The fuel pump on many vehicles has a switch incorperated into the air flow sensor. This is to stop any chance of flooding....If the air flow has a gate try pushing it open a few milimeters and see what happens or if not, connect everything as is required and crank the engine to check and find out if the power is there when doing so....Let me know what happens and then if you're still in problems we'll go further....Regards Johngee

Replaced the fuel pump and filter on a 2001 pontiac grand am se. car wont start is there anything else or filter keeping the gas from going to the engine?


dont know if I can help but make sure the fuel pump comes on for a few seconds when you turn the ignition on if not check the relay under the hood you may need someone to help with this there are 4 terminals when you pull the relay out one will have power all the time with the key on another one will have power for a few seconds when you first turn the ignition on if you have power there and the fuel pump dosent run at all the relay may be bad you can also check the connection by the fuel tank for power when you turn the ignition on also I just put a fuel pump in my sons 2000 grand am and it did not start after I put the pump in but I could hear the pump running but we had only put a couple of gallons of gas in so I put another 3 gallons of gas in and it started I also just put a pump in my daughters 2001 grand am and it started right away but I had put 5 gallons of gas in right away You can also see if there is fuel pressure at the fuel rail on the right side or passenger side of the engine there is a connection to check fuel pressure you can take the cap off and use a screwdriver to push the valvestem in to see if there is fuel there and any pressure. if you have power to the fuel pump and plenty of gas and the pump wont run try hitting the bottom of the fuel tank under the fuel pump with a ribber hammer

OK I HAVE REPLACED MY FUEL PUMP IN MY 2003 PONTIAC GRAND AM SE, THE FUEL SENDING UINT IS WORKING BUT THE PUMP IS NOT WORKING ,I HAVE CHECKED THE FUEL RAIL AND HAVE NO PRESSURE AND I HAVE ALREADY CHANGED...


O.K. this is going to be long but stick with me.
The gray wire that goes to the plug at the sending unit is the one to run the pump. We need to get power to this wire. This wire runs to the fuel pump relay. The relay has 4 pins one is the gray wire-one is the 15 amp power for the pump that has battery voltage with the key in the run and start position. one is ground and one is the relay trigger from the ecm. Pull the relay and look real close on the bottom side of it by the pins there will be numbers 30,85,86,87. 85 and 86 control the relay 30 is the power from the fuse and 87 is the gray wire going to your fuel pump. If you use a test light and see if it lights up between pin 85 and 86 when you first turn on the key (should come on for 5 seconds or so). If not we have a problem on the computer side. If so go to #2 below. If not ground test light and try 85 then 86 if it lights up on one of them when you first turn on key the other post (of 85 or 86) has a bad ground.
#2 So we now know the relay circuit is good Turn key on and check for voltage between post 30 and ground. if there is voltage then run a jumper wire from battery voltage through a 15 amp fuse to post 87 if the pump comes on its the relay if it stays off then there is a open in the circuit from the relay to the pump. don't forget to check for a good connection where the wires go into the plastic on the top of the sending unit. reply if I typed to fast and I can walk you through any step you have problems with.
Good Luck and God Bless

Truck will not start, has fire. relay ok. no trouble codes.


when you turn the key in 'on' position, do you hear the fuel pump hum? check under hood in black box,,fuses,,and relays. for bad fuse or fuel pump relay bad. try bumping fuel tank with something hard to see if fuel pump will engauge with key on. maybe bad pump. have you had off road? look for pulled plug from fuel pump underneath near gas tank.have you bent or damaged your igbition key somehow? the key sends a signal to your cars computer to engauge the pump and crankshaft sensor.but if you do have fire,,,it's a fuel problem, so you are on the right track. if nothing i've said helps, check for a bad fuel pressure regulator.hope this helps and thank you for choosing fixya.com!!

Car starts then dies and will not start again


Sounds like fuel system issue. Possible fuel pump, fuel pump relay, or cam/crank sensor. I hope this helps!

Fuel pump fuse located on pontiac grand prix 2001


in the engine compartment near the battery you should see a flat plastic cover with tabs on each end... remove that and there are fuses and relays under it. the fuel relay should be there.
