Fuel InjectorThis car has 170,000 miles on it. One  injector seems to be stuck open. When power is cut to the fuel pump, it will run until the fuel line is drained.

Is it possible that the injector is bad, or is it more likely that it is stuck open as the result of another problem?


I think you are right in your diagnosis. Fuel injectors do go bad and stick in the open position.

Identify the failed fuel injector.

  • Remove all spark plugs
  • Turn key to the on position- cycling the key may be required
  • Take note to which cylinder fills with fuel


HO2S and Air Fuel Ratio (A/F) Sensor Monitor and Readiness

NOTE: All readiness monitors are cleared when the battery is disconnected or when the
ECM/PCM is cleared with a scan tool.

Drive Cycle Procedure
1. Connect the scan tool.
2. Turn the ignition switch ON.
3. The MIL must be OFF.
4. The Engine Coolant Temperature (ECT) and the Intake Air Temperature (IAT)
should be greater than 41°F (5°C).
5. The Engine Coolant Temperature (ECT) and the Intake Air Temperature (IAT)
should be within 10 degrees of each other.
6. Do not turn the ignition switch off during the procedure.
7. Most OBD monitors will complete more readily using a steady driving style during
the acceleration and cruising modes. Operating the throttle in a smooth method
will help ensure and assist completing the monitors.
8. The fuel tank should be between ½ and ¾ full with ¾ full being the most desirable
9. Start and idle the engine for five (5) minutes with the A/C and rear defroster ON.
10. Turn the A/C and rear defroster OFF and idle the engine until the Engine Coolant
Temperature (ECT) sensor reaches a minimum of 170°F (76° C).
11. Begin driving and accelerate the vehicle until the vehicle speed is 56 mph (90
12. Release the accelerator pedal and keep it released for 10 seconds or more.
13. Accelerate again until the vehicle speed is at 56 mph (90 km/h) and continue
driving the vehicle at 53 – 60 mph (86 – 96 km/h) for 10 minutes.
14. Check the monitor for “COMPLETE” status. If the monitor status is not
“COMPLETE”, go to the next step.
15. Decrease vehicle speed to 0 mph (0 km/h).
16. Let the vehicle idle at 0 mph (0 km/h) 60 seconds.
17. Accelerate to 30 – 35 mph (50 to 55 km/h).
18. Drive the vehicle between 30 – 35 mph (50 – 55 km/h) for 5 minutes.
19. Decelerate to 0 mph (0 km/h).
20. Let the vehicle idle at 0 mph (0 km/h) for 45 seconds.
21. Drive the vehicle at 53 – 60 mph (86 – 96 km/h) for 5 minutes, holding the
accelerator pedal very steady. Monitor the Throttle Position Sensor (TPS)
voltage; it should be between 0.8V and 1.2V.
22. Decelerate (coast down) to a stop without braking.
23. Let the vehicle idle at 0 mph (0 km/h) for 45 seconds.
24. If the readiness monitor is still set to incomplete, check for a temporary DTC. If
there is no DTC, one or more of the enable criteria were probably not met; repeat
the procedure.
25. Allow the vehicle to sit (key OFF) for 8 hours and repeat the procedure.

2004 Volvo xc70Hello I have a 2004 Volvo xc70 and was wondering if it is possible to put a remote starter in it while using the original factory keys?


Of course you can install a remote starter on a Volvo xc70. The remote starter uses a key thob to activate the starter. The thob can be easily attached to any set of keys or carried separate.

Use the wiring diagram to help assist you if you decide to install a remote starter on your xc70 yourself. Make sure to disconnect the battery before you start installation. Follow the instructions provided from the manufacturer of the remote starter. Test the operation several times to insure you won’t have any issues once you leave home.

4cyl. has points and condenser. cold engine starts good, when warm will run at highway speed for 15-20 min. then slows down and will even backfire if you try to stay at speed but if you slow down to 25-30mph it runs good. it won’t run at highway speed again until engine is cool.  that’s not cool.

Drivers door window will lower when door is opened. When the door is closed the window will not go back up as Volvo windows do when convertible door is opened. I have to raise window with door switch every time I enter car. Window only drops down about a 1/4 inch as it always did. Does door window switch need replacement?

I am considering purchasing an ’02 Volvo V70CX wagon. It has 198k miles, but everything else, as far as I can tell, is in top shape. Here’s the problem: the owner says it needs linear shift solenoids replaced. That’s a little beyond my expertise. How much should a reasonable mechanic charge for that service? The asking price is nice, but not if the cost of repair is too high. Thanks.

I have a 2007 Volvo s40 that wont start in extreme heat! When its cool it runs fine, and I had to let it cool down for close to two hours one day! Anyone know what could be causing this?

I am having problems with both of my Volvos, a 1989 760 turbo wagon which I just bought, and a 1990 740 turbo wagon that I have owned for several years. The 760 was well maintained and has 202,000 miles. It ran perfectly for the month I have owned it. Then, last night, I drove it to the post office, and turned it off. Five minutes later, I went to leave, and it wouldn’t start. It cranks over, strong battery, good fuel pressure, power to the coil, but no spark. My boyfriend works on cars, but can’t figure out where to look next.
In a stroke of great timing and coincidence, the 740, which has frequently been used for my newspaper delivery business, has begun to sputter and stall after driving fine the first 20-60 minutes. It gets progressively worse until it can barely go a few yards, and finally, fails to start until it has rested for a few hours, when the cycle repeats itself.
I am desperate to get at least one of these cars back on the road ASAP so I don’t lose my job.
