I have a 1.5 diesel Peugeot 106, it is hard to start when cold.I have new glow plugs what else could it be?

Answer 1

Deisel engines are always hard to start in cold weather. There is nothing wrong with it people. They don't start as well as gasoline engines. That's they all need block heaters in cold climates.

Answer 2

Have you fitted the correct glow plugs,Bosch or Beru are fitted in production. The glow plug duration is controlled by the ECU which determines the duration according to engine temp using the coolant sensor. The glow plug relay can corrode or malfunction.If all these items check out then look at diesel pump.
You didnt mention the year it may have a common rail system on late vehicles.I have given you instruction for rotary type pump without wiring connectors on injectors.

Answer 3

Possibly your fuel injectors are dirty or worn. Dirty fuel filter? Does your car have the cold weather package installed for the climate you live in?
I use a product called "Power Service" in my VW diesel 2005 Jetta. I use the Gray container product in cold weather months and the White container in the warm weather months.
I mix .64 ounce of Power Service per gallon of diesel for aid in starting, maximum cetane boost , system cleaning, and fuel lubricity. The new diesel on the market since about 8-9 months ago is VERY DRY, meaning low in sulfur content and will wear on your injectors even faster now than the old diesel fuel it replaced.
For example, if I put 8 gallons of diesel in at the fuel station I will add Power Service as follows: 8 gal x .64 = 5.12 ounces of Power Service. So I would round off and just add 5 ounces to that amount of purchased fuel.
I like the product and have used it for 1 1/2+ years in my Jetta since it was new. I watch where I buy my diesel fuel as well. Use a station that sells quite a bit of the stuff. I monitor my fuel economy as well. My 1st winter I was using some "Shell" brand diesel and my economy dropped to 36 mpg. I started an immediate fuel search for a better quality fuel. I found a fuel supplier where I regularly average 43-45 mpg in cold weather.
Check out the website listed below throughly and see what you personally think. Consider giving it a try. Wal-mart sells the stuff cheaper than anyone where I live, its like $15+ for 96 ounce container that treats 150-300 gallons, according how you choose to use it. I do the 150 gallon method. Email me if you like. Good luck.

Answer 4

If it is a high mileage car and you have already done the obvious (changed the heater plugs) then it's probably worn piston rings, not an easy job to do so get the compression checked first just to make sure.

Answer 5

You need to turn the ignition on and give the glowplugs time to warm up before trying to start the engine, remember diesels are not like petrols they do not start from a spark.

Answer 6

It defiently your ignition what 365 days is the vehicle is it factors digital if on of those mechanical or vacum develop or coil %. nomatter witch it relatively is initiate with new plugs and wires those are in many circumstances the reason for susceptible spark. replace your question with 365 days and motor length it is going to help beter answer your question

Answer 7

Could be the coil
get a recon coil and get the garage to fit it or fit it yourself and save money
Three or four bolts I think and its done

Good luck

Answer 8

Check your valve clearances. The valves can stretch causing you to have little or no clearance.

This happened to mine.
