Car cranks but will not start

Hi,

If you are referring to the exhaust manifold, that is because it is likely dumping raw fuel into the exhaust and the catalytic converter is plugged.

Here is what I want you to try. First, let's get the spark plug wires in the correct place. See pics 1 and 2 below. Once we are sure they are correct, then I want you to remove the pre-catalytic converter O2 sensor. See pic 3.

I have a feeling the converter is plugged and causing all the problems. By removing the O2 sensor, you allow more air to exit the engine. Because of its size, the engine won't run perfectly, but it should make a big enough difference to let us know if the converter is plugged.

Try this and let me know. Also, moving the spark plug wires to the wrong cylinders is causing unburned fuel to enter the exhaust. That is likely why it is red hot and has likely damaged the catalytic converter (plugged it).

Let me know what you find.

Hi,

I see the crack in the manifold. That should be replaced. However, the idea that you see black smoke usually indicates too much fuel. Have you checked fuel pressure? Also, what is the condition of the spark plugs?

Is it possible for you to record it cranking so I can hear what it's doing?

Let me know.

Joe

Hi,

The new spark plugs won't hurt anything. As far as fuel pressure, if it is too high, that can cause a problem. Also, I wanted to hear what it sounds like cranking because it will help me get a better feel of what is happening. Plus, I should be able to tell if it is a timing issue.

So, have you confirmed the fuel pressure is within the manufacturer's specs? Also, have you checked to make sure the plug wires go to the correct cylinders for timing purposes?

Let me know.

Hi,

First, here is a link that gives a general overview of testing/how to check fuel pressure:

Here are the directions specific to your vehicle for testing pressure. The specifications are included in the directions. Try this and let me know what you find or if you have other questions.

Inspection
1. Relieve fuel pressure.

2. Remove the 12 mm banjo bolt from the fuel filter while holding the fuel filter with another wrench. Attach the special tools.
3. Start the engine. Measure the fuel pressure with the engine idling and the vacuum hose of the fuel pressure regulator disconnected from the fuel pressure regulator and pinched. If the engine will not start, turn the ignition switch ON (II), wait for two seconds, turn it off, then back on again and read the fuel pressure.

Pressure should be: except B16A2 engine:
260 - 310 kPa (2.7 - 3.2 kg/Sq.cm, 38 - 46 psi)

B16A2 engine: 270 - 320 kPa (2.8 - 3.3 kg/Sq.cm, 40 - 47 psi)

4. Reconnect vacuum hose to the fuel pressure regulator.

Pressure should be: except B16A2 engine:
200-250 kPa (2.0 - 2.5 kg/Sq.cm, 28 - 36 psi)

B16A2 engine: 210 - 260 kPa (2.1 - 2.6 kg/Sq.cm, 30 - 37 psi)

If the fuel pressure is not as specified, first check the fuel pump. If the fuel pump is OK, check the following:
- If the fuel pressure is higher than specified, inspect for:
- Pinched or clogged fuel return hose or line.
- Faulty fuel pressure regulator.
- If the fuel pressure is lower than specified, inspect for:
- Clogged fuel filter.
- Faulty fuel pressure regulator.
- Fuel line leakage.

_________________________________

You will need a fuel pressure gauge to do this. Most parts stores will lend one to you. Also, did this problem start all at once? The engine is cranking really fast. If we find the fuel pressure is good, we may need to engine compression.

Also, after trying to start it, pull a couple of spark plugs, and see if they are wet.

It is possible the distributor isn't properly installed. That certainly would cause this issue.

Here are the directions for "replacing" it. It explains how to remove and install. Follow these directions and see if it helps.

The attached pics correlate with the directions.

REPLACEMENT
Removal:

1. Disconnect the connector from the distributor.
2. Disconnect the ignition wires from the distributor ignition (DI) cap.

Pic 1

3. Remove the mounting bolts from the distributor, then remove the distributor from the cylinder head.

Installation:

NOTE: Before you install the distributor, bring the No.1 piston to compression stroke TDC.

1. Coat a new O-ring with engine oil, then install it.
2. Slip the distributor into position.

NOTE: The lug on the end of the distributor and its mating grooves in the camshaft end are both offset to eliminate the possibility of installing the distributor 180° out of time.

3. Install the mounting bolts, and tighten them lightly.

4. Connect the ignition wires to the distributor ignition (DI) cap as shown.
5. Connect the connector to the distributor.
6. Set the ignition timing.
7. After setting the ignition timing, tighten the mounting bolts.

Hi,

You are very welcome. I'm glad to hear you got it fixed.

Take care of yourself and feel free to come back anytime in the future if you have questions. You're always welcome here.
