can I trace a source of a short circuit in my car's fuel pump wiring with this?

Hi, I have this tool. You can - if the short is somewhere in the cables. You'd then first add the tone signal to the cable before the short, and then follow it using the probe. Once you pass the point in the cable where the short is located, the tone will quickly fade and dissipate. If the short is somewhere inside the pump this tool will not be of help, and you'll be better off using a multimeter measuring ohms whilst disconnecting cables one by one.

Possibly. I would suggest you pull down a copy of the user instructions and also call to discuss your particular use with the product manufacturer.

The label on the pump says 16 amps. I ran a (probably 12 gauge) wire from our house batteries, under the motorhome, to a heavy duty 12 volt outlet in a compartment near the dump valves. I used a 20 amp inline fuse. The fuse has never blown. My guess is the pump would draw a little less than 15 amps.I apologize for being a "nitpicker". More than 15 amps wouldn't be a "short circuit". A circuit breaker should trip.

check to make sure the wires are connected correctly or check to see if you blew the fuse

Not really. Maybe check and make sure they didn't mix up a couple wires that go to your coils. Or if your coils are around 50 to 100k miles old ten they may be going bad

Sorry. I'm an industrial electrician. I know very little about cars without carburetors. My guess would be NO. It is a great test tool , but doesn't have the response time of an oscilloscope.

There is an ECM on the passenger side interior. Right under a kick-plate behind the door. That is what controls the switching. The best way to test is to put it on a diagnostic computer to see where the fault lies. I've had both go bad so it does happen. That ECM sits in a place where water can get at it at times and rust the connector pins among other problems

No. It is powered by the circuit voltage. It will tell if the Hot and Neutral are on the correct terminals.

no manual, you have to look up the the vehicle your working on line. but it will show you is the Fuel pump is pumping gas.

This Product is meant to be used with a remote start and alarm system. It is not meant to fix problems with your vehicle. It sounds like your GM vehicle has the usual problem with the Ignition Cylinder. On a GM car, as the Ignition cylinder turns with the key, the body computer senses the amount of resistance that is built into the Ign. Cyl. in ohms, so the computer can turn the electric fuel pump on, this was built in to prevent theft. On the GM Ign. Cyl., there are 2 small wires that have a little pigtail and plug, what usually happens after many years of turning the Ign. cyl. on and off, one or both of those wires breaks, on the inside, you can not see the break. That is why sometimes it starts for you, sometimes the wire makes the connection, sometimes, not. As you turn the Ign. Cyl., those 2 wires move back and forth, they break after time.

I took my meter and found a wire from the wiring harness that controlled by Ignition Switch .. left side by battery... and spliced a 12 v relay to it... works great .....rj

Yes - with the following IMPORTANT warning!The Positive Lead from the Battery MUST be lifted - disconnected - Then you should be able to trace a single wire by putting one of the Toner Leads on the Frame of the vehicle, and the other lead on one end of the wire to be traced. If you read the Fluke Manual - they describe the single wire tracing mode - in house wiring they suggest one toner lead on the ground wire of unshielded wire.I have used this in 'low-voltage' telephone line tracing, and network cable tracing.Ron

It depends on the car and the software you are using with this code reader, but mainly yes. As least if it did not tell you which O2 sensor is bad it will tell you that an O2 sensor is bad somewhere.

Yes, you could trace any wiring with this as long as you can disconnect the power from it, like your battery in this case.

It blew a fuse in my car at an end on inflating a first tire. I was adding 7psi. this was 30A fuse (2 sockets on this circuit). I returned it because of this event. I didn't want to experiment whether it was a single event or failure of this one inflator, or typical over-current.

I had the same problem after fixing the fuel pump ending up having to fix the fuel injector wiring connector

This is not the problem. It has only one connection and that one only to switch from left to right tank. In the newer models this type of switch has more connections. I think you have a broken wire in the circuit to fuel level sender or a bad ground.
