Bat starter all okay cranks over no problem, just seems that a stop is on the pump no white smoke, not fireing at all, jump start does not help, checked all connections and relays okay. Towe van 30 feet and starts, runs fine stop it and have to towe it again, hot or cold, have found a black plastic coil and circut around ign. switch wonder if there is a way to test? or by pass,?the key is just a plain key no buttons to press, would welcome any suggestions, as hair almost gone!!

Sounds like cranking the engine over is for some reason triggering the stop solenoid.

Now its years since i tinkered with a stop solenoid, the last time was on a CAV pump, to check it was indeed stop solenoid problem i removed the solenoid, removed the plunger within and refitted the solenoid, that proved the fault, and my mate simply had to stall stop the engine for a couple of days till a new solenoid could be purchased.

I couldn't tell you if the solenoid is live when stop or run, its been that long and it could be something entirely unrelated, but you could hot wire the solenoid directly and have a play about.

edit..have you tried pumping the fuel primer up before trying to start?

Many thanks for reply, it was CAV pumps that I worked on years ago as well, there is 5 volts at the stop on the pressure pump, and disconecting does not help, but I will try your suggestion of taking it a part.

The electric pump is working fine, just seems like an immoblizer is on and towing it seem to by pass it.

Many thanks Carbel

As this is an HDi engine,there is no stop solenoid on the fuel system.The electrical pick up ring around the steering lock is part of the immobiliser system,if this was faulty ,it would not start at all.You really need to get the fuel system pressure tested,Anything less than 150 bar and it will struggle to start.hth

Yeah,I think you should STOP what your doing right now!

that is NOT a stop solenoid,hdi's don't have one,your fooling around with sensor voltage,could be any or three and none of which are stop solenoids.and it's meant to have 5V

And please don't be tempted to remove whatever your playing with,these high pressure pumps run at over 200 bar at idle speed,200X14.5 is a lot of psi's,a dangerous amount.killing potential!!

anyway to help,you need a live data read of the fuel rail pressure,as I stated it has to be over 200 bar to start,if you tank fuel pupmp is weak,or the lines or filter blocked the it'll never get to the right pressure,same thing if one of the injectors is leaking too much fuel back,no pressure

It's not like the old days you have to start with a code read,then a live data and injector leakback test,if not you could end up like the Traffic I just got in,new turbo,new injectors,new AFM,maybe more,that's what i found so far all in a wasted money effort to get it to start,bad advice from bad people?who knows,my prelim is pointing to a faulty tank pump,it like yours seems to be working but I'll wait until I can live data read it.

Oh and a real rough and ready test is uncouple the fuel line and trigger the pump to run,it shoudn't piddle out,should squirt a good 3-4 feet,but that's no substitute for code/live data reading.

And again be careful,this is a very high pressure system.

I would agree with low rail pressure, when you tow the vehicle you are turning the pump much faster which is raising the pressure.

Injectors with internal leaks can cause this, try disconnecting the leak off pipes and running each one into a receptical and check if they are all leaking the same ammount, if the leakage is excessive on one, that's likely the problem - of course you have to get it started first.

I would like to thank all that have answered and given advice, the problem was the injector pump, I am a lot poorer now but have a deluxe model that starts by the key, the wife seems happier as well, now that she is not acting like fred flinstone and pushing any more.

Once again a very big thankyou.
