cefiro engine warning light blinks

[marvs]

mga sir pa help naman po.
Yung 1998 nissan cefiro namin nagbliblink yung orange light that says "check" sa dashboard pagnakalagay sa on yung susi tpos pagstart mo hindi tumutloy umandar yung makina parang alang umaakyat na gas sa makina pero sabi ng mekaniko malakas naman daw yung buga ng gasolina, kahit sagad na tapakan yung pedal ayaw parin umandar. Before that happens nilinisan namin yung mga fuse sa ilalim ng steering wheel tapos check namin kung may busted ala naman po then the next day ayun na lumabas na yung sakit niya.
sir what could be the problem napalitan na namin yung spark plugs ganun parin tapos sabi ng mekaniko baka may problem sa kuryente or computer box na.

I believe the reason for this trouble could be electrical. Somewhere from the battery/alternator system you are losing power. It could be a loose wiring connection or it could be a broken wire after you have clean the fuses. I would think that any garage would be able to find the problem easily.

kailangan mo diyan shop na may scanner para ma check muna kung may hard fault

^ I agree. You need to find out what's triggering the CEL so you can work methodically. Without knowing the extent of the "maintenance" you or the mechanic did to clean the fuse box, it's hard to tell what went wrong or what connectors were moved/removed.

It would also help if you have access to your car's shop manual if the owner's manual does not have comprehensive servicing instructions.

You could also try disconnecting the battery for a few minutes and see if all it needs is an ECM reset (assuming the ECM memory gets erased when the battery is disconnected). Not quite familiar with Nissan ECMs.

Does the engine crank but does not start or no sound at all as in really dead?
Best is to have it scanned para di trial and error method.
