Greetings. I recently did a timing chain on my 08 Buick LaCrosse 3.8 series 3. While I did the timing I also replaced the ignition camshaft sensor and the crankshaft sensor. I put everything back together and started it and it ran great. Drove it around the block, shut it off. Drove it about 10 miles, listened to the timing chain via a stethoscope and it sounded great, then shut it off. Drove it about 30 miles, shut it off. Went outside to go to work and it wouldn’t start. Replaced the battery, replaced the fuel pump relay, pressurized the fuel system still nothing. Checked the fuel pressure from the pump and the pump is working fine. The car is turning over and cranking but just won’t pop and start. Any thoughts?

Other things that are less than 2 years old on it are: spark plugs, spark plug wire, water pump, alternator, ignition control module, serpentine belt, serpentine belt tensioner.
