Cranks but will not start

Welcome to 2CarPros.

First, where does the smoke come from and what color is it? Also, here is a link that discusses the most common causes of a crank / no start condition. See if there is anything there that helps.

The color of the smoke, if it is coming from the exhaust, will tell me a lot. If it is white smoke, that tells me there is a good chance that coolant is getting into the combustion chamber. Most likely the result of a bad head gasket. If the smoke is black, then the engine is getting too much fuel and flooding.

Will the car start if you hold the gas to the floor?

Let me know. Also, it sounds like it is cranking really fast. Did the car ever run correctly since the engine work was done?

Take care,

Welcome back:

If the smoke is black, that tells me too much gas is getting into the engine. That can be the result of a faulty fuel pressure regulator, leaking injectors, no spark at plugs and then you get it and so on. With that, I suggest starting by checking the fuel pressure. If it is good, I want you to pay attention to fuel pressure drop off. What the means is how quickly the pressure drops to 0psi when the key is off. If it drops too fast, injectors are leaking.

After that, I want you to confirm you are getting a good hot blue snapping spark to the plugs.

If both of them, I need you to get a live data scanner. You will check what the engine coolant temperature sensor is telling the computer the temp is. If it tells the computer it is extremely cold, the computer will compensate by making the fuel mixture very rich so the engine will run in those conditions.

Here are some links that will guide you. First, here is a link that shows in general how to test fuel pump pressure as well as the fuel pressure regulator.

Here are the directions specific to your vehicle. The attached picture correlates with these directions. Also, the specs are included in the directions.

COMPONENT TESTS AND GENERAL DIAGNOSTICS
- When reconnecting fuel line, always use new clamps.
- Make sure that clamp screw does not contact adjacent parts.
- Use a torque driver to tighten clamps.
- Use Pressure Gauge to check fuel pressure.
- Do not perform fuel pressure check with system operating. Fuel pressure gauge may indicate false readings.

1. Release fuel pressure to zero.
2. Disconnect fuel tube joint in fuel line and set fuel pressure check adapter (J44321).

See Picture 1

3. Install pressure gauge to the fuel pressure check adapter as shown in the figure.
4. Start engine and check for fuel leakage.
5. Read the indication of fuel pressure gauge.

At idling:
With vacuum hose connected Approximately 235 kPa (2.4 kg/sq.cm, 34 psi)

With vacuum hose disconnected Approximately 294 kPa (3.0 kg/sq.cm, 43 psi)

If results are unsatisfactory, perform Fuel Pressure Regulator Check.
