This is the issue:
Have the car 8 months-
The car has not started on about 10 occasions and that dreaded red injection light stays on in the dash.
The first 3 occasions the engine sputtered and coughed and then died. And yes the red light on the dash stayed on. After trying a few times the car coughed and sputtered again and the fired up as normal.
On the last 7 occasions there is no sputtering or coughing, the engine turns over as normal but does not fire and the red light is on in the dash. If I leave it for an hour or 2, turn on the ignition and if the redlight on the dash stays out, the car starts perfectly.
I have noticed that the issue starts after a long journey and is left sitting overnight or for a number of hours(i.e. when the engine is cold).
Otherwise the engine is perfect. I have brought the car to an AR dealer on 2 occasions and they have just said it was a loose connection, my gut feel is they have done nothing, tried the car a few times and it has started.
Any help would be much appreciated. Thanks.
1st: Welcome to the *amazing* world of Alfa's.
Your story mirrors my own in many ways.
I have several thread here relating to stating issues, wierd flywheel issues, temp issues ECU's etc............
TODAY, March 3rd, my mechanic tells me all the above are been caused by
A bad EARTH connection/lead going onto the engine block, this is after 4 days of testing, swapping sensors, ecu's, diagnostic tools etc.....
My faith in EOBD & s/w is now shattered....... as a good mate of mine always says GO BACK TO BASICs before spending lots of dosh on fancy diagnostics.
So as a guide to help you try:
1. Cleaning up batttery connections
2. Check all Earth wires around the engine bay.
3. If the issue is still there then go to an Alfa garage to get the car tested on a diagnostic machine.
Sensors or things that may/will casue this non-starting issue when *warm* are:
a. crank sensor
b. flywheel/rpm sensor
c. cam sensor
e. bad connections
f. all the above
As a matter of interest have to tried to start the car *on the run* or down a hill when the red light is on. I found that by doing this car car would eventually start
... maybe a bad thing for the CAT in the long term.
