The car cranks but will not start. Want to test MAF wiring, but can't find wiring diagram online. Three wires, one red, one green, one red & white. Which one is hot, and which is ground. What is the other? I've had this problem before. It wouldn't start at home so had it towed to shop, but would start at shop so they couldn't diagnose MAF problem at those times. We tuned up, so new plugs, and plug wires. It's getting fuel and spark, so we're looking at the mass air flow sensor as the possible problem. What else could it be?
