|
|
So, I was on my way home from work, and my square back just stopped running. No scarry noises, just stopped. I have plenty of gas. Got it towed home and started to do some checking. Its getting gas. THe coild is sending spark, but the damm thing won't start. It turns over, the battery is fine, just won't catch.
Thanks,,

Three things needed for an engine to run. compression, fuel, ignition.
One of these is missing.
You say you have fuel, but do you have fuel pressure?? It is Fuel Injected isn't it?? Are the injectors working?? Are the trigger points connected?? Is the fuel pump running??
Please give us more information. _________________ Society is like stew. If you don't keep it stirred up, you end up with a lot of scum on the top!--Edward Abbey

Are you sure the fuel pump is working. You will hear it when you turn the key. It will hum for a second. The fuel pump relay will click as will the main relay but the fuel pump makes a hum. Of course that is if the Fuel injection is still in place.

It does sound like the fuel pump is humming. |

As Russ said, fuel, ignition and compression. If you have fuel, check the dizzy, points gap, dizzy grounded, rotor cap in place, coil wire in place, trigger points connection in place on the dizzy? Plug wires all on? Give us more information. did the car just quit and not restart? That sounds like fuel pump to me. _________________ Ho'oponopono |

Being a '71 or newer, leave the key turned on, and go to the engine compartment. Slowly open the throttle by hand. You should hear a series of clicks. 20 to be exact. This says that the ECU has power, and the injectors are working. _________________ Society is like stew. If you don't keep it stirred up, you end up with a lot of scum on the top!--Edward Abbey

So I tried pulling the throttle back with the key on, and there was clicking. What is the ECU? |

Also, let me add this little nugget of info. (gawd I feel like on of those jackasses calling into carTalk) So the car has had a an issue of everyonce in awhile running rough when she first starts. If I drive the car for say ten minutes, then turn it off for ten, when I start again, its fine.
I have no idea if this is related. My focus in the morningis going to be on the distributor. I do not seem to be getting anything out of the spark plug wires when I did Muirs test on them. |

Check the resistance of the plug wires, about 1000 ohms each. Check the resistance of the rotor, about 1500-3000 ohms. Should he check the small ground wire on the distributor breaker plate Anne??? _________________ Society is like stew.

Yes (said very sheepishly) That little ground wire can cause some rough running and difficult starting. _________________ Ho'oponopono |

Oh yes, ground wires . . . Annie, I feel your pain (and shame).
Always always look at them suckers. They'll kill your car faster than anything . . . |

There is a small braided on on the distributor breaker plate near the ignition points. Not the one that is actually part of the points, but another one.
There are about 3 or 4 grounds on the block under the right/pass. side of the intake manifold.
You say you hear the pump run, so that one is probably good, up by the gas tank. And the one for the FI is probably good, because you hear the injectors click.
Be sure you are getting spark, and be sure you have fuel pressure. _________________ Society is like stew. If you don't keep it stirred up, you end up with a lot of scum on the top!--Edward Abbey

SO I worked on it all day. Found a gas leak replaced that. Tried a different coil, Then I noticed that there is no vacuum line onthe dizzy. I have to recharge the battery before I can do any other testing. Will the vacuum line from the dizzy cause it not to start?
Anyone in the Seattle area want to make a couple of bucks and look at this thing before I junk her? |

No, the vacuum line off will not stop it from starting. What part of the equation are you missing. fuel, spark, or compression?? _________________ Society is like stew. If you don't keep it stirred up, you end up with a lot of scum on the top!--Edward Abbey
