I'm at a loss. My husband is out of town and my disco is acting weird (please don't think I'm surprised by this). I was at a stop light and the engine cut off. I tried several times to start it back up and it would turn over and cut off right away. I turned the radio and air off, took the key out of the ignition for a minute and tried again. This time it started right up and stayed on and has continued to do fine. Good thing, too. An ambulance was coming up behind the traffic jam I had created. So my dilemma is this: do I take it to the stealer, oops, dealer, or is this a common thing and I should just consider myself lucky I didn't get a ticket for obstructing the passing of an ambulance? I'm a nurse for God's sake, not a mechanic, Jim. Help! - Mendy |

Hmm , I would be wondering about the fuel pump...Might have issues with the harness , a relay , or the pump itself

beam your hubby home and make him deal with it scotty
could be alot of things ,a bad/dirty stepper motor will often cause AC/ to overtake idle and kill it. turn off the AC and it works fine... |

Sorry, I can't offer any help, but a nurse named Mendy, I find that quite entertaining.

had a problem with my '95 cutting out, not starting, then starting later on without touching anything. as mentioned, turned out to be the fuel pump and fuel pump wiring harness. |

Low voltage drop too many amps used ? She stated it ran fine after she cut all the useless stuff off
Never seen it on Disco but could the alternator not be putting out enough amps and is there a priority on power distribution |

Another stupid question, where is the fuel pump located and how do you test it.
thanks agian. |

Fuel pump is INSIDE the tank, under rear cargo area. Not trivial to get at. Could also be bad contact at ign switch, if it dies as you relax the switch from START to RUN position. This one easy to fix, if it is the problem.

How to check fuel pump:
1. Get a fuel pressure tester. Sears carries these for about $40.
2. Start car & then remove the fuel pump fuse from the fuse block behind the battery. This will depressurize the fuel system.
3. Hook up Pressure tester to the fuel rail. There is a Schreader valve(looks like a bicycle tire valve) on the fuel rail.
4. Reinstall fuel pump fuse.
5. Turn the ignition on, but don't try to start the car.
6. Read the pressure gauge. The correct pressure should be 34-37psi. If its lower, there's a problem in the fuel system. It could be the pump or wiring which isn't allowing the pump to work properly.
7. Start the engine. The pressure gauge should read 30psi. If not, again there's a problem in the system.
8. Press the button on the pressure gauge. This will depressurize the fuel rail so that you can remove the gauge without spraying fuel.
9. Remove the tester.
Hopefully this makes sense. Be sure to read the instructions that come with the gauge, in case I've forgot something.
Here's a easy way to check the fuel pump. Turn the ignition on, but don't try to start the engine. Wait a few seconds. Turn ignition off again. Repeat the process a few times. Then try to start the car. If makes a difference in starting the car, there's probably a problem with the pump. What's happening is that each time you turn the key, the pump progressively builds pressure, making the car start.
Hope this helps. |
