google firing order diagram for 2004 chevy optra

Chevrolet Optra... | Answered 2 hours ago


There are 2 6 cylinder engines for that year. Both are the same as far as wiring/firing order but gave you both anyway(see below). There have been times that I thought I did the same thing as far as the firing order and have been doing it for 25+ years. Sometime i did and sometimes I didn't. So if you find the wiring is correct and you seem to have a miss, In about 90 percent of the time that this has happened to me I had knock a vacuum hose off so you might want to start there if they are right. It sure sounded like a miss at those times but was vacuum. There are other factors but that's where I would start if this is the case. I hope this helps and good luck.

If it will not hit with spraying starting fluid, that indicates that you have a no fire condition. Start at the spark plugs and work your way in from there. Wires, coil, crank trigger, fuse.

It's a fused circuit, so check the fuse, probably under hood, labeled injector. A shorted injector can shut down the injector drive circuit, so pull off all injector connectors, make sure fuse is good, then check for power to the injectors. Injector circuit should nave hot wire anytime key is on. Has constant voltage to injectors. When the computer internally grounds the injector ground wire, the injector will pulse.

in relation to the cruise control ????? There is no vacuum used for cruise control on your vehicle . Your vehicle has a computer controlled electronic throttle system .The powertrain control module (PCM) monitors the signal circuits of the cruise control switches in order to determine when to capture and maintain the selected vehicle speed. The PCM uses the throttle actuator control (TAC) module motor in order to control the vehicle speed. For further information on the TAC system, refer to Throttle Actuator Control (TAC) System Description . Your best bet , take it to a qualified repair shop. Need a factory or some other professional type scanner to check for codes an data input from the switches to the PCM
