Possible Computer Box Problem..Help anyone?

[gabygab]

Greetings Tsikoteers!!
It’s been a while that I’ve posted a Thread here. I just really need some inputs from all you experts out there. Medyo mahaba yung kwento, so I hope you’ll bear with me.
So here’s the info, before magkaproblem yung car. Gamit ko sya nung Friday, then parked it late night na. Then hindi sya nagamit for 3 straight days, exposed sa non-stop rain nung weekends (sa kalsada lang kasi parking). Hindi naman nabaha, basang basa lang sa ulan. Lagi naman syang ganun pag nag-uulan.
Now, nasa Talyer car ko (a 96 Toyota Corolla Gli Bigbody, 4A-FE Engine), problem is it won’t start. May cranking/Redondo naman, hindi lang magtuloy yung andar ng makina. I even changed the battery (Enduro 2sm) and spark plugs (all 4 of them) as part of isolation. Car still won’t start. Also verified that all Fuses are OK, may sirit naman yung gasoline papuntang engine,and there’s current supply going sa distributor. One thing noticeable though is that hindi umiilaw yung “Check Engine” light sa console whenever key is turned ON.
Upon continuous isolation by a mechanic, here’s the findings:
1.) “Check Engine” indicator won’t lit when key is turned ON. Try to start the car on this situation, Car won’t start.
2.) After may sundutin dun sa main power line that supplies the distributor(using a probe connected sa positive ng battery, and key is turned ON), “Check Engine” indicator will lit. Try to start the car on this situation, Car will Start!
3.) Kaso pag pinatay mo yung makina, then try to turn the key ON uli, wala na namang ilaw yung “Check Engine” indicator. Hindi uli mag iistart yung car, though may Redondo/cranking.
4.) So, sundut uli dun sa main power line, as if sya yung magti-trigger para umilaw yung “Check Engine” indicator. Once nakailaw na yung “Check Engine”, mag iistart uli yung car.
So after some grueling hours of isolation, a repetitive1.) sundot sa main line,2.)iilaw yung “Check Engine”,then maiistart yung car,3.) Pag pinatay yung makina, then turn ON the key, wala uling “Check Engine”. Car will not start again.
Here’s the kicker. Yung Computer Box na nung auto ang napupuntiryang culprit. So, we’ll bring the computer box sa Banawe tomorrow for possible repair.
So there po, yan po status ng car ko now. Are the isolations OK? Did we miss something? Tama po ba pinatutunguhan namin for the resolution ng problem? Hope to here from you friends…

Many Thanks

Check muna mga fuse kung may busted na. Kung okay mga fuse ay possible sira na contacts ng Ignition Switch. Spray ng contact cleaner ang mga contacts at connector ng Ignition switch. Pero kung di ka marunong mag DIY ay palit kaagad ng Ignition SWitch.
