2006 Buick Lacrosse CXL 3.8 will crank and run fine for a few minutes then will cut off and not crank again unless it sits for a long period of time. Have replaced crank sensor and cam sensor. Have replaced ICM as well. Still having the same problem.
Cannot figure out what the problem is. Have replaced ICM, crank sensor and cam sensor. Have checked wires for open and resistance and no problem there. No codes are being set either.
