Afternoon all, Having a couple problems with my engine (RB30) in the VL. It seems to start fine, run quite well for anywhere up to 30 minutes (including driving and as 30 mins is as long as I have been bothered to go for). It's been sitting in my garage for 6 months as I had another project car. The problem is however, when the ignition is turned, the fuel pump is loud and bumpy (for lack of a better word) and when the car is running, it has a tendency (not all the time) to 1. Die completely and not start after idle. 2. Give off signs of it going to die, like failing for a second, then coming back, but if you touch the gas it immediately after it starts to die it will rev then return to a normal idle.. And then will repeat this process unroll it dies completely. Can any one give me a hand, I seem to believe it may be the fuel pump and that it's failing to supply the engine with fuel. Thanks, Mitch.

Check your wiring to the fuel pump - make sure there isn't a loose wire. I once had a loose wire - car would cut out if I hit a bump on the road, had to reach under and wiggle the fuel pump wire before it'd prime/start again. If wiring is all in check - i'd replace the pump and see how you go.

Yeah, I had the same problem with my other VL but it sorted itself out over time. - I had a quick look, the wiring is all plugged in okay. But yeah, I think it's time to replace it. Thanks.

Fuel pump it was.
