Help, Engine Check Light Flashing! Car starts for 5secs then dies

[CMF_Virusash]

Hi all

Im fed up with my second micra, My stupid little SR wont work properly. I have a major problems with it

Well the car starts then dies after 6 secs!!!! The engine check light keeps on flashing continuasly (Sorry about the spelling). This just happened because i was checking the fuses because the back lights wouldnt work. I did some research on "engine Fault codes" on this website and tried to bridge the connections to find out the fault code BUT NOTHING. This car is my secondary and want to get it fixed so i can sell it off! I havent called the RAC or bothered to call a mechanic because the last time this happened my mechanic charge me £40 to change an engine temp sensor! Im new to this electrical stuff and im well steamed up about it!!!!! Hope some one can help!

The engine check light keeps flashing while the key is on the ON position!?!?!?

Btw this car is a 1996 1.3 SR with Nats key fob

hope anyone can help
Thanks in advance all

Can anyone help??!?!?

Try getting the fault code(s) this way.

Take the kick panel off the centre tunnel beside your clutch foot & on the other side. You'll see your computer in the middle.
Unbolt the computer from the car, there'll be enough cable to get it out the passenger side.
Take the top off so you can see the 'diagnostic mode selector' trimpot rather than trying to turn it through the access hole.
Turn the ignition switch on, but do not start the engine.
Turn the pot fully clockwise. Wait at least 2 seconds, then turn pot fully counter clock-wise.
The ECU is now in Diagnostics MODE II
Read the codes flashing from the check engine light. Long flash is first digit, short flash is 2nd digit, see the codes below.
To exit MODE II, turn pot fully clock-wise. Wait at least 2 seconds, then turn the potentiometer fully counter clock-wise, or...
Start engine with the ECU in MODE II to enter MODE II - Heated Oxygen Sensor (O2) Monitor . The ECU is now monitoring the O2 sensor. Warm the engine to normal operating temperature, then run at 2000 rpm for 2 minutes. Check that the check engine light blinks more than 5 times every 10 seconds at 2000 rpm. NOTE: Light indicates signal from sensor to ecu. ON=rich, Off=lean. Blinking light means system is constantly adjusting between lean and rich which is normal. Any other indication would be abnormal and require further investigation. The switched on/off is 'closed loop', while a constant on or off is 'open loop' 11. To exit MODE II - Heated Oxygen Sensor Monitor, turn the potentiometer fully counter clock-wise and stop the engine.

I had a similar problem (though intermittent at first) with my 1996 Micra 1.3 GX. Turned out that it was corrosion to the fuse for the NATS immobiliser (the 10 amp blade fuse in the engine bay fuse box next to the left hand headlamp - in the position shown as INJ on the fuse box cover diagram). A year later, the problem recurred but this time it was corrosion (in our scabby British weather) to the connectors (in the bottom of the fuse box) for that particular fuse. Check that your fuses are all OK first, if they are OK then it may be corrosion underneath the fuse-holder. I got mine fixed by a mobile autoelectrician who replaced the faulty fuse connector with an in-line fuse holder in ca. 30 minutes of labour.

Good luck,

P.S. Incidentally, the autoelectrician also did the same fix on my left-hand headlamp fuse which I'd previously had to solder back in after it had overheated in a Chernobyl-style meltdown (a common Micra fault along with overheating and consequent distortion and poor contact of the connectors to the headlamps themselves).
