No Dice....I spoke too soon!!! The Mav petered out on my son when he was on his way home this evening. It would restart then die when he'd try to give it gas. After several attempts is returned to normal and drove fine the rest of the way home. This is very frustrating. I may swap a new coil on tomorrow and pull the tank this weekend and clean it out. Brad
i would be willing to bet the coil.... try it before you do the tank....its less work... i hope you figure it out though....maybe ask a friend to try and troubleshoot it with ya
back to the drawing board! So far i have removed the gas tank, it was VERY clean, blew out the fuel and vent lines, replaced the rubber lines, replaced the ignition module, coil and solenoid. The car is still intermittently stalling, only to start back up immediately then stall again and again, etc., until..bam!..its back to buisness as usual and runs fine until the next time. Does it hot or cold in any weather. Any ideas? Brad
Have you checked if you are getting spark and everything when it stalls? What about the pickup in the distributor?
Pretty sure he said he replaced the coil along with the ignition box and solonoid. I still say you need to figure out which system is not working. Next time it quits see if you have fire to the plugs. If not then I would check the module in the dist. they are bad to go out but at least don't cost much. I have seen the wires get worn and break from the vacuum advance moving the plate. Pull the cap and check the wires for breaks or worn insulation The module went out on my F100 (pre MSD) days. It was real hard to start once, got it running and drove it to store. Came out and it was dead, would'nt fire at all, Clint
The problem with checking for spark when it quits is that it will fire right back up, first attempt, every time. If it would just quit for good I could fix it! That's the frustrating part of it, it runs so good when it's running, which is most of the time. It has gone as long as 5 days without quitting. So the magnetic p/u in the distributer is replaceable or just the whole distributer? So far I have a new carburetor, fuel pump, fuel filter, fuel lines, coil, ignition module, solenoid and a clean gas tank. Thanks for all the help guys. Sooner or later! Brad
Brad; check in the distributer for a frayed wire or loose connection. Look under the advance plate, and see if there is anything amiss under there. This sounds like a spark problem, and since the coil and module are replaced, I would look to the distributer.
I see your point, can't ride under the hood ready to check it I don't reckon. lol I can't remember exackly but it's not hard to change. I think the reluctor wheel, with all the slots on it, has to come off. It is held on with a verticle roll pim and a tapered shaft fit. Take two large flat screw dirvers and start working it up. It will come off. Then You can either buy it with the vacuum advance plate already attached or just the module by it-self. It depends on which way you buy it that tells you what to remove It's all pretty self-explanatory. Ask us if you need some help clint
New Distributer, same deal! I'm back to thinking now that maybe it's fuel related. I just don't see how. I have a clear fuel filter between the fuel pump and carb. It rarely, if ever completely fills. Is this normal? I've cleaned the tank. Blown out the fuel and vent lines, Replaced all the rubber lines and even ran it without the gas cap. Replaced the fuel pump. Nothing helps. All the electrical components are new except the voltage regulator. It will run fine UNTIL it dies. Then it will eventually restart and run fine again. This is unbelievably frustrating. I used to dirt track, built my own cars, chassis, motor, everything, they all ran! Some of 'em pretty fast! This one's possesed! Brad
is your choke closing on you? if its a manual choke, it could be flapping and closing off the air flow... check the choke... ignition switch.... voltage regulator.... does it have a resistor that someone could have installed? just throwing out ideas... hope they give you some other areas to look at
Ok now,I take it that you checked the vacuum advance capsule on the distributor, and that it's working OK,and that you also checked the carburetor accelerator pump and it too is doing it's job. If so ,then to me it sounds like a intermittent short that's killing power to the engine , I'd look at the ignition switch (jiggle it a bit with the engine running, see if it dies out,or tries to die) then fuse box, wires etc. If You want to try something for a week or so ,you could jumper from the + side of the battery to the + side of the coil after you start the engine each time, this would insure that you have power to the coil (even if the key switch was turned off) If it runs like this without stalling then you know for sure it's somewhere in the wiring. Good Luck!
