Hi everyone

[Stevebd]

Need some advice on an intermittent fault on my sprinter. Van starts and runs. Sometimes pulls back under load. But worst after a run doesn’t start probably for a hour. Then is good again. Have noticed that when removing the fuel cap there is suction. No visible bubbles in fuel line.injectors have been done.
Thanks for any input
