Hi everyone. This is my first post (be gentle).
This is an intermittent problem.
Hard to start HOT (after say 20 mins standing), or hard to start COLD first thing in the morning.
My VS Caprice has had the same starting problem symptom for the past 8 months. It is intermittent - every 6 to 8 days. The problem occurs either first thing in the morning after "resting" through the night, or about half an hour after leaving it in a car park (hot).
When hot, the problem occurs, usually half an hour after leaving it in a car park (hot). I hear the fuel pump "wer", making lots of gurgling sounds. The motor turns over OK and then splutters once, and then nothing. Eventually (usually, just after ringing for the NRMA, it starts, usually by the standard "foot flat on the floor before the ignition is on technique"). When it starts it can blow buckets of black smoke for a few seconds then runs as sweet as sweet.
Or, when it does not start from cold in the morning, it just cranks with no indication of life at all. Eventually if my battery is still OK it will start, no reason, no smoke, just sweet as sweet. I think that mostly when HOT, it is flooding, but when COLD, 50% of the time it is from fuel starvation because just before it starts (from COLD) I often hear the fuel pump suddenly prime the fuel rail even though I always hear the fuel pump "wer" when the ignition is switched on before the relays click in control. The other 50% of the time COLD start condition is similar to the HOT condition - obvious flooding with buckets of black smoke for a few seconds then runs as sweet as sweet.
To-date Auto-electricians have replaced plugs, ignition module (twice), fuel pump, computer (swap-out) no effect so they re-installed my original. Coil has been checked. CAS in the dizzy is suspect and also the fuel pressure regulator, but there are varying opinions on this. Apparently the computer codes are of no useful indication.
I would like to be able to monitor the codes myself. If anyone can tell me what I need, I would be very appreciative of the help. I am computer and coms literate.
Other than this starting problem, the engine runs as good as new - very sweet. It has never stopped while running.
As I have mentioned, this problem is intermittent and is driving every one insane - a legion of NRMA people and Auto-electricians are close to suicidal, not to mention yours truly - ready to burn the car before signing in to the asylum. HEEEEEEEELP!!!!!!!!!
