Why does my rodeo diesel 2.8l 99 model when cold starts at accessories point & glow plug light stays on longer?

Little bit of grey smoke comes out on start up. only when cold in winter it starts up at accessories & not start position & the glow light stays on for 5 seconds longer. it doesn't idle well & have to warm up for 5 minutes. after its fine no issue at all

Sounds as though the cylinder,s etc are a bit clogged up, try some diesel fuel addative,as with all diesel engines if they do not get long and regular journeys the glow plugs,injectors etc get clogged ,as the engine does not get hot enough to burn these deposits off on short stop start types of journey's . you are possibly looking at replacing the glow plugs but give the addative a try and if possible take for a long drive 2-3 hours at steady highish speed , ok to repeat the addative and long drive once more ,if no improvement will need to go into the repair shop to have the glow plugs seen to at the very least , good luck

SOURCE: stalls and wont idle when cold

Re the trooper. You have a couple of possibles. The most likely is the glowplugs or glowplug relay. Don't be fooled into thinking glow plugs only heat to start - the also do whats called postheat. That is to raise the cylinder temp until the block is warm. IF they are not functioning (clip a light onto one whilst switching the glowplug on to test the relay) this is common.
Most likely is a stuck EGR valve - stuck open so running a very lean mix when cold. Its two bolts on the inlet manifold, pulls out and looks covered in soot - it should push in and spring out. Can be cleaned in petrol or alcohol or with compressed air.
More remote is possible you have a faulty injector...only really testable by an engine centre...

SOURCE: 99 isuzu rodeo dies after starting

As your lights etc. are flickering too; check the engine; alternator; and, frame ground cables for a tight clean connection As your alternator charges your battery and, your starter just starts your car you can rule them out.

SOURCE: diesel rodeo dies and lack power when cold and in winter

Try changing the fuel filter and get the glow plugs checked or replaced .Diesel goes a little waxey in colder weather making it harder to go through the filter .
Hope this helps.

glow plugs are activated if look on the dash when you turn the ignition just before cranking and you should see a light that stays on for several seconds then goes out and then you should crank the engine ! sometimes when its really cold or the glow plugs are worn try turning the ignition on and off each time light goes out 2 or 3 times to get more heat on the plugs then start ! if this doesnt work then glow plus and system needs checking !

time for replacement of or severe cleaning with fuelinjection cleaner..also if diesel, add cold start to the fuel system..check and replace oil filter type fuel filter since jelling of fuel may be a cold start issue..crack open an injector line and see if injector pump is pushing fuel really well..and see if air cleaner needs replaced blackened element is not good..good luck..

Your diesel requires the glow-plugs to heat up to start when cold. This is why the truck smoked excessively when you pull it to start the motor. Siince you are not having the glow-plugs warm up via the "Timer" for them and you are getting intermittent Solenoid response from the tickler wires on the Solenoid, there is one common point.

The Ignition switch is the common point. You should also observe if your "Start" light is getting the feedback from the glow plug "Timer". Replace the Ignition switch and see if you hear the "Timer" clicking before a cold start. You can also take a 12 volt test-light or gauge and check the wires to the glow-plugs when cold. The glowplugs should be getting power from the until the glow-plugs heat up.

Remove and check the glow-plugs. A good way is to remove all of them, and take some jumper cables to each briefly. BE careful as they can melt and you can ruin the threads with the jumpers. Comparison is the best way to describe testing them. They should heat up the same for all. The glow-plugs that stay dark the longest are bad.

Ask the auto parts place if they show an Ignition relay for your Diesel. This would cover the poor starts when warm. Also tell them it is a Diesel when getting the Ignition switch.

if the glow plugs are originals they may need replacements soon.The starter can be removed and bench tested easily. If mounted in a vise securely you can test it direct for drag

I have a 1998 1.8 diesel van, once its running its ok, but getting it started can be difficult (esp in cold/damp) Have you got any tips for starting, does this model have a heater plug, if so what symbol...


Sounds like the glow plugs are frazzled. There is one electrical wire going to a plug, then each plug is connected in sequence. The glow plugs are heating devices used to get the fuel up to temperature before ignition.

They are fiddly to replace, but are relatively inexpensive and the most common source of issues with cold-starting diesel engines (first thing to fail).

Some cars had a 'pre-heat' available with glow plugs, where you simply turn the key part-way to 'on' and you would see a glow plug light come on (looks a bit like a picture of a spring). If you see this light on your van, you can turn the key to turn on the glow plugs and they will pre-heat your engine slightly and make starting easier

88 f250 diesel ticks hard pumps smoke still starts good and no power loss, took vavle cover off and everything looks ok wat should i check next wat would i look for if i was to pull injectors


The problem is the glow plugs are bad or not coming on. Even though the "wait to start" light comes on, the glow plugs may not come on. I have found when this happens, the light comes on for only 1-2 seconds and goes off. With the engine cold, the light should stay on for about 5 to 7 seconds. The colder the engine, the longer the plugs should stay on. There is one glow plug for each cyl. The plugs are in the "V" of the engine and screwed into head. Only one wire goes to the glow plug and the wire runs from one plug to the next on each bank. You test them by removing them and grounding the body and putting 12v positive to the terminal. The tip should glow red hot like a cigarette lighter. There is a glow plug relay behind the air intake horn which also could be the problem and there is a engine temp sensor in the circuit also.

Grey smoke from my ford mondeo lx 2lt tdci 2001 when i first start it .


hi from uk if you have to turn engine a little longer than normally? on initial start fro cold? and then starts/runs ok for rest of day ? then more than likely your engines glow plugs are in early stage of failing/burning out? these engines rely on pre heat of cylinders when starting especially from cold so they have glow plugs for this purpose indication of burning out is the grey smoke you report on cold starts this is fuel that is not being combusted due to poor cylinder compression/s being heated on first start but when engine heats up no problems so i suggest you renew all 4 glow plugs they are easy diy job and you can purchase from good motor stores not necessarily dealers they are just like spark plugs usually 10 mm socket/spanner to change em after disconnecting the elec supply cable from each hope this helps and inspires you? if milage is high then they are in need of renewal
