    I check the injector one at a time and they all work great the problem as I see it is that the cable to the second injector stay with electricity and this cause that it stay open at all time and it flood the chambers of the motor.

    do you have a service manual?
    if you do then check the fuel injectors electrical connections for good grounding, many cars grounds get corroded with time and start causing issues. You can also clean the battery connections. I've seen some of the ground straps go missing on these pt cruisers as some just clip on like the one for the transmission mount.

You will need to unplug the suspected bad injector. Then using a multi-meter on the lowest ohm setting check the resistance between both pins. A good working injector has a range of 12-15 ohms. If the resistance is higher just replace the injector.

Now it starts but wont stay running unless i pour gas down the intake. if i do that, it will run as long as i am pouring gas down intake, as soon as i stop it stops running. getting fuel up to throttl


Year make and model ? The injectors will open with zero pressure.
They use a magnetic valve. You should have voltage on one side and ground on the other when they are working.

Dead cylinder number 2 bad injector number 2


use a digital volt meter,put it on the ohm scale check number 2 fuel injector should be 11 to 16 ohms if not reads zero fuel injector faulty.if numbe 2 fuel injector okay.use noid light hook it to fuel injector electrical connector with fuel injector disconnected and see if pcm is firing the fuel injector noid light should blink when cranking the engine.if light steady pcm not firing 2 fuel injector,if noid light dont light up.there is a open in the wiring connector 2 fuel injector 2. if fuel injector okay,check spark plug, carbon foul you have a bad ignition coil or wire if you see oil on spark plug you have worn piston ring or leaking valve guides allowing oil to foul out spark plug.do a compression test check compression to see condition of the cylinder.

My 2004 chevy trailblazer is missing badly. Had them read the code for me at auto zone and it said I had a miss fire on the number one cylinder. I changed the plugs and it is still missing badly


Try moving the coil pack from cylinder 1 to another cylinder (swap locations) and see if the same code comes up. If code is different, then coil pack is bad. Other reasons for miss; bad injector, poor compression.
Also, I know you changed plugs already, but always use AC Delco 43-103 plugs on this vehicle.

Service engine light comes on


It tells that your vehicule computer has detected a problem with one or some of tthe components. The computer then saved/stored a code to help problem investigation and turned on that warning light. A scanner has to be hooked up to the computer to get that (these) fault code.Visit your auto part store. They should put the scanner on and let you know the stored code(s) for free.
As soon you'll get it let us know and we will guide you identifying potential causes.
Hope it will help

Daughters 2002 Ford Escape starts but will not keep running. Similar problems since purchased it 1 yr ago. What could be the problem?


I have the same problem with my 2001 escape V6. there is a really cheap temporaly fix....actually it could be permanent and will never damage your vehicule. When u open the hood there is a plastic guard with the ford logo and engine size that is held in place with 3 bolts, 1 on the left 2 on the rigth. Unscrew these and the guarding comes off. Once this remove you will see the accelarator pedal cable hook to the throttle. U can rock the throttle manually to give more gaz when your motor is running. At the bottom of the throttle there is a small screw that is not touching to anything, if u screw it a couple of turn it will start pushing on the throttle and stop your vehicule from stalling. Adjust this screw until your RPM indicator on your dash board is at around 600 rpm wich is the normal idle speed of your motor when functionning normaly. The real problem is an air intake valve that is defective (150$) because it open when the vehicule starts but shut because defective causing your engine to stall because no air for combustion....By forcing the screw on the throttle the valve cannot shut down and that is why your vehicule wont stall........It takes a full 5 minutes to do the mechanical screw fix...And I drove one year on it before replacing the valve........good luck from a friendly canadian........
