Good day Gurus in the house,

I have been unable to start my car for almost two weeks now. The car cranks but wont start. All the lights in the dashboard are showing, the injector noozles have been serviced, the distributor (Ignition) has been changed and confirmed okay, the BRAINBOX has also been confirmed okay, the security has been disable as well yet it only cranks without starting, the fuel pump was removed and tested okay but will not work when fixed back to the engine and the spark plugs does not spark.


I will appreciate any assistance please.

Have you checked appropriate fuses and relays?

I have checked all the fuses and they are good to go Sir.

It actually stopped while in reversing and I have not been able to start it since then.

What of relays?
It is highly likely that the brainbox is not receiving power or your crank shaft sensor is faulty.

Start by testing the relays, then proceed to crank shaft sensor.

If there is no spark from the plug that clearly indicate that there is issue with the ignition circuit.This is a clear electrical issue.Get a professional electrician that has the wiring diagram of your ignition system to troubleshoot right from the ECU to the ignition coil.

Good one. This is what we have been saying.

GAZZUZZ:
For an engine to run you need the following.

1. A spark
2. Fuel supply
3. Compression
4. All in the right sequence (timing)
5. Air supply (both directions intake and exhaust.)

Use this as a check list and get back to us.


What is missing in your case?

Thank you Sir, only the first two are missing. No spark, no fuel supply.

Thank you Sir. After all the trouble shooting, the Mechanic also concluded that it is an electrical issue. An electrician will check it this morning.

1. Is the ECU in the vehicle the one that came with it or it is a replacement?

2. If it is a replacement, does it have the exact same part number or an upgraded part no?

3. Does this vehicle have an immobilizer?

4. If it has an immobilizer, was it programmed so as to allow a three way handshake between the ignition switch, the brainbox and the immobilizer? Or have you tried to do a bypass.

5. Can you explain the bolded?

6. Where are you located?

7. Can you scan and post codes? If you decide to , please do not use a cheap scanner. I have a personal experience fixing this issue, with a basic scan tool no codes, with a factory scan tool or professional aftermarket scan tool, there were codes that referred to a mismatch between the codes the ECU saw and the codes it expected from the key and the immobilizer unit. I am using ordinary language not the appropriate technical language.

There exists a strong possibility that immobilizer can cut injector pulses so the car never starts even though everything else is in order, except the three way handshake goes the way it was designed to go from the factory.

Thank you Sir.

The ECU is the one that came with it from the factory.

It has an immobilizer and a bypass has been attempted without positive result (The immobilizer was removed for the bypass).

An electrician has been contacted from Ladipo for the scan because Mazda OBD1 scanner is scarce within Lagos Island.

Progress report?
