Hi,
My car has been acting up for the past week and it's been on the tow truck twice. The problem had been the same all along, there's no battery light and check engine light when the key is at ON position. Only got oil, handbrake-is-on and door-not-tight lights. This caused the car to die (if it's running on the road) and won't be able to start but still can crank.
Just a sidenote, everytime I towed the car back to the workshop who did the halfcut installation job in Puchong Utama coz they knew the car better.
So the first time it died and cant be re-started was when I was about 200m from my house just driving slowly at 2nd n 3rd gear. Then called tow truck. At the workshop, they tested plugging in an ECU from a 6spd halfcut and it started right up (battery and check engine light lights up). So just let sifoo Wong rebuild the ECU and installed back into the car. I drove the car from workshop to home feels normal n nice.
Then next day afternoon drove to lunch still normal. But later in the evening while driving, the car died somewhere in Shah Alam. So canceled my meeting and called tow truck. This time I didn't stay long and just left the car at the workshop. The next day the mech called he said the car is fixed by changing the engine main relay. Sounds pretty simple. So I took the car and drove about 60km that day between puchong, subang and shah alam. All is good. Finally I went home.
The next day, while in the porch, I put the key at the ON position and saw no battery and CEL again. I didn't bother to crank as I know it won't start.
Then another next day, my dad and I inspected the car at the relay box area and wiring until we noticed that the EFI relay has no power coming to the coil when key is at ON (not getting 12V, checked with multimeter). As a result, the EFI relay didn't contact and the ECU didn't get a +B. When we forced contact the EFI relay, the CEL light comes on (no battery light), we have a 12V at +B of the diagnosis port and the engine can start. Then I look for a circuit diagram on the net and found that the EFI relay coil is connected to the IGN fuse. So we found that the IGN fuse located at the driver's legroom fuse box was blown. The spec says 10A but mine was installed with 20A wtf. So replaced with a spare 10A fuse and we have the battery and CEL lights on and the car started.
Then another next day (saturday), drove the car back to Puchong Utama for inspection. No prob so far. However I was curious and wanted to test a bit more. So I drove around puchong and suddenly the car died at the high speed lane in front of IOI mall in heavy traffic. About 15min later and being hated by other drivers for causing traffic jam, I got the car running again by installing another spare 10A fuse. So u-turn back to puchong utama, left the car with the mech, told him about the problems and took a bus home.
So overall has been a really frustrating week and appreciate if anyone can give some input about this matter. I will keep updating on the progress too.
Thanks
