Chevy Optra: Fuel Pump Replacement?

[talarms]

Hi Optra Owners!

I need your highly valued advise pls! Just towed my unit to Chev Pasig kanina, dahil ayaw umandar. The SA advised me na shorted na daw yung fuel pump ng unit ko, kaya walang umaakyat na gas sa makina.

Here's my problem. The cost of a new Fuel Pump is P15,200++. Does it really cost that much? Disposable ba ang Fuel Pump ng Optra? 1.6 liter A/T na LS ang unit ko. 2004 Model. Ang total mileage is around 50,000 km.

Is this really part of natural wear & tear, or is this fuel pump replacement premature? Where can I buy a replacement fuel pump for my unit please? No choice na ba ako sa tag price na P15,200++? Take note, cost of parts pa lang yun. Wala pang charges for Labor!

Other than Chevrolet / GM, where do you buy parts for your Optra's?

Thanks in advance & God Bless!!!

2004 wow! a very short time.

I cant tell you how long a fuel pump should last... but 15,00 just for the parts I dont know my friend I think its way too much for that price... that shouldnt be that expensive to replace.

If you want you can do a little diagnose yourself. The fuel pump which pressurise the injectors is at the back of the car near the tank. It normally makes a quick 'buzz' ( so listen carefully) when the ignition is switched on, if it is working. There is also the fuel filter there which can get blocked.
Finally try disconnecting the feed line to the injectors. Turn on the ignition.... fuel should pour out - TURN OFF QUICK!
If no fuel coming out, no pump. You can check also the fuel pump relay maybe bad.

Yesterday morning, when i start our optra, its hard to start, and when its start the engine didnt run normally, it was shaking like you fill a gasoline with a water mixture, and after a while the engine run smoothly, and my brother noticed that when the engine started he smell gasoline and he also noticed a black smoke coming from the exhaust, i checked and replaced the spark plug, but i didnt help, did any one here have experience it? i tried to go in chevy pasig for them to diagnose the car and it will cost me 1.2k, 1,200 php for diagnose? come on, so i decided to pull the car out of the casa, and when i got home i ask my friend who has a knowledged on cars he told me that maybe the cervo sensor of our car or the fuel pump needs a replacement, i need other advise. thanks in advance. god bless. by the way its 2004 LS A/T

ganyan din nangyari sa optra ko buti na lang under warranty pa kaya pinalitan ng wala bayad. nasa labas lang ng bahay ko at ipapark ko na sa garage ng ayaw na lang mag istart.

sa orig na gm parts meron yan sa fronte banawe. dun ako bumibili ng parts sa optra ko. nakalimutan ko nga lang contact number nila, tingnan mo na lang sa yellow pages directory.

Try calling Thunder, they import GM and Ford parts. They are always cheaper than CASA. I think they even supply parts to CASA.

You can ask them to refer a mechanic. You might get lucky.

Fronte and Nemerson also sells GM parts. Look them up in the yellow pages.

Thank you very much for your valuable advise! 'Pikit-mata' ko na lang ipina-replace ang fuel pump ng unit ko. Chevy Pasig me P11,000++ for the new fuel pump, from their original quote of P15,200++ They sent my defective fuel pump home with me, in a box. Till now, i don't know for sure if my pump was really beyond repair na. But when i did the 'quick buzz' test that you suggested, di na tumutunog ang old fuel pump ko. Wala naman akong technica na kaalaman sa makina. But the darn fuel pump is placed directly beneath the bench of the optra's rear seat. Thats also where my daughter's car seat is mounted. So i decided to bite the bullet, rather than risking anything worse!

my business partner's optra's fuel pump was also replaced two months ago. nag fabricate lang sila ng brand new fuel pump ng nissan sentra.

cost of everything is 3k, including labor.

I think meron nyan sa mga auto spare part... 1.5k lang... 15k is the whole assembly but you can replace the motor pump.. Ganyan talaga sa casa buo lagi ang palit...

Userfriendly,
Thanks for your inputs! Sayang i already had my fuel pump replaced! Do bale, thanks very much for providing us with the numbers of Thunder Auto Parts.

Sineater,
Perhaps you can take Userfriendly's advise and bring your unit to Thunder Automotive Parts in QC. Ask for them to refer a good mechanic to troubleshoot why black smoke is being emitted by your unit's engine. Here's the address of Thunder Automotive's QC Branch (courtesy of Userfriendly):

121 QUEZON AVE., UNIT #201 (cor Araneta Ave.)QUEZON CITY
Tel# 732-9358 * 741-6218

Regarding the P1,200 cost for diagnosis. Casa's sometimes charge amounts like this, because they plug-in a OBD Tech-II Scan Tool to diaganose your unit's Electronic Computer Unit (ECU.) Otherwise we won't know what the 'Check Engine' warning is lighting-up for! It will detect which among the many Sensors of your unit's engine is faulty / defective, if ever. Nag che-check engine warning ba ang unit mo?

If you have it done in the casa, meaning you buy their parts and pay for the labor of their mechanics, they normally won't charge this amount anymore in your final bill. GOOD LUCK!!!

ID4LV Sir, good day! san po nagpa fabricate yung business partner mo ng fuel pump? nung model mo ng sentra ang ginamit nyo? ok po ba di naman nagkaron ng problem?

from cluboptra yung gumawa. hindi mechanic. parang hobby-hobby lang din nya. they used a brand new Series 3 Fuel Pump. Well, more than 3 months na nyang ginagamit, di naman nagluluko. actually, ganda nga ng takbo nung oto nung napalitan ng FP eh.

This will work as long as pressure rate of the pump is the same or close to the stock. You said he was from cluboptra? Or maybe chevyclub? Maybe he could help a lot of Optra owners out there.

Recently I replaced the fuel pump of my optra LS 2005. kapag sa CASA ka nagpagawa they will charge you with 15,200++ for the Fuel pump assembly, And 2,600.00 for the Labor. Sobrang mahal talaga presyo sa CASA kse nga Assembly ang ikakabit nilang FP. One problem I noticed with the optra's fuel pump is the fuel filter. medyo hindi maganda yung design kse flat type yung filter. Unlike dun sa pinalit ko na filter na parang may dome support to keep the inside shape of filter like a baloon. Isa pang napansin ko sa optra's FP ay yung housing, medyo naiipit yung filter kaya kapag nabarahan ng impurities ay hindi na makahigop yung FP. Kaya ang nagyayari ay ruogh idling and namamatay engine kapag tinapakan ang accelerator pedal. The first time this happened to me, akala ko may problem sa ECU. pero nung mapalitan ko ng DENSO yung FP, naging maganda yung andar ng makina at hindi na hard starting. Nag-modify ako nung original housing kse ibang yung shape nung filter sa ibaba. sa mga optra owner na nakakaranas ng ganitong problem, try nyo palitan muna yung FP baka kse ito rin yung problem nung car. tnx to everyone here, hope i-share nyo rin yung modification na ginawa nyo sa optra.

Sir larrysuerte/1D4LV,

I'm currently experiencing the same idling/engine problem with my 2004 Optra 1.6 LS. During cold start, the engine's RPM fluctuates (idle is rough). And sometimes during acceleration, the engine suddenly jerks. At first, I suspected the car only needed a tune-up. So I brought it to GM Shaw and had the spark plugs, high tension wires (1 had a crack), valve cover gasket (suspected of leaks due to oil found in spark plugs) and vacuum hose (has a crack) replaced as per their recommendation. They also had the throttle body cleaned. The whole thing cost me P5,800+. Their recommendation to me if the problem does not cease is to replace the "Throttle Body" which is estimated at P14,000 + labor.

Based on the thread above, I assume its the same Fuel Pump problem. Maybe you can share with us the name and contact number of the person that attended to you or your friend's car. This would help a lot of Optra users. Thanks. *

Symptom of an Opel Fuel Pump problem.

And this is the guy who helped by friend fix his pump. His handle is Vectra One. I think you can check out his contact number dito sa Opel Club. My friend kasi is out of the country. Try searching na lang Opel Club for his contact number. Dito rin nakuha nung friend ko yung number nya eh.

pre palitan mo muna yung fuel pump (surplus cost around P1000), yung fuel filter palitan mo rin nung nabibili sa auto supply (tin can type din cost around P280), and lagyan mo ng hose (8mm diameter, 700mm long) from intake manifold spare slot going to engine camshaft cover spare slot (inside engine exhaust pressure). Think this will solve the problem, yung sakin kse d na nagloko nung ginawa ko to. call me at 02973119323 for more info. larry

Bumigay din ng Optra namin dati and it was just in the casa for a tune up 2 weeks before this happened.
Sana nga gumana yung fuel pump motor ng cefiro. ito yung try gawin ng mechanico namin.
