Occasional Hard Start
Over the past year or so when I went to start my car it starts cranking, acts like it's going to fire for a split second then justs keeps cranking. It will keep cranking with no plan on starting until i kill it. It ALWAYS fires on the very next try, strange. This was happening maybe once a month or so, so I really didn't think much of it.
Now, it is happening much more frequently, as often as every other day (Every 5-10 starts or so). It seems to only happen after the car has been running, I can't recall it happening from a cold start.
Because it only "pops" once then just cranks with no plan of firring, it would tend to make sense that the fuel pump did not get power or the coils stop firring but I haven't started the troubleshooting process yet. Figured I would reach out to the community to save myself some time.
2007 Z06 - Engine is stock from the Intake Manifold down
Major Mods:
Twin 57mm Turbos - 6PSI Boost
Snow Meth Injection
60# Fuel Injectors (Not sure on model - Pre-Existing)
Fuel Pump Booster (Not sure on model - Pre-Existing)
Thanks,

With your mods it could be numerous things. I would listen for the fuel pump when it's not starting. You should hear a slight noise for a few seconds before trying to start it. The fuel pump relay would be something to look at.
