Cause car will do other functions with out ecu powered up. It just won’t run. Most will turn over and act like they are trying to start but won’t if no power to ecu. 4 people found this helpful.

What causes a Honda Civic to have no spark?

This is a pretty simple test. You can find the ignition coil and ignition control module (igniter) test here: How To Test The Igniter, Ignition Coil Accord, Civic, CRV, and Odyssey. Check that the timing belt is not broken. A broken timing belt will cause a no spark no start condition.

What should I do if my Honda Accord has no power?

Ok light should come on just for few seconds and go off. And the voltage drop you are seeing is probably normal with the starter turning over at same time. And you have pulled one of your plugs wires off and checked for spark using and old plug or timing light. 2 people found this helpful.

Can a Honda Accord have an ignition failure?

A very rare type of failure, but it does happen. If this is the condition that you’re experiencing, you will have to wait till your Honda does not start to test the ignition system. This is the only way to test for an intermittent problem.

Why does my Honda Accord LX not start?

I have a 1991 Honda Accord lx that turns over cranks but does not start.. the distributor is not getting spark. The whole dizzy is new,ecu new spark plugs new, wires new main relay new the CEL turns on when the key is on the ON position and it shuts off.. 1 people found this helpful. having same problem here.

Why is there no spark from the distributor?

When a car engine cranks but doesn’t start, then it is highly likely that there is no spark from distributor. When troubleshooting the problem, knowing the exact reason is essential. No Spark From Distributor: Why Does it Happen?

How does the electronic control transmission ( ECT ) work?

The engine ECU monitors coolant temperature and sends a signal to terminal OD1 of the ECT ECU. The ECU prevents the transmission from upshifting into overdrive and lock-up until the coolant has reached a predetermined temperature. This temperature will vary from 122’F to 162’F depending on the transmission and vehicle model.

When was the pattern select switch discontinued in the ECU?

Beginning with the 1990 MR2 and Celica and the 1991 Previa, the pattern select switch was discontinued. In the Celica and Previa systems, several shift patterns are stored in the ECU memory. Utilizing sensory inputs, the ECU selects the appropriate shift pattern and operates the shift solenoids accordingly.

Is there no spark from distributor to spark plugs?

Q: No spark from distributor cap to spark plugs. Car died while driving. Wouldn’t start again. I did basic No start troubleshooting. Tested from the ignition coil to the distributor is good, from the cap itself no power. I replaced the cap, rotor, tfi, distributor itself, and the ignition coil. Same results.

Is the ECT PWR button a turbo boost?

The ECT PWR button is not a turbo boost button. In fact, it doesn’t actually increase the power of your vehicle at all. It’s nothing more than a tow-haul mode button that can be used when pulling a trailer, carrying a heavy load, or when traveling over hilly areas of land like in the mountains.

What should the return voltage be on an ECT sensor?

The return voltage signal should be around 3 to 4 volts, when the engine is cold. This should gradually drop to 2 volts or less as the engine reaches, normal operating temperature. Finally, no change in the return signal, would indicate a faulty (ECT) sensor.

What does the ECT PWR button stand for?

The ECT PWR button stands for Electronically Controlled Transmission Power. If you did the same thing I did, you just said “WTF does that even mean?” Remember what I said earlier Toyota needed a user experience person to help them with the design of their controls? Yeah. You got it.

Where is the ECT PWR button on the Toyota Tacoma?

ECT PWR Button. If you look at the dash of your 3rd Generation Toyota Tacoma, you’ll see an ECT PWR button right under the navigation system and between the Blind Spot Monitor (BSM button) and the Parking Assist Sensors (P button).

What causes no spark at end of spark plug?

There are three specific components inside the distributor that may cause a lack of spark at the end of the spark plug to appear. A broken distributor cap Moisture or condensation inside the distributor cap Broken distributor rotor In order to diagnose the precise cause of the distributor failure,…

How to diagnose the cause of no power?

Pull out the plug from one of the coil packs and see if it is getting power, has a good ground, and has some kind of signal coming from the ECU. If it does, chances are it’s the coil pack itself that’s failed (though both failing at the same time seems unusual).

Why does my spark plug not connect to the distributor?

If you have an older stile distributor cap with female connections the coil to distributor wire will not connect directly to the spark plug tester, but this is not a problem as the wire can be replaced with one of the regular spark plug wires.

Why is my distributor not working on my car?

An issue with the ignition coil results in the vehicle failing to start. Checking distributor cap is paramount when a vehicle stalls suddenly and fails to start again, Check whether the inside or outside has some dirt. It ought to be rust or corrosion-free. Besides, consider checking the working of the rotor and cracks on the distributor cap.

Can a bad spark plug cause an ignition failure?

More likely if your spark plug wires are going bad the motor will run but one or more cylinders will have a miss resulting from a reduction or lack of spark at the plug with the bad wire. There is one exception where a bad wire will cause complete ignition failure and that is the wire between the coil and the distributor.

What causes a no spark or loss of power condition?

Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap. Sometimes, misfiring may not be caused by a total loss of spark but by incorrect sparking or by high-voltage electrical leaks.

Can a jumper wire be attached to a performance distributor?

But, if the ground from the engine to the battery is making a good connection, ignition spark will be none existent. To test for a good ground, a jumper wire can be attached to the distributor by connecting it anywhere on the housing and running it to the negative side of the battery.

What should I do if my HEI distributor is not working?

The first area they suggest you check is to make sure all the wire connections on the cap or solid. If a connection is loose, current cannot travel to where it needs to go. If the connections are good, you next need to make sure the unit is getting a strong 12 volts. Many times, a low-voltage issue can cause a myriad of problems.

What to do if your distributor has no spark?

If, for some reason you have no spark coming from your distributor, the following will help you check and test the installation, connections, and components, of the unit so that you can get your engine running. The first area they suggest you check is to make sure all the wire connections on the cap or solid.

What do I need to troubleshoot a performance distributor?

To do this, you will need a 1/4-inch nut driver and a multi-meter. To test the resistance of the coil, remove the coil cover so you can see the red and yellow wire. Using the multi-meter set on the ohms setting, touch the positive lead to the red wire terminal and the negative lead to the yellow wire terminal.
