It started for about 4 seconds then shut off. It acts like it's trying to turn over but won't checked fuses look good, checked relays they look good, fuel is good. I went and checked for spark and had no spark at all.

I have seen the MAF sensor go out can cause this issue, you can unplug it to see if the spark comes back, I have also seen the crankshaft sensor go out and do the same thing, no spark. Here is a guide on no spark problems to go over as well.

Here is the location of the MAF and the crankshaft sensor so you can check it out:

You can use a scanner to check the RPM when cranking and if it is at 0, I would replace the sensor. Check out the images (below). Please let us know what happens.

Yep, bummer, the engine has no compression. It sounds like the timing chain as let go. This means the valves can be bent, can you confirm the car's mileage?

You can confirm the failure by doing a compression test.
