Ok engine is in looks amazing took days to do but it's pretty lol

Went to start it today and it's back firing and popping or just won't start. It's kinda acting like when the security thing is engaged but the light is not on. I'm not sure if something is wrong or if the tune is out of wack. I got new fic 1000 injectors and used their numbers for the tune. The two grounds on the back of the motor ARE connected and the little one on the side of the block. I've never had a issue starting like this. At one point the plugs were soaked in fuel so pulled about 20% out on the VE table. After that the wideband wasn't in the 10's anymore but still won't start.

 

The block was decked .005 and the heads even less than that. That's not enough to need a change in push rods is it? I have 7.400's in it with stock 6L lifters.

 

Sure the cam is lined up correctly?

 

Yeah. Dot to dot. Even had my wife verify before I torqued the cam gear down

 

You are sure its the dot near the teeth of the gear, right? Not the one in the middle.

Coil packs plugged up? Sure the injector data matches your fuel pressure?

 

Yeah both dots on the teeth. I ask my wife just now. She remembers better than me lol. Coil packs are hooked up. Not sure on injector data. I used the excel file they sent. Put in all the Info for ls1/6/2. Use the red ones acrossed the board due to vacuum referenced.

 

Well, you could try swapping in known-good injectors with accompanying data and go from there. If it works with those you know its a fuel issue.

 

post your tune and ill check out the data.

 

Compression test will tell you if a valve is not closing due to having too long of pushrods. Which is entirely possible having had the block decked and the heads shaved.

Check the basics before you chase your tail too much.

 

I had some problems with the air gap of the crank sensor. My block is a 99(I'm not sure what year yours is), and apparently they were a little closer to the reluctor wheel causing the sensor to hit causing false readings. Just a thought.
