Ignition timing and fuel pressure check not done yet.
spark plugs lean or rich? I don't know, how to determine if lean or rich? but they are in correct specification. There was EGR code failure but is not showing up anymore and also my gas cap is not hissing when i unscrew it.
1/4 or 1/2 tank of fuel my gas pedal is hard to depress, and when my fuel tank is full engine light is not flashing anymore but i feel that it is still hard to depress.
spark plug cables for is ok.
Abt the cylinder compression, all four cylinder are in between 90-200 psi in 4-5 seconds.
I have the spark plug picture upload came from engine cylinder 1, picture is blurred.
I will send you a message next time again abt fuel pressure and engine time update.
Thank you very much[/quote:764b3de1a6]
Im back, oky ignition timing and fuel pressure okay. The next I did after that Is to check the voltages of those 2 wires going to injector coil, each injector coil has connected from 12 volts power and the other wire from ECM. I unplug the power injector wires, each of them has a power 12 volts, I checked the other wires coming from ECM i have .034 volts except the wires going to cylinder 1 has only .019 volts. could be a bad ECM? or wire is not properly connected to the ecm?
AFTER ignition timing and fuel pressure checked any other suggestion?
