P0230 fault - citroen xsara picasso 2001 2.0HDI - not fuel pump or relay changed - intermittent cutting out on car - can drive 30 / 5 / 15 miles before this occurs


code p 0230 refers to fuel pump relay---circuit malfunction===causes --wiring---fuel pump relay-- ECM
check wiring for bad connections
replace the ECM with a known good unit as it may be breaking down electronically in the circuit that controls the pump relay
Check the pressure regulator as well as it reports to the ECM to shut off the pump relay when the fuel pressure is reached and not being used

Why does my ECM-I fuse keeps blowing?


Did you check the crank sensor wire, it may be hitting the hot exhaust. does the wire going to fuel pump have a problem and is shorting out. ECM 1 ..... then there are 5 components that this fuse feeds
1-crank sensor
2- all injectors
3- ECM
4- electronic ignition control module
5- ignition coil - check for a bad wire in these areas. Hope this helps.

Where is ecm on 95 gmc jimmy


The ECM on the jimmy, is located on the passenger side fender well by the overflow tank. But before replace the ECM, inspect the fuel pump and fuel pump relay. The ECM sends power to the fuel pump relay and if the relay has gone bad will cause the fuse to blow which will kill the the power to the ECM, in turn kill the electrical power to the ignition system.

Start by removing the fuel pump relay and swap it with another relay and see if the fuse will blow again, if is does. Disconnect the fuel sending unit wire harness at the frame and see if the fuse blows again, if the fuse stays good. Chances are your fuel pump has gone bad or the fuel filter is dirty/clogged causing your fuel pump to draw more amp and will need to be replaced or the wire harness from the frame to the sending unit has a short which is common on older Jimmy's.

Here is a link to the electrical harness throughout the Jimmy.

Fuel pump relay secondary circuit - high voltage


Here is the definition for the code.
Test procedures are a little different depending on the make and model.

P0232 Description The Engine Control Module (ECM) provides ignition positive voltage to the coil side of the fuel pump relay. When the ignition switch is first turned ON, the ECM energizes the fuel pump relay, which applies power to the fuel pump. The ECM enables the fuel pump relay as long as the engine is cranking or running, and crankshaft reference pulses are received. If no crankshaft reference pulses are received, the ECM de-energizes the fuel pump relay after 2 seconds. The ECM monitors the voltage on the fuel pump relay control circuit.

After turning on ignition switch to try to start car my fuel pump cut off


Possible there is an error in the ECM and must be checked. Please check all the input sensor parameters to the ECM, check the fuel condition, fuel filter and also the ignition system. Check the power to the fuel pump , fuel pump relay. Also if there is a fault in the fuel pump it can cut off.
Check the fuel pump pressure- calibration to be checked.

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

Underhood fuse block swap out relay #7 thats the ECM relay.
Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.
