94 concorde as stated earlier car wont start. changed fuel pump it pumps when i jumper wired the fuel relay. changed cam sensor changed knock sensor changed coil pack.when turning key car cranks over no power to coil fuel pump etc. fuses and relays under dash and hood are ok

Have someone stand or lie down close to the gas tank when you first turn the key on WITHOUT STARTING IT. They should hear the pump running to build up pressure. If not, check the fuse box under the hood for a blown fuse or bad pump relay.

check see if you getting spark if not.have vechicle code scan could have faulty ECM .faulty camshaft sensor and crankshaft sensor.make sure engine has been tuned up.replace fuel filter change spark plugs and wires. before engine can run need fuel and spark.either one not working car will not crank.

When you say the fuel pump relay is good did you test for power to the relay circuit ?

NO POWER TO FUEL PUMP......CHECK ALL IN LINE WIRING
NOT FIRING... START WITH COIL PACK, DIST CAP ETC...PLUGS/WIRES??????
"HOT WIRE" (DIRECT W/ FUSED JUMPER) TO FUEL .PUMP....NO - GO,,,BAD PUMP

make sure the fuel pump relay is working. just put one in from another place. same size, to see if thats it. or your fuel pump is bad. is it getting spark!

another way to test it
unplug any fuel line you can locate tell a friend to start key one turn only if the line squirts fuel then pump is working and it might need regulator
if not then pump is gone

2.7? Try unhooking the cam sensor? Also if it does start after unplugging the cam sensor, don't drive it. Post back.

the fuel pump relay is on the driver side firewall its a bracket with two relays on it. the relay closes to the fender is the one for the fuel pump. if you want to do a quick test of the relay is to run a jumper wire from orange wire to the grey wire you pump should start working.if it does work then replace the relay. if it doesnt work. run a jumper wire from the battery to the grey wire if the fuel pump still doesnt work replace the fuel pump, however if it does work you have a short in you wires. a good back yard fix for this problem is to run a wire from the battery to the orange wire. hope i didnt confuse you let me know if you need more help.

I CHANGE CAM AND CRANK SENSOR,FUEL PUMP,COMPUTER BRAIN BOX AND COIL PACK STILL GETTING NO FIRE UNLESS I JUMP A FIRE WIRE FROM BATTERY

Change fuel pump relay.And check the fuses
