she won't turn over....
Gents,
Recently replaced the alternator, plugs, wires, distributor cap, coil on my 67.... went to go crank her up. she cranks but won't turn over. the one time she did turn over she was shaking side to side real bad... Now, I made sure that I labeled the wires properly before putting new ones on.... I also know that there are a lot of variables but wasn't sure if someone could pinpoint what it was. I'm using platinum plugs where as before they were stock. a new msd coil and new distributor cap as well. the alternator, cranks when I turn the key but i'm assuming it's not starting because of lack of spark. Thanks, Chris |

Re: she won't turn over....
Let me get you straight,for starters.Turn over and crank are the same thing.I think you mean it won`t fire.The starter,alternater,and battery are suspect when won`t crank and won`t fire is either fuel or ignition.
You need to check fuel delivery and spark/timing.See if fuel is gusg=hing from the fuel pump.Is it a Q-jet carb?Remove the line at the carb and check the filter.Work the throttle and see if it`s squirting.You can hear and see it looking into the carb.If no squirt the accelerator pump in the carb is week.How old is the fuel?See if it will run with a little gas poured in the carb to eliminate the fuel problem. Check spark by seeing what color it is holding a plug wire close to the motor to cause an arc.Check the coil wire the same.Is it HEI or points?You didn`t mention points. The only other thing would be timing.Is the distributor real tight?

Re: she won't turn over....
Yup, she won't fire.... she cranks, the alternator/belt move. The carb is a new edelbrock 1406. She worked before putting on all the new stuff. I can smell fuel after cranking for a bait coming from the carb. The filter is as new as the carb. about a month. Forgive my ignorance but i'm not sure if it's hei or points. How can I tell? The distributor is tight. I also put the new msd coil on.

Re: she won't turn over....
When you removed the cap, did you mark on the firewall which way the rotor was facing?
Did you remove the distributor at all? If your getting fuel, then check spark. Good Luck and you will get thru it.

Re: she won't turn over....
gotcha... here is what she looked like before. I'm fairly certain, by your descriptions that i'm running points. Going to start with wires/plugs and go from there. thanks guys

Re: she won't turn over....
This is when an extra set of hands come in handy... I usually have someone crank the engine while I remove a sparkplug wire and check to see if there's a spark to the plug.
If there's not, I remove the coil wire from the distributor and again have someone crank the engine while I place the wire close to the center post to see if I get spark. If there's spark there, then I know it something inside the distributor like point gap, condener, short or loose wire in the points. That is, if the timing has not been changed. In my case (68 GMC) I had the wire come off the points... I don't like those cheap press on, friction contact types. If you have that kind check with NAPA. |

Re: she won't turn over....
You probably need new points to really tune it up.Maybe you cqan get someone more familiar with them to show you how to do it.It's not really a hard procedure but it requires some care(you don't want to drop any little screws).Some special tools are handy also.

Re: she won't turn over....
one other thing, I didn't change the rotor... only the distributor cap..

Re: she won't turn over....
You likely hooked up the coil wires wrong or plug wires are wrong. Start with the simplest stuff first. No offense, but something you did is likely not correct. Happens to all of us. Go back and re-check everything you did and make sure all is 100% correct. Plug wires, coil wires, etc. Also make sure the wires going to coil are not broken. They look pretty bad and may have broken during removal/installation. Find the firing order and make sure each plug wire is correct. Make sure they are on the cap correctly. Don't move on to anything else until you recheck all you did and confirm it is correct. Good luck.

Re: she won't turn over....
Cool. I'll go over it again. No offense taken. It's likely that I messed up the order... I hope it's that simple anyway

Re: she won't turn over....
I'm not seeing a ballast resistor in the picture (white porcelain block with two terminals on it). Did you remove it when you did the other work, or is it just out of frame? Its been a while since I've run points, but I do know that you must have a ballast resistor in line before the coil for the system to operate properly.
Also make sure you got a coil that was made for points ignition and not an electronic ignition. Craig Last edited by cleszkie; 06-16-2009 at 06:11 PM. Reason: Needed to add more info. |

Re: she won't turn over....
Do you have an after pic showing where the wires to the + and - sides of the coil go? Something doesn't look right. 12V should go to pos. neg. side to distributor.

Re: she won't turn over....
Aside from everything,you should replace the rotor and points.You`re smelling fuel because you`re getting the gas and it`s not being burnt.Definately ignition.Give a "now" picture like John suggested.We may see a problem.

Re: she won't turn over....
I agree with Special-K in that you should replace the rotor and probably the points and condenser.
But first you need to figure out what you did that is causing it to not start. One= The alternator has no bearing on if the truck starts or runs as long as it has kept the battery charged. That is all it is there for, to charge the battery and provide electrical current to the truck. If you have a fully charged battery you don't need the alternator operating or even on the engine for the engine to start. I am like several others in that you have probably crossed two or more wires. If the wires aren't crossed you may have started with number one wire in the wrong hole and are one plug off with each wire. From looking at the wires on your old cap #1 was at the position just clockwise from but next to the window tha use to adjust the points. With #1 wire there you wire the plugs *clockwise* 1-8-4-3-6-5-7-2. 1-3-5-7 being on the driver's side of the engine (US drivers side) and 2-4-6-8 being on the passenger side numbered front to back. I've seen Ford guys try to use a Ford firing order and have seen (myself included) Oldsmobile guys wire the engine for an Olds V8. I woke up in the middle of the night after figuring that one out after fighting with the 283 in my T bucket for two days in 1973. If the wires are in the correct places and order check the rotor to make sure you didn't break it when you had the cap off or get the cap off center and have the rotor hit the inside of the cap when you first tried to crank it. |

Re: she won't turn over....
When I changed my points distributor to hei, I had the right firing order, but installed them counter clockwise instead of clockwise. It fired really rough and wouldn't stay running like you described when you did get it to fire. Drove me nuts trying to figure that one out.
Once I had a problem starting a points ignition engine and it turned out to be a hairline crack on the rotor that the spark would trace directly to ground inside the distributor, bypassing the nodes in the cap. Replaced the rotor and she fired right up. It'll do the same thing if you have moisture inside the cap. Some caps have a spring loaded carbon node at the center point of the distributor cap where the coil wire hooks up that will fall out and provide no spark for the rotor. That's all I got! ![]() Dan
