Hard to crank after sct tune
I've had my sct tuner for about a month now and although it has made my car quicker, i think it's also made it hard to start sometimes. It doesn't happen often (maybe once or twice a week) and it mostly does it when I have done a bit of driving or on warmer days. Sometimes the car will start and just shut off, when I try to crank it immediately after, it just turns and turns but won't crank. Whenever I turn the key back and wait for 20-30 seconds it starts. I also have a leaky intake manifold which is leaking coolant but I don't think that would have anything to do with the cranking problem. Does anyone know what could be causing this? Any help would be greatly appreciated!
