Glow Plugs

FFS!!
Why this fixation with the glowplugs???

I've told you what the problem is back in post #12.


The truck is taking a long time to fire up and runs lumpy for a while until warm?
This is becase the diaphram has split in the primer head allowing the fuel to drain back to the tank. The smoke you are seeing on start-up is air in the fuel, hense the continuous cranking to get the engine to start because the fuel pump has to suck the fuel all the way from the tank!

I see others have suggested tests on the glow plugs, have any of them been done?

Consider putting a volt meter on the glow plugs and getting someone else to turn the ignition on, time how long the glow plugs stay powered up.

If we assume there ok, as there new and that as it's fine once temperature is in the engine, perhaps the timer side isn't keeping them on long enough...or in fitting them the connections to the plugs or the bar that feeds them are poor. You could work along the connections with an ohm meter and see if any has high resistance.

I had new NGK plugs put in very recently, I have just found out how to test the power to the glow plugs so am going to test them tomorrow when its cold with the help of a friend and see if they are clicking off too soon.

I guess because its easier to check the plugs?

How do I check the primer head diaphragm? I can try that tomorrow as well if its within my ability

Plus whoever finds the solution to the problem will get a case of beer :-)

Now it'll have 2 faults lol

...........
If you pump the primer on the top of the fuel filter it should get hard after 4-6 ish pumps.

........................
I tired pressing the priming button, it didn't seem to get harder after any number of presses, I stopped at 15.

How do I check the primer head diaphragm? .....

You already have.

FFS! Why not? Nobody knows if they are working or not so why not check?

He has said it didn't seem to get any harder. Harder than what? Harder than easy to press and no resistance or no harder than the resistance it already has?

One would postulate the perceived predilection that the glow plugs are at fault is probably prevalent possibly due to the invoice the OP has received from the garage.

I would be unhappy if I had paid someone to fix something and it was no better or indeed worse than before I had opened my wallet.

Having the same issue whether with hot or cold starting would to me anyway lead me down the fuel primer route.

I can pick up my case of Rattler from this Tuesday onwards.

I have checked the fuel primer, it is working as it should, I think when I tried it before I wasn't actually pumping it fully so it wasn't going hard. I gave it some good proper pumps and it went hard after 5 pumps.

Having measured the voltage at the glow plugs, I was getting 10.90 volts at first, then after 5 seconds it dropped to 7votls and then cut out all together after 15 seconds.

I just did the ignition on four times, which with my measurements would mean the glow plugs where getting good voltage for 5 seconds, 3 or 4 times in a row.

It started quickly without the clouds of smoke, it still needs to be left ticking over as if I put my foot on the gas it smokes. This makes me think if the glow plugs where on for the 120 seconds they should be then it would warm up quicker.

I think my starting problem is being caused my the glow plugs cutting out too quickly. Would replacing the relay solve this problem? its not a cheap one at £50!

Cheers again

i wonder if you have a temp sensor problem and ecu is turning off glows to early.

have a word with Andyverran, breaking a surf, might have a relay.

I'll give him a buzz. A reply is easier to change so if I can get one cheap ;-) then it's worth a punt!

Easier to change a relay
