Help my sr will not start

[sr12det]

Just like to say hi and that this is a great club. I have a sr swap in my 84 200sx, she is mint and a sexy girl with many rare aftermarket parts, body kit ex.. (And lighter then the compatition 1520 kg) My motor all of a sudden doesn't want to start. I have fuel, spark and the motor is turning over! WTF eh???? So by the process of elimination i think its a maf sensor. If anyone in the Guelph area can help by dropping there maf 4 like 20 min there is some cash ill toss, and beers too. Or what are my options???

It doesn't want to start, or it doesn't stay on? If it doesn't want to stay on, check the mafs. If it doesn't want to start, check the timing if you're getting fuel and spark.

Does it not start when hot or when cold. Or does it not start at all. If you have fuel, spark, timming ok, then it could be your temperature sender. The one to the ecu, not the one to the gauge.

When I first got my sr swapped, my car would not start when it's hot. After a little cruise, if it's turned off, it won't start till it's cooled down. Turned out to be the temperature sender on mine.
