The car electrician found out that the alternator of the Hyundai scoupe 1993 is not charging enough to the battery. They repaired and fixed the problem. A alternator brass copper was replaced and soldered. This time I don't have any problem on starting up for the entire 3 weeks.
Now that his able to put back everything, the moment of truth has come to see if the 4th cylinder of the hyundai s coupe will fire. But unfortunately it didn't solve the problem. However the mechanic was able to find the main culprit that causing my car to falter during acceleration, its the Fuel Pump inside the fuel tank. The Fuel Pump were leaking huge amounts of gasoline thus will causing not enough fuel to pump. He replaced the pump, this fix the faltering problem during acceleration.
The mechanic then ask me to take my car to the car electronic shop to check my Hyundai s coupe ECU or other electronic parts which is causing the 4th cylinder not to fire. He suspects fuel injector is not tune to inject at the specific time. It could be late, injecting not enough fuel or clogged up.
I brought the car to the shop and the guy check the fuel injector if its firing enough. He found out that the injector is not firing enough fuel. It maybe clogged up a bit. He may have to clean it or I have to look for the exact Hyundai s coupe 1993 fuel injector set. This can be costly. Just take a look at the video of how the fuel injectors fire intermittently.
A few days after, he removed the fuel pipe that was attached to the fuel rail and noticed a whitish liquid that spills out instead of pure gasoline. He concluded that the fuel tank might be filled with other liquid instead of pure gasoline. His conclusion was right, after draining out the liquids inside the fuel tank. This is what we found.
Fuel sits at top portion while the other liquids sits below.
All of the impurities were removed and we fueled it with 100 percent gasoline. At last this time I wouldn't have trouble on starting up the engine which has been one of the problems that I've been having with my Hyundai coupe car. Now I know why I have to wait for a couple of minutes to start it up that's because the water needs to sit below the liquids because it's more denser compared to gasoline. This car engine start up problem were now solved. The thing that bothers me though is that where on earth did other liquids is coming from? Questions has raised discrepancy with gasoline stations. Could they have mixed water and gasoline to their tank? What's the white liquid? Motorists should beware of this.
Continue to the fuel injector problem which injects a little amount of fuel might be cause by the impurities of the liquid. However the mechanic had to open up the top portion of the engine and clean the white substance that sticks inside the engine cover. If we haven't found that water and other liquids inside the tank, it might cause severe damage to the car engine. This could be harder to fix.
The fuel injector is now injecting perfectly after tedious clean up from the fuel tank to the engine. Compare this to the previous injection of the fuel injector, you'll definitely see a very noticeable difference.
Now that the fuel injector is firing perfectly, its time to check if the 4th cylinder will show combustion which I hope it will. But unfortunately again, it fails. These has lead us to the other culprit suspect which might be the ECU (Engine Control Unit) or the car computer box. ECU reset might able to help but we're not certain since we haven't tested it yet. However an ECU expert repair guy that I've talked on the phone told me that it may have something to do with it. ECU repair here is not expensive, it cost only 400 -900 pesos. If they think this is the resolution then I would definitely take the computer box to their shop. I will soon post the result here. So subscribe and stay tune.
