Pride LX 98 engine dies after ingnition

[blue&red]

Hello!

My family owns an LX Sedan 98. Its been with us for the past 5 years. it is a reliable car, I should say, with its 1100cc engine...you can go far. Only now, though most stock parts have been replaced already, my utmost conern is the idle of the engine. Just recently we discovered that after ignition, the engine just dies after 2 mins. though our mechanic says that a defective fuel pump is the culprit, I just wanna have some other opinions to rest my mind. Recently, we had the fuel line from the fuel filter to the fuel pump (rubber hosing & filter itself) replaced. The car performed perfectly until the new problem arised. It is a main concern for me since I drive our car long distances, manila to laguna and back and I don't wanna encounter that problem along the stretch of the SLEX. Any advice on any other possible causes will be very much appreciated! thank you very much and more power!

Welcome to the forum.

I believe the only way to diagnose this is to attach a fuel pressure gauge and confirm the fuel rail pressure.

Just to confirm, does the engine run if you keep your foot on the gas peddle and only die when it should idle? - If this is the case, then you have a problem with the Idle Speed Control (ISC) valve, which can often be cured by cleaning with Carb Cleaner.

It could also be a problem with the EGR valve, but this normally makes for rough idle and poor performance.

I appreciate your advice Ron. Thanks! :-) unfortunately we weren't able to observe the idle of the engine when pressure is applied on the gas pedal. we'll try to do that.

the fuel pump may be the culprit (but your car must not be able to restart after this since the 2 mins is supposed to be the fuel reserve in the carb). try to change your fuel filter...also you might want to check if there is water in your fuel filter. if yes, then your fuel tank has a hole somewhere through which moisture / water seeps / condenses through. usually the hole is located in the steel pipe from the fuel intake leading to the fuel tank. this pipe is located behind the left rear wheel where mud / dirt and water are kicked up from the tires all the time.

hope this helps.

I just realized that my comments are more in line with a fuel injected system, whereas your car is likely a carburetor, and in that case hanzel371's comments are more appropriate.

thanks for the advice hanzel. my mechanic found out that the fuel line is the culprit. it so happened that the rubber hosing was bent too much to the point there is no more gas flowing to the filter then up the carb. nevertheless the problem was addressed. Thanks again!
