Im having an issue with the car intermittently not wanting to crank after it gets warm. It cranks cold everytime . Once its warm its hit or miss. I've had a reputable tuner working on the car and he's not able to figure out whats going on. Claims the fuel system could be vapor locking or the pump not priming. He's also worked on the hot start but the issue is still present.
Car has ZL1 fuel pump with 1000cc SEP injectors, and aftermarket LSA Fuel Rails .
I can drive the car around, cut it off. Sometimes it cranks back up right away .. sometimes i have to sit there for about 10-15 mins then the car will crank back up. It has never not cranked back up after waiting 10-15 mins. Seems like after it gets under 200 degress it will crank back up. Operating temps are around 215 degrees Terrence d - 11 Camaro - LSA - Boltons - pump gas - cammed - ddtech - New Motor 14.hptnormal drive 6.hpl
Anyhelp? I have plenty of logs of normal driving and the current tune is attached.
