New turbo setup, no start

[dabbdaddy]

Ok soo I f***ed up somewhere again and could really use some help

Swapped new turbo setup and added a afpr. After everything car turns on but runs like ass. Can't idle without throttle . Fouling 2 plugs almost every startup .
My afpr reads 43 when off (primed with ecmlink) when idle it's at 39ish . Isn't that too high for idle ?
I've done a BLT and fixed the ones I could find from not tightening couplers enough but same problem

Edit: went from 14b to small 16g running same tune, doubt the tune is the problem tho
Engine mods :
750 fic injectors
255 pump
Fuel lab afpr
Fp manifold, small16g , Megan o2housing.

Any input would be great thanks

I believe fuel pressure should be at 43.5 at idle.

That's with the vac line off No? Which is the same as priming with dsmlink with car off if I'm not mistaken . I can't set the pressure with the car on because it won' stay on at all unless I give it throttle

I would retrace your steps and check everything you touched or temporarily removed. I am sure your missing something and just haven't realized it.

Double check to make sure the MAF is plugged in properly.

I just put a AFPR on my Auto car and a 255 pump. I ran 50 psi and just tonite turned it down to 44. It is something else not the pressure although playing with pressures will lead you in the direction if you cant see it on Link.
Could be your injector settings. I do MAFT tuning too and it will run like ass if the injector size isnt real close. Love Link!!

Check your coolant temp sensor, see what its reading for temp. Also check your voltage when running with a voltmeter.

If you changed the turbo out I bet the maf isn’t plugged back in. Lol

 

[EJ'sEclipse]

Do you have a wideband? If so what are the readings?

 

[dabbdaddy]

Lol my maf is definitely plugged in correctly.

Do you have a wideband? If so what are the readings?

I have to give throttle to keep it alive , at 1k rpm I'm at 16-17 . So running pretty lean

I literally bought a new one this morning after another failed start but havnt tried since new one put in

Vacuum leak. I just did Intercooler piping with a friend for my GST recently and it was doing the same thing at idle. Turned out it was the IAT flange for speed density that my friend and I didn’t plug. Imagine how bad it was sucking in air from nearly a 1” hole

Im going to have to borrow one of my buddy's boost leak tester mine doesn' hold that much pressure .
But I've triple checked all my couplers and all hoses that I removed during turbo swap I changed out with silicone hoses and zip/clamped them all down

 

[EJ'sEclipse]

Check your bov line, and any lines that supply a boost/vacuum source from the manifold area and the wastegate, just to be sure

 

[dabbdaddy]

just rechecked all the lines and they are all tied and tight. going to have to wait for my buddy to bring me his boost leak tester to look for additional leaks . i uploaded a log of like 1min worth of me trying to get my car started maybe that can show my problem

 

[Spideydsm99]

Wastegate line?

 

[kmetiuk]

Exhaust leak.

If you are running MAF and your showing lean and giviing it throttle and you know you have no boost leaks then I'd starting looking at the exhaust.

 

[dabbdaddy]

Wastegate line?

Zip tied, connected to mbc

Are you sure that the fpr isnt leaking internally. sucking fuel in through the vacuum line? What codes do you have?

 

[dabbdaddy]

Current codes are for egr and rear o2 sensor .
Il pull the vacuum line and check for fuel but highly doubt it , brand new fuel lab afpr from extremepsi

Have you made sure that your plug wires are in the right order? Have you verified that your getting spark on all four? Are you pulling the plugs to see which ones are fouled? are they on a common coil? Are you replacing the wet plugs? Sometimes the plugs are junk after they foul!

Yes I'm getting spark on all 4 . Everytime I foul I replace. I have another 8 pack of bpr6es to replace as I go along
The plugs that keep fouling are #2 and #3
Correct firing order

And this thing ran fine before? have you done a compression test? have you verified the mechanical timing?

Man it was running fine , steady idle , nice afr all the way to redline. Turbo started going , had alot of shaft play so I got a new set up and now this.
I havnt been able to do another boost leak test but il get to it tomorrw to completely rule out a boost leak.

You sure you didnt leave a rag or something stuck in the intake. Sounds like the car is way too rich and not getting enough air.
