Just about to buy a 2003 vivaro.its had £5500 spent on it Recon g/box, new clutch, brakes, fuel pump, fuel lines, the list goes on. went to collect it the other night and would not start. left it eith him and he says he had had relay changed, both fuel pumps checked and still not getting any fuel. vans done 145k and is in mint condition with full histiry and a stack of bills with it. he wants £2100 for it. could it be something simple. plugged it into vauxhall computer and no fault found. checked ecu works ok. any ideas, or should i run a mile from this one.
