Car Wont Move
I just went to move my car and the engine is running very weird. It's almost like it is misfiring I think. When I press the throttle it does not respond at all. And there is a high pitch ringing coming from the ignition box on the left side of the engine.
May just be a coincidence, but before this happened I had the engine fuse box open and moved around some wires. Any ideas?

Probably not a coincidence.

I just tried playing with the CDI wire harness to see if maybe there was a bad connnection. It didn't change anything.
The car starts right up with no problem. But then dies shortly after. The throttle does not seem to do anything. The engine also sounds different, like it's struggling.

First thing I would do would be to check all the throttle linkages. I'm not too familiar with SC's, but on my 72 you can trace the entire linkage from the gas pedal all the way to the carb bodies - it's just several pieces of metal connected together. Embarrassing but true: I was at the track last year and had a tech look over my ignition system to see why I was getting very little throttle response. Just by chance I heard something rattling under the gas pedal and found that the linkage had come off the back of the pedal. Oops...
After that, search here for info and preferably pics of the wiring for the CD box and fuse panel and make sure you've got everything hooked up right. It sounds like it's a pretty simple problem to fix, if you think you caused it in fiddling with the wires.

did you check the fuses on the fuse box?
Check connections. Broken solder joint? Check grounds I'd look at the fuse box. You said it ran fine before you moved the wires; after, it won't run. Look there first. Odds are it's not a coincidence. Throttle linkages is not close to the box on an SC. Last edited by tcar; 09-02-2008 at 10:32 AM.. |

I didn't really move any wires...that was a bad expression....more like touched them. So I was thinking there was a bad connection somewhere that I made worse when I touched them. But I tried playing around with them last night, but it didn't change anything.

Just brushing wires with your hand won't make a bad connection completely fail. Consider the vibration of the engine running at 4000 rpm - THAT will make a bad connection completely fail.
I suppose the possibilities does indeed exist, but I can't see it happening in the real world.

Fuel pressures.........
Quote:
The first thing you usually do when performing a CIS troubleshooting procedure is to determine the fuel pressures. Without knowing these pressures, you'll be relying a lot on guess work. There are two things you should concentrate on, fuel pressures and vacuum leak. Check that the fuel pressures are within spec for your initial trouble shooting. The cold control and system pressures could almost tell you if you'll have starting problem. Keep us posted, Tony |

Thanks Tony. I think you are right...I started a new post based on my checks today.
Do I have a Fuel Problem?
