly. I haven't hooked the laptop up yet but would a slow cranking speed cause a no start problem?

A few guys have said their MSD ingnitioned car would not start unless they had a fully charged battery. Is your battery full power?

My first few tries was a bust...had to spin the motor pretty fast. Now with it running, not bad at all.

I would put a tune in NOW with a laptop....do not use the pills unless you have NO choice.

It was a yellow top I had laying around, I have it on a 2 amp charge now so hopefully tomorrow it'll be fully charged It has a brand new starter and crank sensor aswell, and it's a bone stock 5.3 so I hope it's just the battery

You need to post his name and address so we can all make sure he doesn't do that to anyone else. What a piece of crap!!!!!!!
