You need to do or have done a pressure test, fuel pressure test, these high pressure diesels need a certain amount of pressure to even open the injectors, from memory I think its about 120bar at the injectors... if that figure is not reached, for whatever reason it will not start on the key.

Too whilst having that done you could do with having a diagnostic test done along with Live Data to see whats going on with the systems. Live data can tell you alot. Also, you can see the pump speed and if thats not right it wont start on the key either. You don't mention if you have had any warn lights on the dash at all. but if you have had an engine manaagement or Ser and the Glow light whilst running, you do need the diagnostic doing.

You could have a problem with the glow plugs but that is easily checked - check to see if you have the light come on on the dash for the correct period of time etc - and then check with a meter to see if you are actually getting power to the plugs for the set time, and the right voltage... I take it that you have already renewed the plugs.

You need to work through the above to get to the bottom of this but start with the glow plugs (test) thats the easiest and quickest.

Hi Oulmide, Make sure of the correct setting of the valve and crankshaft timing match marks. Inspect both sensors for correct operation (crank and cam shaft sensors) as it may be that either has been damaged during the work carried out. It is also very possible that the anti theft system has engaged, especially as the battery will have been disconnected. Regards John

Where is a 1989 nissan z24 4 wheel drive fuel regulator located? starter went bad, replaced it, fuel line had a leak, replaced it, fuel pump wont push fuel through it, bought a new one and now the truck...


Fuel reg. is connected to the fuel rail where the return line is connected, my thoughts are you mentioned air in your lines.. crack open fuel lines and run fuel pump to release air from lines. Pump then should prime all lines must be primed turn engine over to release air ( No Smoking) then tighten lines. fuel rail might have valve, (looks like tire valve) if so it is recommended that air is relieved at air valve

I have a renault espace m reg 1995. The heater fan is only working on the fastest speed and not the 1st 3 speeds. It is blowing out hot air so that is ok. Just the speeds packed up. Any ideas


its the thermal fuse on the heater risistor, if you remove the blower motor from under the bonnet and remove the heater resistor you can then buy a 79p thermal fuse from maplins and solder it on i have done it on all my espaces

Renault espace starting problems


I have a 2000 Espace and for years it has suffered from a non-start problem. It can be fine for ages and then, suddenly, there's nothing when you turn the ignition, not even a click. All instruments light up. It's not the battery. Does this sound familiar?

In my case, time and time again it has been what they call the 'firewire' connection on to the starter - the connection becomes corroded over time and fails to pass sufficient voltage.

If the terminal becomes too badly burned, where the voltage has arced because of a poor connection, apparently the only solution is to fit a new starter motor. But so far, in my case, it's just needed a clean of the connector and terminal.

By the way, holding the ignition key in the ON position for some time (30 seconds or more) can sometimes cause it to fire up.
