Fuse for fuel pump on 2001 pontiac sunfire


There are some logical steps need to be taken 1st. Verify if the engine has air, fuel and spark. Fuel can be checked with an inline gauge at the fuel rail. There could be several different things wrong. Bad ECM, fuel pump, injectors, fuel pressure regulator etc. Need to verify spark, this too may have several different problems. Bad ECM again, power/ground circuit faults, coil pack ect.

1999 sunfire will start but stalls after a minute or so. turn key back to on position and can hear fuel pump then can start it again but only runs for a minute then stalls again


Assuming the pump relay is good, it could be the engine computer or something else. The computer needs to see oil pressure or RPM to continue to energize the pump relay. You could jumper the relay to verify.

No power going to my fuel pump relay


If it was an AUDU/VW I would be sure it is your crankshaft position sensor not working. In this instance there is no problem checking that too. Check if you have a spark at the plugs. If ypou don.t have then your fuel pump wont come on.

My 1998 sunfire's horn is not working. I hear clicking when I press on it. Any ideas on what the problem could be?


The clicking if heard under the hood it is the horn relay. So, either the connectors on the horn(s) are loose or the horn(s) are bad.

1999 range rover se changed fuel pump, truck still wont start, relays and fues look good.


why you have replaced the Fuel pump? who advised you to do so?
be guided as follow 1. on the Engine Side on the top there is a fuel rail for the injectors. turn the ign. key to the second position (on) and check the valve located on the fuel rail if fuel is coming pressurized and still won't work. then open on of the spark plugs wires and check if spark is there. (Be Careful doing that). if no spark then is there any message comes up on the Dash? if not messages then you can check the Crank Sensor if no current being generated from the ign. coils.

No power to fuel pump 1999 sunfire


Check the wiring at the fuel pump assembly for corrosion, if the wires look ok, i would then move to the Crank and cam shaft sensors. if these sensors are not in good condition , it will cuase these actions.

if everythign checks out ok with the sensors, this will confirm a serious PCM issue.

96 windstar, no power to fuel pump


The power to the fuel pump occurs for only a short time when key is on,engine off. This is to prime the fuel line. Power resumes during cranking and running. Was the power to the pump checked during these cycles or checked with key on only? Power may be present and fuel pump is not reacting. Hope this helps..
