93 chrysler t&c awd changed fuel pump and filter, van ran fine again for about 2 months now won't start and don't hear the fuel pump. changed the oil pressure sending unit and still won


fuel pick-up in tank is blocked it has a sock over the end as a gross filter to keep out any big junk from getting sucked into the pump and causing damage to it. the sock can get so plugged up that no fuel will flow, causing the pump to run for a short time then with no fuel flow to cool it it trips the safety and shuts off

1991 f-159 4.9l cranks but won't start fuel pumps in both tanks loud


fuel pump should only run for about 15 seconds when u first turn the key on now you should check to see if the fuel filter is clogged or your sending unit might be bad on the fuel pump itself

My 91 blazer (Jimmy) just quit running. Looks like getting gas. Just turns over and over. Won't start. Just instantly WTF?!


What do you mean it looks like its getting gas ? Try removeing the fuel filter its an in line filter located on the frame rail under the drivers door . Then put a plastic soda bottle on the line that is comeing from the gas tank and turn the key to run for 5 seconds . If you don't get at least 3 to 4 ounces of fuel then your fuel pump is bad . Or its the relay in the glove box or its the oil pressure sending uint . Have you been haveing problems with the oil pressure gauge or dose it start hard a long cranking time . Long cranking is the relay oil pressure problems is the sending unit but it is a back up power supply for the fuel pump . If the filter is clogged the pump is probably shot you could try replaceing the filter but that pump olny last 10 years at best it just depends if its been replaced at one time witch may be likely seenig its 20 years old the new ones were better a lot of upgrades on them check it out i can't do it for you olny you can do it good luck

Fuel pump wont start is the fuel pump in the tank on a 1996 gmc sierra long box 2 wheel drive 4.3 v6


Yes it is and its no fun to replace there are to many other issues with things like fuel lines tank strape the filler neck and the tank it self . These are mostly rust problems . And the pump it self has wireing issues from the harnest the wire is not a resistance wire and tends to over heat casueing a connection problem at the connecter at the pump the new pump will have upgrades that will solve this problem and some others interinaly in the pump however you will need to cut the wireing harnest to attach to new connecter to the pump its not the same and won't just plug in. What you should look at first is the fuel filter its inline under the drivers door running along the frame rail replace it . Then check the fuel relay that should be inside the glove box behind a panel thats marked relay center or relays it will be the one on the far left if you are faceing it . The other thing you could try would be the oil pressure sending unit. The way your fuel system works is it runs on a split curicut i beleive its fuse #4 that powers the relay but it also gose to the oil pressure sending unit witch goes to the fuel pump as well in case the relay goes when your on the highway you won't lose power to the fuel pump its a saftey thing dosn't make a lot of sence to me but thats how it works . If the relay is bad then it will start however it will take a long cranking time to build up enough oil pressure to trip the switch in the oil pressure sending unit to send voltage to the fuel pump. I can't candy coat this the most likely thing is the fuel pump they normaly last 10 years on this vehicle if your lucky . Good luck with it

2004 z71 tahoe when the gas gauge is at a quarter of a tank it won't crank. It acts like it is empty with gas.


Check your fuel filter if it needs replacement. Empty it out then connect it back. Try to start it again. Inspect the fuel filter if it filled with gasoline. Check if there is noise at the fuel tank to check if the pump is working. If it did not, inspect the fuse for your fuel pump and the relay. If both are good you may connect the fuel pump directly to the battery to see if it works. It may be a bad wiring.

REplaced fuel pump still won,t start when its cold it starts right up when its hot the only way it starts when cold is relieve pressure from line 1997 chevey pu . 305 .


Check your fuel pump relay Alot of chevy systems back up the fuel pump power supply through the oil pressure sending unit . So even if the relay is NG the vehicle will still start and run because the oil pressure sending unit is feeding the pump . It also could be a combination of bolth a bad relay and the O P sending unit it needs to build up enough engine pressure to trip the switch inside the sender to send voltage to the fuel pump and it would do this much better if it was cold the oil is thicker

Fuel pump needs to be replaces on 2000 Chevrolet suburban, do I also need a new filter, relay and induction?


Do you know for sure that the fuel pump failed or do you have a bad relay? If the fuel pump relay is good no you don't need to replace it. The fuel pump unit comes with the sending unit and a sock filter. I would replace the inline fuel filter when you replace the pump. In line fuel filters need to be replaced every 36000 miles. If that filter starts to plug up it makes the pump work harder which leads to premature failure.
