Where is the fuse for a fuel pump on my 2003 dodge diesel 2500 located?

there is no fuse at all for that model. It is controlled by the ECM. you need to replace the ecm

The ECM is located on the left side of the engine block right behind the fuel injection pump remove the connector from the ECM and check the terminals very carefully sometimes you'll find corroded terminals or broken wires causing the same problem. hope this help out.

Car cranks but will not start

first thing take the 120 amp fuse out and throw it away
the 100 amp fuse was installed originally to protect the wiring and other related parts
next by connecting to the wrong terminals there is a power surge that can damage the electronics in the ECM unit and alternator
removing a battery for a charge can corrupt the immobiliser system
I would suggest that you use a scanner to read any fault codes that may be stopping the engine and then reset the CPU program in the ECM to reset the immobiliser

I have a 94 Buick centry and the ecm fuse keeps blowing out. New battery and starter. What would cause it to happen

A short in the ECM , does it blow the fuse right away ? or does the vehicle start then it blows the fuse ?A short in the wiring going to the ECM could do it also ! Disconnect the connector at the ECM Pull the fuse an check the wire with a ohm meter ! starter has nothing to do with, has a short to ground somewhere on that ECM power feed circuit .You need to find a wiring diagram for that circuit. Connector 2 black 24 pin connector , A-2 pink wire . first you need to find correct side of the fuse pin without power , with volt meter , one side will battery voltage ,you don't want that one ! put black lead to ground an the other to the wire an see if there is continuity. Hope this isn't to long winded an I hope it helps !

Can I dsiable abs brakes 2002 4runner

You can remove the abs pump fuse & see what

The question is why?

You have conventional brakes until a wheel slips

I would command the hcu unit open & then remove the fuse

When you go to inspection, you fail, as the ecu/pcm/ecm, etc
won't be ready,it will be looking to run a test on abs every time
you start the engine or turn key on

Where is the ecm fuse on a dodge 2001 stratus

Hi Billie, I'm glad to help!

Billie, what your looking for is the Ignition fuse, BUT an easier way would be simply unhook the battery negative cable then do what ever work you plan to do and then install the cable. Hope this helps and have an awesome day Billie.

I own a 2004 Isuzu Rodeo 3.2L V6 2WD. On saturday it died on me. at first i thought it might be the fuel pump because the engine turned over but wouldn't engage. Gas level was good as was the battery. ...

my problem was electrical, removing the batt (neg. terminal) for a few seconds resets the Engine Control Module (ECM) which operates the full pump relay, there should be a fuse in the relay box in under the hood labeled ECM or ECU. Pulling that fuse for 10 secs. or so also resets the ECM, try this and if it immediately works I suggest to drive it locally until it will not start again and repeat the removal of the ECM fuse. If this work out I suggest that you ECM is receiving a sensor signal to shut down the pump relay so I've been told, is the check engine lite on
