Hey all
Ok, at the moment my car is stranded on the side of the road and I can't get back to it until the end of the week (and no Towy would tow it on a sunday!) but I just want to brainstorm for some ideas...
So, exactly one week ago I drove about 40 mins to get to a wedding ceremony, the car ran perfectly the whole trip. I parked it and when I came back after the ceremony about an hour and a half later the car wouldn't start. It would fire and turn over for a second then stop. Fuel? right? So as it was a fair ways from home I got it towed to a nearby mechanic and he was convinced it was the fuel pump... sounded reasonable to me so he went ahead and replaced it. Problem solved.
I drove the car to work and back on 3 occasions with no problems (each time leaving the car for at least 10 hours before restarting). Then, yesterday I drove up the road to a mates house and turned her off for about an hour before restarting... guess what? same problem as before - car starts and runs for a few seconds then dies.
Now all I had with me was my trusty leatherman and a paperclip so I checked:
*for fuel at the rail - seemed to have plenty of flow
*cooling the Crank angle sensor with water - no change
*the spare key, in case of immobiliser issues - no change
*checked fault codes - code 12: no problem
*Operation/condition of fuel pump and Efi relays/fuses - all ok
*Plugs to Ecu/map/airflow/crank ang sens/oil pressure sens/ - all appear ok
*Spark (JUST IN CASE) - all good
Now it seems to either fire and run for a second or just turn over on the starter with nothing at all in complete random orders.
I'm certain its a fuel issue... I can here the pump working and it has flow, although i havent been able to hook up a pressure gauge just yet. Or possibly a dodgy sensor like Crank angle or coolant temp preventing it from starting???
I have never worked on commodores so I'm not 100% on all the ins and outs of the electrics so if anyone has anyone got any ideas Id really appreciate it
Thanks in advance
