3.0 V6 Starting Problem
My car has a weird problem.
It's a 2003 CF3 3.0 V6, and last night when I wanted to go home the car wouldn't start. The starter motor works, the engine turns over, but there is no start. It just turns over. And over. It did the same the other night, but after a few turns it kicked into life. It also did it over the weekend while I was at family. Car didn't want to start. Left it there overnight and returned midday the following day and it started with the first turn of the key.
Now I have been scratching my head, but eliminated some of the common problems like the Code Immobilizer. The Code sign goes out after a few seconds with the key in. The car runs perfectly fine once it is started. Nothing different. I have a new MAF, so that is also ruled out as the culprit.
Only thing I can think of is that their is a blockage in the fuel system somewhere. I ran out of fuel a while back (while foolishly driving past various stations) and think that some of the inherently dirty bits in the fuel system is stuck in the fuel filter. What do you guys think?
I haven't checked the spark plugs, but seeing that the car runs perfectly fine normally, I doubt it can be it. The crank sensor may also be at fault, but it hasn't died on the move at all.
It did start raining here in SA a week or so ago, so it may be some electric problem too? But what? Oh, and I have a UniChipQ fitted, but it shouldn't interfere with start-ups should it? Only on throttle positions.
Help will be appreciated. Strange that it only seems to happen at night, after quite a long drive (heat).
