Changed fuel tanks, getting P0183 OBD code now.

ANSWER : The switch you are referring to is vended with the required electrical and fuel schematic (I just looked in the box) that answers your installation question. If you want an advance view, here is a link as well. Yes, you need a return line and just refer to the aforementioned link. If you are retrofitting back to OEM, I strongly encourage you to buy the original Factory Service Manual (FSM). There are lots of details attending this system and obviously it is difficult to recount it all here. The FSM will make your life much easier and you can then make sure your installation is perfect. Alternatively, YourMechanic can dispatch a certified mechanic and perform the whole retrofit and check out if you desire. Just request and schedule a generic service such as fuel pump service and the mechanic will come to your location and estimate the parts and labor required. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : The two tanks are designed to work together and so BOTH pumps must be functioning and, as well, the related fuel system supply code, the Code P0232 that has set has to be resolved. P0232 means that the fuel pump relay is stuck on, keeping power supplied to the fuel pump even after the ignition has been turned off although another possibility is the fuel pump secondary power circuit has a short to battery voltage. The factory service manual (FSM) specifies a very lengthy diagnostic (because you have separate tanks). If you do not have the FSM, your best bet is to request a fuel pump diagnostic – dual tanks and let a certified mechanic get to the bottom of this. With regard to the other code, P0704, that code will set if the clutch switch is defective, there is worn clutch pedal lever or clutch lever bushing, shorted or open wiring and/or connectors in the clutch switch circuit, a blown fuse or burnt fusible link and/or, rarely, a faulty PCM or programming error. If you request the pump diagnostic the responding certified mechanic will get this taken care of for you.

ANSWER : Hello, thanks for writing in. Code P0183 is the code for a fuel temperature sensor A circuit, high input. This code is set off when the computer detects that the sensor is out of range. In the particular instance the sensor is reading high, which could be caused by a bad sensor, wiring, or computer. You mention that the fuel tank had a spot for another connector. It may be possible that that connector is for the fuel temperature circuit, and is throwing the code because it is disconnected. I would double check to see that everything is plugged in correctly. If it is, then I would check the fuel temperature sensor and wiring. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this code for you, and make or suggest any repairs as needed.

ANSWER : There could be a few things contributing to your problem. You are correct that clogged or sticking fuel injectors and possibly the fuel pressure regulator could be faulty. A plugged catalytic converter can also cause the vehicle to bog down. A failing throttle position sensor can cause the symptoms you describe as well. I suggest having a certified technician, like one from YourMechanic.com, do a few tests to determine the exact cause of your starting concern.

ANSWER : You need to look at the theft light on dash to make sure it comes on and goes off when you turn the key to the on position. If light comes on and stays on then your theft system is causing the fuel pump to not be engaged. I recommend you check the theft system and then scan the computer for theft system codes. You may need to reprogram the keys to work or you have an bad sensor for the ignition key in the steering column.

ANSWER : Hi there. I would recommend checking the fuel pump fuses to be sure the fuel pump is getting power to it. Also, check the ground wire to the fuel pump as well as this is a common issue when they become loose or burnt or shorted. If the pump is working, check to be sure the pump is moving the fuel to the throttle body. If this is not working, you may have an issue related to the power to the injectors. I would recommend having an expert from YourMechanic come to your home to diagnose the related electrical circuits to pinpoint the problems.

ANSWER : Hi there – I suspect you have weak power getting to the fuel pump. I would first check the voltage coming out of the fuel pump relay. If the contacts in the relay are burned, you will not get reliable current flow to the pump. Check the fuel pump ground as well (voltage drop across the ground, not just continuity). I recommend a fuel system inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

ANSWER : If the exhaust smells like gasoline, the fuel mixture is either way too rich or you have a weak ignition system that is not burning the fuel efficiently. You can pull spark plugs out to check them and if they are wet or black they may be fouled and this can cause very rough running, misfires and stalling. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer inspection of the vehicle in order to run a few tests and offer a more personal diagnosis of your stalling and drivability concerns.
