I own a VL SL RB30E and I am currently having a few issues with my project car that I would like to get sorted as it is due to be on the road shortly. The car is a bit slow to crank over initial, I am starting with a jump pack on as the battery is shot from sitting around to long. Once the car reaches operating temp (1/2 on the gauge) If I turn it off, it will not start. It will crank VERY slowly and sometimes just clicking like the battery is flat, and it only does this when hot/warm(I was thinking possibly starter? but I don't understand why this would only be a problem when hot). If anyone could help I would appreciate it greatly! I have replaced a few things and I have a couple of ideas on what it may be they are: Replaced CAS and rewired plug, so I can rule that out. Replaced Coolant Temp Sensor so thats out too. Fuel is a bit old, it has been sitting for 6-9 months or so. There is only 1/8th left in the tanks o I plan on topping it up with premium and some octane booster to fix this, possibly replace fuel filter too. As I mentioned earlier, starter motor, im not sure why this is only a problem when hot through. AFM as I have heard of this causing similar problems to this. Any other ideas guys? and which would most likely be the problem?
