Basic Points:
Battery Fully Charge.
No Rain by ECU
Starter Replaced
Basics Work
Fuel Pump works and was replaced 3 month ago.
Fuel goes entirely through fuel rail
New Spark Plugs
Can't test Alternator unless car is already started...
Fuses are good
1/2 Tank of Gas

Problem: Car Doesn't Start?

The are 'cranks' but doesn't turn over.

Solution: Before I start replacing parts like a crankshaft sensor. What might also be a problem with it?

so u get the "chugging" type noise where the pistons are moving but u cant get the car to give u any internal combustion?

1) are u sure the sparks are sparking to ignite the fuel?

2) could be the crankshaft sensor

3)im not sure, thats the first thing that comes to mind, because if it was the starter it wouldnt crank at all. If it was the batt it wouldnt do it either.

good luck man.

O! is the car throwing any codes? if so have that checked out it could help ALOT!

first thing to do is check codes

How do I test to spark plugs to ensure its sparking? I replaced the plugs/coils.

Could it still be the crankshaft sensor even its still a "chugging" noise?

Whats the pedal trick to get the codes?

Thanks

I would bet its the crank sensor.
