Hey all, I have a 6 cyl EF Falcon, that was just repaired after a minor accident.
But now it won't start properly, however it does start every now and then, and I can drive it ok so I ruled out and fuel or ECU or alternator problem since it has worked on the occassions it did start, however I could be wrong!!, I have checked all fuses and relays.
It has a brand new battery as I thought it was the problem....The car's engine cranks, turns over but it won't fire...once in a while it will start though. I honestly don't think it problem is accident related because the accident happend september last year and I have driven it alot since then with out incident, but now soon as I get the money to fix it, it does not start properly and I had to tow it to and from the panel beater, and its due for an inspection to be re-licenced, having it starting it properly is important to pass the inspection.

Could it be the fuel system, ECU, BEM or coil pack???

Does any one have any ideas about it, or simple remedies I may beable to try to fix the problem, or know what is causing the problem?

thank you, Aaron.....:)

isint the bem more to do with interior electronics not mechanical as this is what the ecu or eecv does

apart from the check things like crank angle sensor, coilpack, fowled plugs leads arcing out few thing like that as it doesnt sound like a fuel problem :D

To get the codes, do you put the multimeter on ohms or volts?
, on volts I get 1.34V and no other codes or numbers show up how do you reed the codes on a digital multimeter?

This is what I tried below, and it did not do any thing????


[The Self Test Codes can be read using either a Multimeter, or an LED, and consists of a number of Pulses outputted on the Engine STO Pin, and the Vehicle Diagnostic connector (The STO Out Pin is the 5th Pin from the left, on the upper row).
These codes can be deciphered by using the format,
1/2 Second On Time for Each Digit,
2 Seconds Off Time Between Digits,
4 Seconds Off Time Between Codes,
6 Seconds Off Time Before and After the 1/2 Second separator pulse.

To Perform a Key On/Engine Off (KOEO) Self Test,
1. With the Ignition Switch Off, Connect the Engine STI Input to ground, (The STI Input is the First pin from the left, upper row, connect this to the Pin directly below it)
2. Connect a LED, Multimeter, Lamp, or Buzzer to the STO Pin, and ground. (The STO Pin is the 5th Pin from the Left, on the upper Row.)
3. Turn the Ignition Switch to On, But DO NOT START the Engine
4. Observe the Codes.
These codes will be displayed in the following sequence,
1. On Demand Codes - Hard Faults
2. Separator Code - Numeral 10
3. Memory Codes - Intermittent Faults]
