Ok guys, I was hoping I wouldn't have to tell you this, but you are dealing with a 50 year old woman here. I am the middleman writing to you and then I relay your answers to my husband who tries to figure out you have said.
This is our very first classic. My husband had a 1970 Chevelle when we met and when we saw this one we fell in love all over again.
Here is the whole story...
I have a 1970 Chevelle SS that is driving me crazy! I've taken it to 2 different mechanics and $800.00 later I'm still having the same problem..one day the car starts up and runs fine, a week later the car either starts up hard or doesn't start at all. If it does start and I let it run awhile when I put it in gear it stalls immediately. Then it starts right up..put in gear...stalls. I drove it all around one day and stopped in a dairy queen for an icecream and it would'nt start up again. The engine turns over but won't catch. Had to have it towed in..they replaced the ignition coil, control module, distributor cap, distrib rotor, o-ring, and fuel hose.
We saw some bad wires spliced together like I mentioned above. You would think that the 2 mechanics would have seen these right off since one of the wires was the pink one connected to the distributor.
My husband is not mechanically inclined when it comes to wiring. He recently replaced the fuel pump and fuel filter as was suggested by your answers.
So this is what we have done according to your reply. We disconnected the three wires that were spliced together-the yellow-the pink-the white cloth covered one. We taped up the yellow bypass wire. Then we connected the pink wire from the distributor with the white cloth covered resitive wire and started up the car. Is this OK or will it cause a problem???? It runs rough and takes a while to warm up to the proper RPM.
Dean you said to:I would start by making sure I had a good wire source from the fuse panel that is hot when the ignition switch is in both the "ON" and the "START" positions but not hot when in the "ACC" position and tape off the white cloth covered wire and the yellow bypass wire then make sure all splices are good.
We don't quite grasp what you mean here. What do you mean by having a good wire source from the fuse panel that is hot. How do we know if it is hot? What do we need to test it?
Dean you suggested we do this:What I did was:
I replaced the resistive cloth covered wire down to the bulk head connector with a 14 gauge stranded wire and rewraped the harness
What and where is a bulk head connector?
You can use any source that is not hot when the ignition is in the "OFF" or "ACCY" positions.
How do we test to see what is hot?
You wanted to know where the coiled up brown wire went..originally I said it went to the fuse box, but after looking closer I see that it is spliced to the black wire coming from the brown plug on the distributor and it goes into the firewall panel...could be the tach?
Dean you said:For the HEI you just need a 12 volt power source to the "BAT" terminal on the cap that is hot when the ignition switch is in the "ON" and "START" positions. What or where is the "BAT" terminal? How do I test it to see if it is hot. Shouldn't this have been wired properly by the mechanics when they replaced the distributor?
John, you said:I only questioned the blackish wire because it looks like it goes to the HEI B+ input connector. Also looks like a pink wire goes into that connector. If I understand things correctly, you are having problems in this area. Like Dean says, there should only be one wire in this connector from a switched source.
Both the black wire and the pink wire go into the brown plug you see in the picture. Could the black wire which is spliced with the brown coiled up wire be for the tach? If so, would it also be connected with the pink wire?
Toml you wrote: HEI distributors are real current suckers, according to info I have. I find it's best to run a #10 wire to a relay and then to the HEI and then use the original distributor wire (resistive or not, doesn't matter) to turn the relay on. As someone else said, there's no need for the starter "r" terminal to distributor wire any more.
What and where is a relay?
Does anybody have a picture to explain any of the above suggestions? Can anybody take digital pictures of their engine showing the wiring like I did? Or does anybody have a 1970 wiring diagram they can e-mail me at
[email protected]?
We appreciate all your help, but if you can explain things in layman terms it would really help us...Thanks...Dangee
