Pappazulu Posted January 13, 2021 Share Posted January 13, 2021 Hi all I've got a bit of a problem, in the cold my 1.8tdci 04 really struggles to start, the glow plugs lamp only comes on for a second or so then goes out, it takes a while of chugging and turning to get it started. In summer O have no issues at all. I've checked the plugs in place and are all reading 1.6 ohms. Could it be the relay? if so where is it? Many thanks in advance.

I have the same issue.I was thinking of replacing the glow plugs but being in situ for 17 years the opinion was to leave them alone.I always make sure the battery is fully charged.At the moment I try to only start the car when outside is above 6 degrees.Not perfect i know 👍 Quote Link to comment Share on other sites More sharing options...
Pappazulu Posted January 13, 2021 Author Share Posted January 13, 2021 Thanks, I have no choice about the temp and starting, work is work and all that. The plugs look new, as in, no corrosion around, and the ohms are in range. I'll test the temp sensor and relay and see where we're at after. If you're thinking if removing the plugs at some point, let them have a nice warm bath in wd40 or your preferred soak. Overnight is good.

Many thanks in advance. if you have continuity it seems like they are good. Have you put a meter on each glow plug to see if you are getting power to each one and how long for . 1 Quote Link to comment Share on other sites More sharing options...
Pappazulu Posted January 14, 2021 Author Share Posted January 14, 2021 I'll do that next, thanks for the tip. I suspect the battery might be wrong though, I've figured out its a AGM battery and everything I read points to Focuses' needing a Calcium battery. Any thoughts?

TomsFocus Posted January 14, 2021 Share Posted January 14, 2021 35 minutes ago, williamweb said: This battery is not in my car now👍 Ah, there's your issue! It's gonna struggle to start with the battery out of the car. For both of you, how old are the fuel filters? Diesel waxes in colder temps so a clogged filter can become more of a restriction in winter. 1 1 Quote Link to comment Share on other sites More sharing options...
Pappazulu Posted January 14, 2021 Author Share Posted January 14, 2021 This is the battery in mine at the moment, its the one that came with the car when I bought it. There's weird stuff going on too, like the doors locking randomly and the boot light glowing bright then low... I've heard that if the battery is charging incorrectly then the altenator could fry the battery? Is it true that I need a calcium battery for the focus?

Pappazulu Posted January 14, 2021 Author Share Posted January 14, 2021 The filter is new by the looks of it, no older than a year and a half I'd say. 1 Quote Link to comment Share on other sites More sharing options...

Pappazulu Posted January 14, 2021 Author Share Posted January 14, 2021 I plumb for a new battery and see how we get on... is it possible that the numpty who sold me the car could've put the wrong plugs in I.e. element too short? and if so would this make starting rough? The plug light only come on for a second or so, which on a cold morning seems a little short. Quote Link to comment Share on other sites More sharing options...

My light stays on for about 3 or 4 seconds.My advice is go to Ford and get the correct battery fitted as seen in my photo👍 1 Quote Link to comment Share on other sites More sharing options...

It should charge between about 13.5 and 14.5 if it jumps over 15.00 it will overcharge the battery and could damage other electrical components on the car 1 Quote Link to comment Share on other sites More sharing options...

nicam49 Posted January 14, 2021 Share Posted January 14, 2021 Hi Pappazulu, the glowplug light on the dash doesn't indicate that the glowplugs are heating up! When you turn on the ignition, it acts as a self test indicator and when it goes out it shows that the self test (of the car's various systems, NOT of the glowplugs!) has passed OK. Nothing to do with the glowplugs at all. (I know, I know) your best bet is to check that the glowplug fuse is good, ie hasn't blown. Then if you can, wire up a 12volt bulb in a bulb holder to test that the glowplugs are getting power by connecting it to the glowplug rail and battery negative or chassis. On my Mondeo, when I turn the key, the glowplugs get power for 30 seconds, tho' the glowplug dash light stays on for a second, as I said before, that 'glowplug' light on the dash isn't anything to do with the actual glowplug pre-heating period at all. Just thought: to test that the glowplugs are good, you have to disconnect them all and test each one seperately for continuity... you can have just 1 or 2 glowplugs burnt out and you'd have lumpy starting, but if you're only testing the lot connected together in parallel that won't show that 1 or 2 are burnt out..... know what I'm trying to explain? If you want to know the location of the fuse and relay, then let me introduce you the fordwiki https://www.fordwiki.co.uk/index.php/Fuse_%26_Relay_Information_-_Mk4 1 Quote Link to comment Share on other sites More sharing options...

This is the reason for needing a silver calcium battery over a standard lead acid. 1 Quote Link to comment Share on other sites More sharing options...

It's a pretty clever system and takes ambient temp, coolant temp, battery charge and load to decide how long to raise the voltage for. 1 1 Quote Link to comment Share on other sites More sharing options...
