The only way the pump will run is if it has a live 12v dc supply to one side and an earth return to the other.

Most cars have the earth side of the pump grounded down to the chassis so I would go for the fact that you have a short on the loom or a faulty ignition barrel.

An auto electrician would isolate the pump wiring to see where the feed was coming from then repair the fault

Fuel filter possible fuel pump dead battery

C230 2005 will not start


If it fails to turn over then check on battery condition and on battery connections (do full beam headlights stay consistently bright for ten minutes). If Ok then check on wiring to and from starter motor and on condition of starter motor brushes. If turning over can you hear the fuel pump running; whirring sound when key at position prior to 'start'. If no fuel pump check on fuse for pump relay, check on relay, check on voltage at pump. If pump supplied with voltage but not running give it knock to see if you can get some kind of response from it. If completely dead replace pump and filter assembly.

Fuel pump fixed, turns over but still won't start


I don't know much about these but on my daughters 1.0i polo I had to reset the throttle with a computer after disconnecting the battery for a while.
If you are sure you have a spark and fuel getting to the plugs then the fault will lie with timing and fuel mixture.

2001 Ford 4 door was runningg great turned off went inside an hour later tried to start and it wouldn't turn over, also can't shift automatic in neutral. Tried to jump start thought it was dead...


I'm thinking its the battery. Heat kills batteries. You said it wont jump start. That's a dead ringer for a bad battery. It may have enough juice to power some things, but wont run the starter, or the fuel pump, or the ignition(spark). Try a new battery and let me know!

My 1991 BMWi ran out of fuel and now it won't turn over at all


You say it won't turn over. Do you mean that the starter will not crank the engine? Not cranking is totally unrelated to running out of fuel, other than perhaps someone cranked it until the battery was dead after it ran out of fuel. Try a jump start from a known good battery.
If the starter cranks the engine but the car will not start after running out of fuel, my bet is that the fuel pump was nearing the end of its useful life, and running dry as it ran out of fuel was the end of that fuel pump. Fuel pumps are lubricated and cooled by the fuel, so running dry is really hard on them.

Wont start


The fuel pump jump started? The fuel pump relay is in the dashboard relay center. The fuel pump is inside the fuel tank. The pumps do fail entirely nd the fuel pump should make some sound if it's running. The fuel filter is on the firewall on the drivers side. It has a bleeder screw in the top of the bnjo bolt that holds the fuel line onto the filter. Loosening this bolt should release fuel pressure. With the bolt loose try to get the pump running ( knock on the relay, fuel tank, while cranking the engine) if fuel flows the engine should run if you don't have other problems. Low battery will crank the engine but not turn on the fuel pump and or the injection system and even the ingtion system. It may still crank and sound OK. Voltmeter the battery with the engine cranking, Less that 10 volts it's unlikly to start. John

Left my car lights on.. tried to push start it and it wouldn't start then tried to jump start it and it would work for a bit then cut out again after about 20 sec's. my rev counter was not working while...


Dead battery can't be pull started,there's no electricity for spark to ignite the fuel.Put a full charge on the battery and take it to your local auto parts store for a load test.They will tell you if it's bad.Battery could not have enough of a charge to stay running or you could be looking at an alternator problem.Charge the battery and start the car,disconnect the - (negative)post of the battery.Car dies,your alternator is bad.Hope this helps?

1997 Cirrus battery went dead. The car ran fine


These cars are known for having engine related electrical problems that can be difficult to track down. One dead sensor is sufficient to prevent start up .

It is possible that your problem had nothing to do with the jump start or battery replacement.

Without a full diagnosis anyone not able to test the vehicle will be guessing.

One thing I would do is to check your fuse panels for all engine related fuses such as fuel pump, ignition and fuel injection to ensure these fuses are sound.
Check all visible wiring carefully including your battery connections. Carefully disconnect and then re-connect the battery at both terminals.

Your best option is to have the car towed to a reputable repairer that is familiar with these cars so he can run a full check and isolate the problem.

Whether you have blown something in the course of jump starting the car is unknown.

In future, when jump starting these older vehicles always turn the headlights on and do not turn them off again whilst the vehicle is running until after the spare battery used for the jump start has been fully disconnected. Everything else should be off.

2000 Jeep Grand cherokee Laredo wont start. Engine turn over . No noise from fuel pump with ignition on. Replaced fuel pump and filter.Turn ignition on- pump did not run.Jumped the fuel pump at the pump...


sounds alot the the pcm it controls the fuel pump and ign system but the anti theft would keep it from starting because the key has a transponder in it programmed for that vehicle and that would kill all ign if triggered
