Dispatch 2.0hdi Wont Start

[Guest dommez]

Hi there, i am having major problem with my van it ian an 06 dispatch 2.0hdi.

with no warning sign at all i went to start my van which usually starts no problem and it just turned over without starting i rang recovery guy who confirmed what i thought that there was no diesel getting to engine and that the in tank pump was the problem. I then bought and fitted a new in tank pump (£150.00) which made no difference, i then replaced coolant sensor as my temp guage was going mad, again no difference, i then replaced relay for fuel pump and still no difference i then noticed that my glow plug light is not coming on at all even at minus tempetures. a mechanic who had a quick look thinks there are broken wires and his computer showed up nothing? i am currently waiting on an auto spark coming out and hopefully he can help. has any one came across these problems before and if so what fixed it? p.s i have checked all fuses and other relays and they all seem fine. please help if possible this is doing my head in!!!!!
