My husband turned off our 2000 silhouette at a school to get out and when he came back it wont start it tries to but just wont we changed the fuel filter and the fuel pump relay and i really dont want to...


If you dont know what the fuel pressure is, dont guess. Buy a $20 fuel pressure gauge and hook it to the fuel injector rail and see what fuel pressure you have 35-40 psi. Do you hear the fuel pump run? it should run for 2 seconds when you turn the key on. Do this first,Sometimes....... you can get to pump to run a while longer if you rap on th tank while someone is cranking, that may get it to run long enough to get to a repair shop.

Went to a store came back out would not start but strong battery,im tinking fuel pump dont know alot about car only had it a week


stand outside your van,reach in the window and turn your key over,but not to the start position. you should hear a whirring sound from the rear of the van and it should last about 2-3 sec. this will be your fuel pump powering up. if you dont hear it,then you have a bad fuel pump. Dodge Caravans from 96-01 are VERY bad about eating fuel pumps. if the pump is fine,have someone try to start it while you look under hood and see if injectors are spraying fuel. if the pump is good,and you have no spray from the injector,then you have a clogged fuel filter which will need replaced.

How do I tell if my problem is the fuel pump or fuel pump regulator? I don't hear the fuel pump when I turn on the ignition


Remove the fuel line from the fuel filter inlet side, it should be marked with an arrow, but either hose will give you the same result. NOTE: Be careful though as the fuel is under pressure so remove the hose slowly and try to relieve the pressure before you pull the hose right off.Make sure is not HOT.

Then put the hose you have taken off into a bottle and turn the key to the on position first, if you see fuel coming out then the pump is ok. If no fuel then turn the key to the starting position and crank the engine over for a couple of seconds. If no fuel your fuel pump is faulty. The fuel pressure regulator should only be tested with a fuel pressure gauge. But see how you get on with the fuel pump first. Good luck, let me know how you get on.

My car car is turning over but not cranking up.i dont believe its getting gasn i drove it from houston then to fort worth. and now not working


if you have an electronic fuel pump, turn the key all the way until the instrument cluster lights up, just don't turn on the car, now listen carefully when you do this, if your fuel pump is ok, you will hear a low whinning noise coming from the rear of the vehicle(gas tank area). this is the fuel pump priming itself, this means your fuel pump is ok. Now, if you dont hear this, you might have a bad fuel pump relay. replace with another relay and see if the car turns on. if you still don't hear the fuel pump turning on, then you might have a bad fuel pump. remember, once you use electronic parts you can't return them(the relay).

Car will turn over but not start


Sounds like its the fuel pump. Locate the line going into the engine which carrys the gas, insert an electrical fuel pump.

Fuel pump may be getting weak. If pressure is not high enough the injectors wont open.
