LeSabre doesn't start

94 Buick LeSabre

- New Spark Plugs and Wires
- New Crankshaft and Camshaft Sensors
- Replaced Ignition Module and Coils with used working ones
- Tried Computer from another LeSabre (same number) Switched PROM
- Fuel pressure OK
- Compression OK on all cylinders
- Don't see any vacuum leeks
- I see spark and Injectors spraying

But doesn't start! It turns but no signs of starting.

Any help would be appreciated.
