Fiat Uylsse Engine Problem

after spraying ethanol into engine and it starts does it continue to run on its own.

if it runs on its own does it restart noramly when hot?

by the way the best way to test the heater plugs is measure the amps drawn by each plug no need to remove them.

i will wait for your answers

I had a similar problem with a Renault 1.5 dCi. Seems like these high pressure "pumpjet" style diesels have an issue with the injector nozzles eroding. Might well be you'll have to invest in that engine hoist.

As regards the glow plug issue - the other respondant nailed it, check the current draw on each as you turn them on. Used to be you could monitor this by watching the courtest light as you engage the ignition but not so noticable on modern cars.

If you ran out of fuel and put some in the fuel tank. Each injector has to have the air bled out before the engine will start.

Thank you all for your input. I decided to take the injectors out and have them tested. One of them was cracked another was blocked up. And the other two did not open.

These injectors are self bleeding so if the tank ran dry it would not matter.

The dashboard dose not have a light on it that would indicate the amount of current being drawn.

And the engine did not keep running when it got hot unless you squerted more ethanol into it.

so it looks as if i am going to have to flush the tank out and stop buying Tesco's fuel.

Thank you all once again but it dose look as if this is a common fault on this type of engine.

That is NOTHING to do with Tesco's fuel......

You have an engine problem that appears to be the injectors if I understood your post correctly....get them all replaced/rebuilt asap.

Usually, most modern diesels will start easily in warm weather and no glow plug heat up. But in winter, you will be in trouble if the glow plugs are not working.....as its now summer, I doubt if its the glow plugs.

You should also replace your diesel filter and make sure that its not full of water.....your fuel tank may need water removing, a bottle of methylated spirits to a full tank of fuel should do that. Do it twice.

Get your compressions checked, that is also a possible problem that would appear as you describe.......

thank you for this information as i had not considered putting methalated spirit into the tank.

The injectors are now being replaced with new ones.

Thank you all again.

Methylated spirits "collects" water, but do not over do it, 0.5 liter per FULL tank should be OK. Run the tank till its on the reserve then fill up and add another 0.5 liter.......if you want to do it twice, but do clean/replace the filter first.

Also some filter assys have a water collector that may need draining as well......

Meths tends to NOT lubricate the pump as well as diesel does, so that is why you should not over do it!!!

You can do the same for a petrol vehicle that has water in the tank, it does not damage those injectors at all.......

Water is usually the result of having an empty tank too often, the tank sucks in damp air and that condenses out. A full tank does not do this anywhere near as much.....

Always add the meths either in the middle of a fill up or at the end....never at the beginning...

My son in law has a Vauxhall with a petrol engine and his o2 sensor keeps coming on. He is always running around with the tank on empty. So if it is getting condensation in the tank it would be burning water which may be the cause of this light coming on.

Thank you once again for this information.

Its simple, cheap and it works well....

Tell him to be not so cheap and fill the tank each time.....
