Will not consitantly warm start - 1.6jx

[Gary.]

OK Guys, here I am again asking questions. (I have read extensively through many similar problems on this forum).

I'm still running in my complete re-build 1.6jx (400 miles). It starts cold, if not a bit spluttery with cloud of blue / white smoke. Then clears up and runs & drives awesome!

The issue comes when trying to start warm (update: actually fine when hot). It just cranks over and over, say 5-10 seconds at a time, sometimes starting, sometimes killing the battery.

The glow plug light does not come on when warm, but did before it was rebuilt? I don't want to add a resistor to the glow plug temperature sensor, I'd rather get it bottom of the problem and have as close to manufacturer spec engine as possible. Simple questions, could anyone follow up with pictures?

• Where is glow plug temp sensor on 1.6jx syncro?
• Where is 50A glow plug fuse (could not see it on fuse board).
• I've seen air bubbles run down the clear pipes from the filters to the engine, is this right?

Thanks in advance.

Sounds like mine! Apparently these engines need a touch of glowplug when hot as well as cold
Glow plug sensor is rear of cylinder head, one of the wires is blue/white. Try unplugging cable to see if glowplugs operate.
Glowplug fuse is in the black box in the engine bay, upper left of bulkhead.
I've also got a few bubbles in the diesel lines so not sure on that one!

Thanks. Will check today. The bubbles are coming down what appears to be the return fuel line (enters the top of filter).

I'd like add that it bump starts immediately!

I think this is the glow plug temp sensor, though the wires are a different colour, subsequently connected to blue/white.

My temp sensor for the glowplugs is on the rear end of the head, I think that's the one for the temp gauge in your photo
I think there's two in total on the diesels

To be honest I think where your various temp sensors are is luck of the draw after 30 yrs and goodness nknows how many owners. You can identify temp gauge sender by grounding it and watching the temp gauge rise. Then there are probably 2 more senders - one for additional water pump, and one for glow plugs. They are different sensors, I think and if you are lucky they will be wired in correctly. Follow a wiring diagram (from www. syncrosport) and trace where the wires from the sensors go into the connectors in the engine bay junction box. I'm afraid I can't help you identify the differences between the sensors. I think it's something to do with the colour of the sensor body. Etka may have details, also the BW webshop I seem to remember. The glow plug strip fuse is in the junction box to, if it exists.

For instance, while quattrodave has his glowplug sensor on the end of the head, that's the temp gauge sensor on mine.

Sorry to suggest your wiring may not be totally straightforward, but that's been my experience. Very few sensors connected at all, no earthing, missing fuses. All fixed now tho, and as a bonus I can read a wiring diagram too!

Blimey, that's a bit doom and gloom! Interestingly I've obtained a list of previous owners from DVLA, which there were only 6. (2 in the last two years!).

I've checked the relay for dry solder joints, seems OK. Reckon it must be the sensor, as when I disconnect, the light on the dash stays on.

Looks like I have an aftermarket temperature sensor, but can't find the right one on brickwerks. Can anyone find me the link? They look cheap, so I'll probably change that first.

Google " Brickwerks " go to search, put in glow plug sensor!
When my van is " warm" I pull out the cold start lever!! ( it starts immediately !)

The glow plug sensor is the same part number as the temp sender, so you can swap the wires over & see if that cures the problem. I've never had much luck with aftermarket senders, best go with OE ones.

I'm not that thick. Just they had a few listed and was not sure which one!

Will try the cold start lever trick first

[dave friday]

My reason for writing instructions is that the glow plug sensor isn't listed as such!
I just think people are as thick as me!!

This type of response happened to me early this week, people seem to be very prickly these days !
