Does not start, wants to, but just will not. Replaced starter, battery, spark plugs, ignition coil and module. What does the fuel Sol fuse do? There is not one on my car.

Good afternoon, are you able to check the fuel pressure? There is a access port on the fuel rail for this test. If you do not have a tester, you can rent one from AutoZone or Advanced Auto.
Lets test the pressure to see if you have a failed pump.

Okay, thanks. The spec is 62-66 lbs.

You are at the lower end of the pressure.

Try spraying some ether or brake kleen into the air filter and see if it starts and stalls.

It sounds like you have a crankshaft angle sensor that is out. Here is a guide to help you see what you are in for when doing the job:

Please let us know what you find. We are interested to see what it is.
