Team Troopy
hi guys. i have a 97 troopy with a 1hz. it has become very hard to start on cold mornings. i have replaced the glow plugs, of which 4 were stuffed, but it hasn't helped. it is only getting 6-7 volts to the busbar, compared to the full 12 on my old man's troopy. does anyone have an insight as to what may be causing this? cheers, dale

Possibly corrosion in one of the connectors along the wiring path. Chase back through the wiring, pull each connector apart and
check it and the wiring connection into that connector.

hi team troopy
hi dont have a troopy but have a mazda bravo
most of the older sytems have a relay timer between the key and the glow plugs enroute in the wiring
i would guess that it is where you are loosing voltage find that and clean it's terminals or it may need replacing
also i found on my mazda the glow plug threads were allowing compression to escape found this when i was crc ing the side of the engine and put liquid pipe sealer on the threads which stopped the leaks and also made it start easy
hope this helps
cheers barry

hi
you could also do a compression
test via the glowplug holes it might be in need of a valve grind ?? depending on its km's travelled
old engines are like old people they dont like moving on cold mornings

yep, grab out your manual and find where the relay is hidden. Cheap plastic black box to replace. Hopefully it's an easy fix :)

There's also a thermostat in the glow plug circuit in the side of
the block,which cuts out the glow plugs when the engine is hot.
Mine was stuffed in my old troopy, also
check the spade terminals at the sensor for corrosion.
From memory the glow plug relay is somewhere behind the dash, glovebox area, or side kick panel.

I'm pretty had to start on cold mornings too Team Troopy, it was -5 degrees on my porch this morning. But like some of the other have said I think the problem could be the amount of power getting to the glowplugs or the timing of the glow. On my old GU Patrol...I had to wait about 30 seconds past when the light went out before trying to start....and it seemed to worked much better.

hi patrol22
you are on the money there
my injector serviceman also advised me to wait 30 seconds after the dash indicator light goes out on all the old type glow systems
and yep you get a good fire up every time with this practise the new systems are instant but the old ones slower to heat up
cheers

There are a couple of different glow plugs available on the 1Hz - hope you were given the correct ones for your model 1Hz.
