So my 9k the other day didnt start. Redid the spark plug gaps to proper spec and fired right up. But upon driving around discovered that I once again had a stutter under full boost (reminiscent of when coolant was leaking into the cylinders) about a week later it wouldnt start again and hasn't started since. Swapped the DI for a known good one, checked the timing (matched the slot on the crank pulley to the raised mark on the block, not the weird symbol) and im not entirely sure what to check with fuel but I primed the fuel pump from the fuse box and it worked. Anybody have some advice on what to check next for a no start??
