Will not start

Hi and thanks for using 2CarPros.com.

If you have a good spark at the plugs, either it is not getting fuel, something has happened with the timing, or the engine compression is too low.

Do me a favor, if you have not checked fuel pressure, make sure it is within the manufacturer's specs.

Condition: engine idling, regulator vacuum hose disconnected
Pressure should be: 260 - 310 kPa (2.7 - 3.2 kg/Sq.cm; 38 - 46 psi)

Condition: engine idling, regulator vacuum hose connected
Pressure should be: 200 - 250 kPa (2.0 - 2.5 kg/Sq.cm; 28 - 36 psi)

Note: both conditions are with the engine running. You should find pressure a bit higher then the non regulated pressure listed.

Here is a link which shows in general how to check it:

Next, we need to know if the fuel injectors are working. Here is a link which shows how to check:

If the fuel pressure is good and the injectors are working, then it is time to check engine compression to determine if a belt has broken or if it is just too low. Here is a link which shows how that is done:

I have one last thought. See if the engine will start for a couple seconds using starting fluid. If it does, then the timing and compression are okay and we need to focus on why it is not getting fuel.

Let me know what you find or if you have other questions.

Take care,
Joe

There are many. Weak or bad pump, plugged fuel filter, injector not actuating, bad regulator allowing all fuel to return to the tank, fuse, relay, PCM. The list goes on.

Have you actually checked fuel pump pressure?

Let me know.
