Hi folks. Because i love self punishment ive not long finished returning a sierra 2.9 xr4x4 back to the road. Did my first show, soon as i sat in the queue at the gateway it cut out and refused to start! It did start after alot of trying and swearing but did not want to know at all after i luckily got it parked up. Once left to cool down it fired strait back to life, its been the same ever since, drive it anywhere let it idle and it dies again. If i try to restart it i can not hear the fuel pump prime but fine when cold. I dont know if somthing is over heating causing it. Maybe somthing simple or overlooked. any help or suggestions greatly Appreciated!! Thanks
