When you changed the fuel pump, was it not getting any fuel pressure before that ? Is it getting fuel pressure now ? And is it getting spark to the plugs ? If the check engine light does not come on when you turn the key on I would check that fuse first.
If the check engine light is not on when you turn the key on, check the fuses. The fuse for the computer may be blown. If it is you will need to look at the circuit to find the short that blew the fuse.
prob the fuel pump going bad mine was doin the same thing b4 the pump died completely i changed it and its worked ever sence.to check if it is the pump the next time it dosent start have someone turn the key over dont crank the moter but turn it the hole way just b4 it starts to crank wile your lookin under the car and listen for the fuel pump to click if it dosent then thats the prob.
my first guess would fuel pump have some turn the key in the on pos, while u stand buy fuel door must be quit around you you should hear a light humming sound coming from fuel tank area the humming is the fuel pump also check fuel pump relay in under hood fuse panel hope this helps
Was it empty when you parked it? (i.e. did someone drain the tank, and put sugar in it? something like that?)
If not... the fuel filter could be clogged. Check that. Most cars of this age are fuel injected, so the fuel at the fuel filter will be under high pressure. Chiltons manuals usually discuss how to de-pressurize the line if needed. But you probably already dealt with this changing the fuel pump.
Good to hear it's turning over.
After (finding) the filter... check to see if any fuel is making it through the filter. Turn the ignition to "on" and it will likely start the fuel pump and spray fuel everywhere (if you disconnect the filter output.).... besides having a mess, you will know your fuel pump works. (Try attaching a hose from the fuel filter output to a bucket to prevent a mess and possible fire please ).
Can you hear the fuel pump running? Could be a blown fuse for the fuel pump.
If you turn the key to the run position and listen carefully you should hear the fuel pump come on for a few seconds. If not...it's either a bad pump and or relay. Most have a check valve up on the fuel rail of the motor that is used to check fuel pressure with a gauge. If you hear the pump running and still have a no start you need to hook a gauge to this valve to check fuel pressure. Specs for your exact vechilce can be found on-line. If pressure to low could be clogged fuel filter or pressure regulator...if to high then its the regulator. Been down this road before so I gotta say it...make sure you have fuel in the tank ;-)
fuel pump is in tank, have someone listen at the fuel door while key is turned on, should hear it running if not take rubber hammer and tap fuel tank to see if that starts the pump, also check fuses under hood for fuel pump and ecm b fuse, if fuse blown more than likely fuel pump, hope this helps
