Replaced crankshaft sensor, car still will not start

Welcome to 2CarPros.

First, are you certain the sensor was bad? Have you checked fuel pressure? Try this little trick. See if it starts for a couple seconds if you use starting fluid. If it does, then it is a fuel related issue. If not, then we have to check for spark.

Here are a few links that explain how to check for spark and fuel to the engine. I'm adding them in case you don't feel comfortable using starting fluid.

Here are the specific directions for testing fuel pressure. The attached pic correlates with these directions,

_____________________________

FUEL PRESSURE CHECK

CAUTION: Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.

NOTE:
- Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pressure cannot be completely released because Z50 models do not have fuel return system.
- Use Fuel Pressure Gauge Kit (J-44321) to check fuel pressure.

1. Release fuel pressure to zero. Refer to "FUEL PRESSURE RELEASE".

2. Install the inline fuel quick disconnected fitting between fuel damper and fuel injector tube.
3. Connect the fuel pressure test gauge (quick connector adapter hose) to the inline fuel quick disconnected fitting.
4. Turn ignition switch ON and check for fuel leakage.
5. Start engine and check for fuel leakage.
6. Read the indication of fuel pressure gauge.

At idling: Approximately 350 kPa (3.57 kg/sq.cm, 51 psi)

7. If result is unsatisfactory, go to next step.
8. Check the following.
- Fuel hoses and fuel tubes for clogging
- Fuel filter for clogging
- Fuel pump
- Fuel pressure regulator for clogging
If OK, replace fuel pressure regulator.
If NG, repair or replace.

Now, if you have proper fuel pressure and spark to the plugs, confirm there is power to the fuel injectors. Here is a quick link that explains how to test for an injector pulse:

Lets start with these things. Let me know the results. Also, let me know if when cranking the engine, if it sounds normal or seems to be spinning faster than normal.

Take care and I will watch for your reply.
