triple checked pushrod length? if the exhaust valves are hung open slightly unburnt fuel would pour into the exhaust no matter how you adjust the injectors.

did you check PTV when the motor was going together? could have dinged a few exhaust valves on first startup?? just spitballing.

 

If cam sensor is wrong it wont effect fueling and will have cam code

Fueling is tune related...your build is simple so any tuner can get ya running if they have a clue

 

You say 58 PSI of fuel pressure. Is the fuel pressure referenced?

Are you running SD? If so what MAP sensor.

If not, what MAF are you running? There are different values for some MAF sensors.

As Atomic said earlier I would start with good known injectors like stock injectors. Once you know that variable is correct you can move on to the next thing.

How long are you able to let it run? If you are cranking and floor the pedal it will lower the fuel while cranking. Sort of like an old carb engine.

 

Yes it is a 3 bolt cam with 1x gear. Wiring for cam sensor is extended and outer 2 wires switched per direction for the LS2 timing cover with sensor.

Stock length pushrods from comp. I did clay a couple pistons and rotate the engine over with rockers intact and it had tons of clearance with the stock LS9 cam.

Yes 58psi at idle and its an aeromotive 13301 vrfpr. Im running a gm 2bar map part#12615136 and speed density. I have to lightly throttle it til it warms up a bit and then it will idle but gas smoking extremely bad. A few times ive had to hold it to the floor to fire it.

 

Above 80% throttle (factory setting in the tune) during cranking is flood clear mode, which disables the injectors not just lowers them.

What does your MAP sensor read with the key turned to ON but the engine off? 2bar OS installed, right?

 

Your fuel pressure should be 58 with the vacuum reference unhooked.

I would put a stock MAP sensor in it with the stock values and do not go in to boost at all. This is just to figure it out, then go back to the 2 bar.

If you are running a MAF out of a van and you have a tune for a truck that will also be an issue.

I would check the fuel trims for each bank when it idles. Don't just check one side.

 

You get fed up enough and want to sell the thing get ahold of me.. seriously..lol
But hope for your sake you figure it out, check the fpr function/leaks at all? just tossing out ideas..

 

Im about ready for someone else to own it!!!

 

I almost feel stupid for even having to admit the problem i found that has been causing the rich flooding issue. Have no idea why it has'nt crossed my mind to look at my vrfpr til one of my friend's called friday morning and commented on it. Some of you guy's on this post have mentioned it but hasnt crossed my mind of it leaking....The regulator diaphragm has went bad inside and is pushing fuel through the vaccum port and right into my vaccum block and then straight into the intake thus causing my flooding issue. I have no earthly idea why i have not let that cross my mind as to why fuel was getting everywhere that it shouldnt. Truck is running now and good to go.

Thank you all for all the idea's and help through this. Bunch of knowledge on this site.
