Sprint RE installed. Worked for a few days now wont start.
 

So I installed my sprint RE on my s5 swap. Worked really well untuned for a couple days but then it just stopped working. Here is the setup so far.

Fresh rebuild using Atkins master kit (w/ cryo apex, side, corners)
BNR stage 4 turbo rebuild
1000cc primary, 1600cc secondaries
KGP fuel rails
AEM fuel pressure reg
Walboro 255 fuel pump
Bridgeport
Exhaust port
Haltech Sprint RE ECU
OMP delete
Stock coils (for now)

So im getting spark. Getting 50psi on fuel. Made sure injectors are firing. Timing is set to "top dead center." Cant get the thing to start. During the crank the AFR says rich between 10-12 then goes lean past 17. Im thinking it might be a timing issue, but i may be wrong. Any ideas?

does it want to start ? or just cranks ?

It wants to. It will get past the threshold and start for a second or two then die. But that's only every once in a while

need more info, batt voltage, coolant temps, outside temps, etc......

Figured it out. One or both of the primary injectors were clogged

That'll do it
