Outer Limits 4x4 Board

On my 97 2.8td nissan patrol.

When I switch the key on to pre heat the glow`plugs the dash light flashs
and the engine will not start

Is the glow plug relay buggerd` As all my fuses are not blown

Any help Im getting sick of riding the pushy to work

Could be a faulty glow plug controller. Have a listen to see if the glow plug relay (underneath the flap next to the battery) is clicking when the key is turned to 'glow' There are 2 relays-check the smaller one on the right is clicking on. Also check blue and brown fusible links also..

Thanks I will check for that this weekend

Ive got the car going by running my own Power cable up to the dash
through a fuseable link to a switch.

Than back to glow plugs with a earth from glow plugs back to engine block.
Which has got me going but not fixed the original problem.

I know I can hear at least one relay switch on and off .

Thanks for your help i will post up how i go.

I think from memory, the system relies on on of the relays creating an earth for 3 of the 6 glowplugs. Only one relay should switch on at a time to avoid a short circuit....When the first relay turns off, the second relay which would normally have been supplying the earth return for 3 of the glowplugs, now switches on and supplys power for the other 3 glowplugs through its other set of contacts which are connected to Batt +ve..

Mines a 4.2 diesel, but what I find is I have to wait to hear the relay click off after the light goes out..... have you tried that to just listen for the click.

2.8 glow system works differently to that of the 4.2. I think the 4.2 system turns off the glowplugs a little while after the lamp goes out, then pulses them a few times after the engine has started--depending on temperature.
