problem with my pajero

[johnart]

hope for anybody's idea what would be the cause. Vehicle is a Pajero, automatic 1999 model, 2.8 diesel engine, mileage is at 53,000km

Here's the problem hard starting siya sa umaga. As long as it had stayed overnight parked. After I put the key and turn it I wait for the heater light to dissapear then I start the car. Now here's the weird thing the cars starts then after a few seconds like 10 to 20 seconds the cars starts to shake, smokes white smoke and dies. After this the real problem starts when I try to restart it takes a long time for the engine to start. I just keep on cranking the engine but it does not want to start. And when it finally starts the whole cars shakes and smoke a lot of white smoke and also dies. For me to make the car run and not die again , I have to step on the gas rev it at 1k. But the rev at 1k fluctuates between 800 to 1k. Its like I am stepping on the gas and releasing then stepping but in fact naka pirme lang ako. And at this stage the whole cars smoke even more white smoke and shakes. This takes at least 2 to 5 mins evertime I try to start the car. Now what could be the problem. This started a day after the summer has ended. Or when the temperature in the mornings started to become cold.

some of my thought and diy to fix the problem but failed

1. carbon cleaning after having it done I have my fuel filter changed still the same.

2. Before having the fuel filter change about 2 months ago and 200 kms before I used biodiesel with a concentration of 80%. The whole carbouy was filled in the tank when the fuel light lit up. around 20liters sa carbuoy and less than 10 liters sa tank.

3. I thought it could be the heater plugs ? Had then changed at 25k km ago but the cars starts naman pag 1st try and just dies afterwards. Kaya I ruled this one out.

4. Thought it could be overhaul kailangan na . But wala naman oil consumption and the oil is new around 500km palang.

am out of ideas whats your thoughts

I'm not sure but you can also check your fuel injection nozzles. puwede ring glow plugs din, parang kulang sa init, kaya it starts and dies, kasi when I went up to Baguio last December ganun din nangyari sa akin. but when I got back to Manila okay na naman.

salamat sa reply sir, sige po try ko muna ang heater plugs bago ang top overhaul. sa mas mura muna

It's gonna be a strike-out process:

Try to check first your glow plugs again (did you use OEM or replacement?). Also, go over to a diesel center to have your injection pump, and nozzles checked as well (maybe they can also do an engine compression test).

i had the same problem with my 2.8 pajero very recently and solved it by changing the glow plus, glow plug sensor, and finally the fuel filter. It took me two weeks of trial and error to get it. At the end, its just the fuel filter (barado na pala).

baka nga glow plugs. had them changed 2 years ago. I hope its original ang it was replaced sa union motors ko pingawa. Thanks for the suggestion will go to a diesel center to try to elinimate the problem

sir glow plugs sensor ? saan po yun ? The fuel filter just changed around 1 week ago. marumi nga yung luma because of the biodiesel. Mileage since last fuel filter chagne around 150km. So pwede ko na rule out yun. Up to now I just leave it in the garage and start it twice a week and not use it muna baka biglang ayaw nang magstart. BTW could it be possible that the battery could be the culprit ? its exactly 3 years today. motolite maintenance free. pero nilalagyan ko ng battery fluid para tumagal.

di naman cguro battery..since it starts n cranks with no prob.

could it be possible that the power being sent to the glow plugs from the battery is weak ? Just exploring what could be the main culprit

sa tingin ko din glow plugs.. before ung pajero ko hard starting din, un pala ung isang glow plug sira na.. apat ata un..

Exactly the same problem I encountered with my starex, the culprit, a clogged screen (filter) at the inj. pump inlet. I don’t know if your pajero has one though…

..am not comfortable with a 3 yr. old battery on any vehicle with auto tranny.

its possible pero bakit kaya sa starting lang siya. After warm up ok na ang sasakyan

With the battery naiinip na nga ako tagal masira. inaabang ko na nga.

[BlueBimmer]

palitan mo nalang battery then sell ur old battery sa mga shop

pwedeng glow plug or baka may air yung fuel line mo, hindi maganda pagkableed nung pinalitan ng fuel filter.

[Field Master]

Can somebody post fuel filter bleeding process for 4m40 engine. I'm experiencing Johnart predicament too but not that much. Thanks.

pero sir pag may air yung fuel line dapat kahit nag warm up na palyado yung sasakyan. Pero ang nangyayari ay maganda na ang takbo basta naka init na ang sasakyan
