Still having problems starting with the Senator (3.0 injection).
Usually starts immediately from cold-but when warm and left for a while-takes up to 5 seconds of churning for it to start -when warm/hot and left for a few mins-it starts immediately. It's now started to do it when cold.
Have changed coolant sensor, ecu, MAF, petrol pump, filter and removed the petrol pressure damper.
Did think I had fixed it once when it wouldn't start in the local Aldis' Hit the pump with my jack handle and it started immediately hot or cold. I suspected the pump, put a new one on and it was perfect for about a month-then it went back to it's old ways.
Next think I am going to try is running the car from a petrol can, i.e. disconnecting the pipe from the tank and extending it to put into a petrol jack. This will hopefully see whether or not I've got a problem with the pick up in the tank or the tank itself. The tank was resealed before i got it.
Will keep informed.
