68 Camaro wont start

We have a 68 camaro with a 327 with a four barrel in it. It was running really good. Then we were driving and it just killed. It started up after a few minutes. Drove it a while more and it killed again. Started again but took awhile. Next day it ran fine, no problems at all. Third day we took it out, running great then just quit. We could not get it started again. It just cranks over but does not start. Can see gas going into the carb. Im young and just getting into cars so I do not have alot of mechanical knowledge. Any ideas would be appreciated. Thanks

Re: 68 camaro wont start

The good news is these cars are pretty simple, no computers to muck with just need spark and fuel. Almost sounds like a fuel delivery problem but you said you have fuel in the carb so I would start by checking for spark. It could be several things including a bad coil wire or coil, weak battery, bad grounds, bad starter.... etc. Start with the simple stuff. Take a volt meter to your battery, is it at least 11.5 volts ? Check the ground cables and straps - battery to engine, engine to chassis. Are they tight and do they look good ? Replace them if at all questionable. These cars require solid grounds to start. Check the battery cable and ignition lead on the starter - are they tight and in good shape ? If these check out then pull the coil lead to the distributor and see if you get spark. If you don't have spark then its wire or coil. If you do have spark then check at the spark plug end. If you have spark to the plugs then it has to be fuel delivery. ie: bad gas, clogged fuel filter, crap in the carb.

Re: 68 camaro wont start

I agree....sounds like a bad coil.
Goes bad after it heats up then works again after it cools down.

Good luck

Re: 68 camaro wont start

Could also be something stupid like what happened to me....distributor hold down came lose...then it rotated and the timing was all out of whack. Sometimes it would start if it would rotate in just the right direction...tightened it down and re-timed it and it now starts right up.

Re: 68 camaro wont start

This car uses a point style distributor and the points just may have closed up from wear and need replacing. A common problem on these old cars.

Re: 68 camaro wont start

sound like point gap closing up and caused resister next to points to fry-replace points and resister -gap points at .019 to get it started or see if it starts

Re: 68 camaro wont start

o and one other thing if you didnt know--if leave your key in on position to do testing or radio ect. without it running can cause hot spots on points and burn them out

Re: 68 Camaro wont start

If you have tried everything these guys are telling you and nothing works, (and you don't have any spark) it's prolly the magnetic pickup in the distributor. They wear out like anything else over time and can be a pain to diagnose. But I have had them do exactly what you are describing.

Re: 68 Camaro wont start

a long shot, after all the above, if you are sure it has gas when it does not start forget what im going to say
if not, make sure gas tank is painted silver and not black. might be old time vapor lock if the car is pure stock and orginal. like i said, long shot
