306 1.9 tds had a shunt wont start

[scorbitt]

i shunted my car into a lampost damaged the front left wing and mounted a kirb which bent the rear axle,,had the back end up on stands to replace the rear axle when my mate turned it over when it was in gear and it rocked off the stand and put a hole in the tank,iv replaced the tank, pump and glow plugs primed the pump using the rubber manual primer and it wont start,everything seems to be in good working order but it just doesn't want to fire, any advice on this is greatly apreciated, cheers,,also does anyone know a base price for a garage to change the front inner wing as its kinked and im not sure if it will pass the mot, thanks again.

Whats the year? It's important as pre 99 they had XUD engines, but later ones had DW10 HDi engines, which are completely different systems. As you mention changing the glowplugs and the pump and rubber primer I reckon it's a pre 99 with an XUD engine.

What happens when you turn it over- do you get clouds of whitish smoke from the exhaust or nothing at all? If there's smoke, then fuel is getting through to the combudtion chambers at least, but just not igniting. That would point to either an air leak in the system somewhere which has occured when you changed the tank over (check ALL the pipework and joins) or the glowplug circuit isn't functioning (check for 12v at the plug terminals)

If there's no smoke at all then assuming fuel is reaching the pump (don't assume the rubber primer is working- they're crap.....remove the fuel pipe to the pump and eyeball diesel coming through...) then you're looking at an electrical problem. The immobiliser is tied into the pump, and the pump is coded uniquely to the car, so the car maybe just doesn't recognise the pump. Put the old pump back and you may get lucky.

A number of diesel engines have emergency cut out switches that trigger on an impact. There is often a simple reset button.

I'm afraid I don't know about yours but it sounds like this might be the case. Check the manual it might just be in there

I know that Fiat and some French cars have a little ECU in the wing area - that may be your problem - It may just look like an innocent little metal box about the size of a fag packet with a couple of wires going in and coming out - but it'll sh*g up everything - you may be looking in the wrong area altogether. I had a Fiat Tipo years ago with the same problem.
