If the fuse blows, the last injector you plugged in is shorted. The information contained on this site is presented for informational purposes only. Both values should be about the same. If all are missing, check for continuity to ground on the voltage circuit by using a test light connected to positive battery and probe each voltage feed. So if you have lost voltage to all the injectors, replace the blown fuse and plug each injector in, one by one. If a spark jumps across spark tester, go to step 33. If test light does not illuminate, go to step 26.
Remember that a fuel injector can work properly when cold but go open when hot, or vice versa. If a spark does not jump across spark tester, go to step 34. As soon I reached the nearest part of the harness to the pcm the noid stayed on. Now I know for a fact that when my ignition is on, the 8 injector work like all others. After repairs, go to step 43. If connections and terminals are okay, go to step 16.
If engine does not start, or starts and stalls, go to step 2. Other injector circuit fault codes may set as well. If fuse is open, go to step 20. If you have any doubt as to repairs on your vehicle, please contact your technician. If the injector is open or the resistance is higher or lower than the spec, replace the fuel injector. Ensure proper starting procedure is being used. If the noid light flashes rapidly then suspect the injector.

If test light flashes, go to step 38. Now I know where to start looking for the shorted wire. Check and replace as necessary. This refers to too high or too low voltage or resistance drop at the injectors. If the injector tests out, the problem is likely an intermittent wiring problem.
If test light flashes at each harness connector, go to next step. Using scan tool, command fuel pump relay on. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. While checking for the short to ground, feel free to move the harness around while watching your meter. If test light illuminates, go to step 17.
I erased the code with my android and things went back to normal…so I thought. Then, check the wiring harness and look for signs of damages, especially the fuel injectors. Using a test light connected to battery positive, probe fuel pump ground circuit at fuel pump harness connector body side. It worked perfect for the 3 days test. After repairs, go to step 43. How serious is the P0200 code? Care should be taken with P0200, as severe drivability concerns and potential for unsafe vehicle operation can be present with the vehicle.
Other injector circuit fault codes may set as well. All locked or wrong year. Repair short to ground in fuel pump relay ignition feed circuit. Using a test light connected to ground, probe fuel pump feed circuit at fuel pump harness connector body side. Not sure if you have rubber fuel lines or plastic ones. Electronic fuel injection has been implemented in cars since the 1980s.
If test light does not illuminate, go to step 22. So the swap is done. Specifications on the definition, troubleshooting and repair of the error vary from one make or model to another. If spark plugs are okay, check for water in fuel system. . If fuel pump operates, go to next step. This tells them under what conditions, such as vehicle speed, operating temperature, and engine load, the code occurred under.
A fuel injector Courtesy: waynesgarage. This may help with injector issues in some cases. What does the code mean? After repairs, go to step 25. Once the truck is running 8 stays wide open!!! If the noid light flashes when cranking the engine, the control circuit is functioning properly. If ground circuit is okay, go to next step.
Other injector circuit fault codes may set as well. Look up the other , please use the search box. So I start tuning my idle. The currently selected is for the Toyota makes. After repairs, go to step 25. The seriousness of this code can range from just the Check Engine Light being present, to the vehicle running poorly and having a lack of power.
