Q: I also checked the fuses but still no power to the fuel pump and ideas what it might be?: did you check the pump before fitting it, if not get some cable and go from battery to relay and see if the pump runs,if not check by placing temporary wires from pump relay to the pump and trying Again,if still not working temp cable from battery to pump relay then from pump relay to the pump if it works its a short circuit in the cars wiring loom,if it doesn't work then its the relay or pump, if you checked the pump earlier then its the relay at fault,also check the earths (grounding cables) if these are loose of broken then no return means no power,,just to be sure try a fuse that's working another component,of the same rating,in other words just swop the fuses over if they are same rating, and try again,hope this helps and be careful fuel pumps and fuel and sparks can cause fires

Q: I asked how to fix it, but was just told the same thing everyone else said, go to a mechanic and let them do it. I would like everyone to know write now that is my car, and I intend on learning everything I can about it, secondly I'm broke, and thirdly, i am a very poor grammarist.lol but seriously I would really like to know what this is.: uuuuhhhhhhhhhhhhhhhhh.what!!!

Q: I want to add a circuit to my car to hardwire my gps and radar, and to run my rally lights.I have 10 gauge leads with a 30a fuse. I have 3 spst switches to run each. I have the appropraite fuses for each component.so to get to the point, i need to know how, if possible, to wire them in series so the voltage going to each is the same. This is my first time messing wiith electronics, and do i need to add any relays or capacitors?Thanks,Ben: the voltages in a series circuit are not the same the current is. you need a parleel circuit

Q: Both the windows and the interior light all quit simultaniously any ideas: Most likely a fuse

Q: helloI was installing a GPS tracker in ford Mondeo so i needed 12+ volt from the car. and I take one from driver side under the plastic that' need to the driver knee. there I found many wires and I found red wire I took the 12v+ from it. but by mistaken that wire touched the car ground and now there's no electricity on it I've checked all fuses under the glove box and all fuses near to the engine and non of them was burned out please what should i do: There must be a blown fuse. The purpose of a fuse is to break the connection if the circuit becomes overloaded, this prevents electrical fires, and other dangerous situations. Blown fuses are not obvious if you just glance at the fuse box, you need to remove them in order to see the conductor. I would look at a wiring diagram, find the components on the diagram that are not working, and trace them back to the fuse number and location. This problem can only be a blown fuse or fuseable link.

Q: i recently got my battery replaced because it wasnt holding charge. when it came out of the shop, the clock, power mirrors, and floodlights arent running. everything else seems fine, and i checked the fuses, all are intact. There were no problems with those 3 components before the battery was replaced. Any Ideas to fix this? thanks: Did you check the fuse block in the engine compartment. There may be a fuse or relay there that is bad. There may be a spare relay in the box. If this fails, I would go back to the shop and explain it to them. They may have disconnected something and didn't get it hooked back up. Hope this helps and good luck

Q: I own a 1999 Chevy Malibu with a v6 engine. I had a problem before where the car had trouble maintaing stability and dropped way below .5 on the RPM. I fixed the problem but that presented another problem. The Air conditioning and windows won't start at most times. I checked the heat gage and found that whenever it reached past halfway on the heat meter, the problem presented itself again. this led me to believe that it is an electrical problem. the thing is, if the cooling fans aren't working at the same time the A/C and/or the windows, then what is the source of the problem? my question is what is a(n) component(s) that is linked to the windows, A/C, and the cooling fans besides the battery? Please help! THX!: fuse box and relays and power source not battery but wires to the battery, switch's and or sensors, but they are odd things not work at the same time

Q: As stated, I'm going to add an extra CL in my fuse box for an accessory. Would it hurt anything to just add it to the lower gold bolt that already has a ground attached? I'd consider the empty one but I can't get my hand behind it and don't want to not be able to tighten in back up. Thanks for any advice, sorry for the novice question, I'm fairly new to working in my car.: Be careful, a cigarette lighter is a very high amperage draw device. The single existing fuse is only designed for one lighter, so you should consider running a dedicated line from the battery, fuse protected, to your new lighter. However, if you only plan on using the lighter socket for small current draw purposes, like a cell phone charger, then you could be okay tapping into an existing line. As for ground, any existing ground should be okay, as well as adding a new ground to a metal frame or body component.

Q: i checked the fuses, i had similar problems when i tried to install a stereo deck myself. Also my srs lights are on and my window does not open.: time for another car friend. don't mess with this as it is old. face it jap cars don't last forever. u no n japan they don't rebuild anything? everything is replaced every 100,000 km which is 66000 miles. ur car isn't designed to last. that is why every jap car in a wreck is totalled. the jap car co's make more money selling u a new car. so but another jap car. I don't want to catch u riding n a real car, like a 57 chevy or 67 mustang. I will pop u n tha haid an take it from ya.

Q: from a circuit board, is this a resistor or a fuse?: Use a volt/ohm meter to test the fuse. Connect leads to each side of the fuse. With power off, measure ohms. Anything other than zero, you need to replace the fuse. or With power on, measure volts. Anything other than zero, you need to replace the fuse.
