Customer Question

I'll be honest, I've been less than enthused with the last few responses I received. They just weren't at all helpful.
In this case I just need to know if what I'm being told is accurate or if it's "smoke", and maybe a little guidance afterwards.
1995 Toyota Corolla 1.6L engine. Just died and then wouldn't start. Checked distributor, fuel pump, ECU. We get spark. We have fuel. Starts and then immediately dies (had been working fine before all this). Now we're being told that the security system is shutting the car off, and that we need to disable it (or replace it?).
1. Is this an accurate possible diagnosis (I'm skeptical)?
2. If so, any instructions on how to do this (searched but can't find anything online)?

Hello. Welcome to Just Answer. Please allow me to assist you. I apologize if your previous responses were not up to your standards. I will do my best to assist you. Right now I am at my work, but when I get off at 7 pm east coast time I will be very glad to help you out. Would this be acceptable to you?
Customer: replied 3 months ago.

That's fine.

Expert:  Toyota Service replied 3 months ago.
Excellent. In the meantime, please tell me if you still have spark and fuel when it shuts down, and, does it have the Toyota security system ?
Expert:  Toyota Service replied 3 months ago.
The Toyota security will not disable fuel. Only the starter is addressed when the system is active.
Customer: replied 3 months ago.

The symptoms remain the same, We restart it and it starts and then immediately dies. Not sure how I can tell if there is an anti-theft system. I read something about an anti-theft ECU (which I assume is different from the main ECU behind the console).

I've been told so many different things that I'm beginning to doubt everything. I believe there is gas and spark.

The Toyota system would have a flat black box under the driver seat.
Expert:  Toyota Service replied 3 months ago.
The Toyota system will have a flat black box under the driver front seat. We will also need a 12 volt D.C. test light or D.C. voltmeter for a few tests.
Expert:  Toyota Service replied 3 months ago.

Ok. Please advise what (if any) lights illuminate on the instrument panel when the engine shuts off.

Customer: replied 3 months ago.

I found some kind of flat black security device under the drivers side dash called a Clifford Arrow II. It has a rectangular connector with 2 rows of wires connecting to it. I will look under the seat.

Update: I don't see anything under the seat except a black wire and a 2 or 4 pin connector.

I have both a test light and a voltmeter.

Expert:  Toyota Service replied 3 months ago.

Ok. The Clifford Arrow is an aftermarket type of security system. When it is armed, the power to the starter is prevented.

Ok. Please advise what (if any) lights illuminate on the instrument panel when the engine shuts off.

Customer: replied 3 months ago.

The starter seems to work just fine. After the engine shuts off, the check engine, oil and battery lights are on. I think they are on when the key is just in the On position.

Expert:  Toyota Service replied 3 months ago.

The very first thing we need to check is the easiest, but is the most common... the tube from the air filter box to the intake manifold. Are there any cracks or rips in the tube?

Expert:  Toyota Service replied 3 months ago.

ALso, under the hood, there is a white label. On the engine section, please advise if you have a 4A-FE or a 7A-FE engine. A 95 corolla could have either engine installed

Customer: replied 3 months ago.

It's good. It's now dark and just started raining. Could you possibly list the next several things to check?

Expert:  Toyota Service replied 3 months ago.

You need to locate the diagnostic connector under the hood. Open it and look under the lid for a label. Find the following sockets: E1 and Te1

Expert:  Toyota Service replied 3 months ago.

With a paper clip, insert each end of the clip into those terminals. one end into E1 and the other end into Te1. Turn the key on and advise what the check engine light is doing.

Customer: replied 3 months ago.

Engine code 14. I believe that this is saying that the ECU is not reading the ignition signal.

Expert:  Toyota Service replied 3 months ago.
I have received your update. I will research this and get back to you after work. Thanks.
Customer: replied 3 months ago.

And just to recap, we've replaced the distributor and fuel pump. We have spark and fuel. Car starts. It just immediately dies.

Expert:  Toyota Service replied 3 months ago.

Loss of the Ignition signal to the igniter from the distributor or loss of the ignition signal from the igniter to the computer is the most likely cause. It is possible you have a bad replacement distributor, it is possible that you have a bad igniter. Igniter failures, however, are very rare. If this vehicle was in my shop, the very first thing I would be doing is some power checks. Let's check something if the weather is ok...locate the igniter unit, and then locate the Black with an orange stripe wire that is in the igniter wire connector. First, test the battery voltage across the battery terminals and record that value. Then plug your voltmeter red lead to this wire and ground the black lead. Set the meter to 20 volts DC. Start the car and observe the meter. See if your voltage fluctuates, or is less than battery voltage.

I think it would be wise for me to rep[eat my original question here:

Country: United States
Make: Toyota
Model: Corolla
Year: 1995
Engine: 1.6L

Already Tried:
As we said, changed distributor, cap, rotor, fuel pump, fuel filter and ECU. Car starts and then immediately dies. We get spark, and there is fuel.

Expert:  Toyota Service replied 3 months ago.

I understand your question. I do not believe the security system is the issue. I do believe that the igniter may be the issue, or, your replacement distributor is faulty. The above test looks to see if we are losing B+ power to the igniter. For whatever reason, we are losing the signal to the computer form the igniter. This only comes form one of four things. No power to the igniter, the igniter is bad, the distributor is bad or the ECU is bad.
