Why won't my vehicle start? It does crank. No codes are shown. No check engine light

You either have a fuel delivery issue, too much or too little air to the intake -- I'd guess too much since we have a cold engine, or an ignition spark issue. There's no guessing to be done. What is missing when the vehicle does not run? If it won't run, checking it should reveal the missing element(s). Your question indicates you have a sense of what you're doing, but you're clearly missing part of the problem. By the way, your check engine light has no relevance if the vehicle does not run. The MAF sensor probably wasn't off concern. You likely still have an air intake concern. I'd focus my attention first on the entire air intake / intake manifold / vacuum system, if I was looking at the car. www.repairpal.com/repair-shops
