    dinala ko kanina sa car repair dahil dalawang beses namatayan sa daan at hirap din magstart. chineck nila ang fuel pressure at malakas naman ang sirit ng gas. pinacheck ko sa electrician sabi niya maluwang yung connection sa computer box. sinecure niya at umuwi na kami. under observation as of now.
    malamang yang maluwag na wiring ang dahilan ng problema. My previous experience ako sa 2002 Lancer MX na random na bumababa ang rpm then balik na naman sa normal speed. Hirap hanapin hanggang kinalog ko lahat ng main wires habang umaandar ang makina. Ayon maluwag na wire connector ng ECU to +12V ang culprit.

    The mechanic today theorized that it may be the coil or the pump. He checked the coil and found it was ok. Then he tried to replace the old fuel pump with a spare one, did a test run and bingo! Ok na ang drivability. Fuel pump nga ang problem. Wala ng hiccups on my way home, smoother acceleration specially when up shifting, noticeably more torque even at higher gear and better throttle response. I bought a surplus pump for 1200 and labor 500, (tank had to be lowered for access of pump for this model) then nagawa rin yun fuel sending unit na corroded ang connection. Case solved finally!
    Thanks tsikoteers!

    nka MAF sensor nb ang singkit khit nka ECI? ganun din kc problem nung skin. if nka MAF yan baka pepede cguro? wala bang status s panel m sir like check engine or what? mine kc nlabas check engine status... au2 k is GLI lancer 94 model all manual ECI multi din but I am using MAP sensor not MAF.

    autonkoyokot, GTI po yung singkit ko. EFI multi, all power.Eto yata and unang singkit na fuel injected at all power. Meron itong MAF at intake air temp sensor dun sa may air filter box. Di naman yun ang problem kase wala namn check engine light at probe ko ng VOM multi-tester, ok naman. Ano problem ng singkit mo?

So kung sunog ang relay ng Fuel pump mo, putol na connection, dapat di na tumatakbo yang auto mo. Tingin ko linisin mo muna gas tank mo. Kse pate ung guage sa loob ng fuel tank mo nagloloko. And wala naman CEL dba? kse kung tune up kailangan nyan or sensors, vacuum, ignition timing...etc. meron na dapat Check Engine light sa panel guage mo.

    Anyway, nabaha ba auto mo?
    I just want to share the definition and function of the relay in a vehicle. The relay is an electrical device that opens or closes a circuit or circuits in response to a voltage signal. Now, why are we using relays in our vehicles?
    The contacts of the relays are large enough to carry high or sufficient load current. Notice the common vehicle relays that are used, like the bosch. There is a mark 30 amps. Meaning it's contact can carry as large as 30 amps load current compared to the common or ordinary contacts of a vehicle switch. That's why we are using a relay in a vehicles. Now what the ordinary switch does is just to open and closed the relay coil who has a small amount of load current which will not burned out the contact of said switch.

    Furthermore, the relay NEVER LOWER the current in your vehicle WIRES. If these relays lower the current passing through the vehicle wires, there will be voltage drop in your vehicle electrical system and any device connected therein will not function or operate normally.

    Kindly refer to the internet how are the LOAD, SWITCH & VEHICLE RELAYS are connected to fully understand the above.

    try mo magpalit ng ignition coil. tingin ko pareho tayo ng problema sir. pero sa unit ko dalawa ang ginawa ko na alam kong yun tlaga naging problema ko. pinapalitan ko ng mga capacitor yung ECU at pinalitan ko ng ignition coil.

fuel pump problem kaya?
