Starting problems

[bears4ever]

I have a 68 coupe. All new and rebuilt everything. The problem I seem to be having seems simple but yet I can't put my finger on it. I went today to start my car and no problem a couple of cranks and she fires. When I take it out and stop somewhere (ie gas) When i go to start it again you have to crank it over and over before she fires. You also have to give her gas to get it to go. Any help would be greatly appreciated.

Not sure if this helps

Hey steve,

I kind of had the same problem recently, check your fuel filter and/fuel sender and tank to see if anything get clogged up when gas is being splashed around ie when driving and it settles when stopped. I found it out when I stuck a 2 gal tank in the engine compartment and drove it that way to see if it was fuel delivery.

make sure your gas lines are staying away from heat sources, might be something there. Is the starter turning over fine? Mine used to get heat soaked and it wouldnt start for awhile until it cooled down.

Hi Guys

Thanks for the reply.
I dont believe it to be a sending unit or gas line problem. The car runs great and idles great. it only seems to happen when i have driven the car and it has warmed up. She cranks over nice. The fuel line is nowhere near any heat. I was wondering if it could be a fuel/idle mixture problem? If the car was running to rich would it put too much fuel into the carb? I'm running with a pertronix pointless system. I dont have a flame thrower coil or anything else. If i was to go out now and start the car she would start right up after a couple of cranks.

Same thought on the starter check it to see if it has any silver on the inside of the housing. If so it's heated up one too many times replace it and then get a heat shield for it had this problem with a earlier Mustang I owned although it was a 68.

We have some serious carb guys on here and I am not one of them. But....when is the last time u checked the floats?

I have the same thought about the "heat soak" issue. Mine has always done that to some extent, especially after adding the Tri-Y long tube headers. My AutoZone starters usually only last a year or two, and then they're toast. Not sure if it's the starter quality or just the heat, but when it cranks really slow when hot, I know it's time for a "lifetime warranty" new one.

Hi Guys

I haven't checked the float level. Start up when cold is good. i took the car yesterday to pick up my daughter from school(2min drive). 20min later i go to start it and it just takes too long to start. Could it be the timing? I do know i'm not using a vacum advance but the option is there. Could the timing be to far forward? Is it possible that the carb is flooding?

[rwhite65]

Too far advanced in the timing will make it start with real slow revolutions, kinda like a low battery. I am leaning towards the flooding right now.

Doubt it is the timing. If it was too far advanced the engine would hold back and not want to turn over.

Flooding sounds good. Why don't you try it at home, or where ever you work on the car. Run it like you usually do, shut it off and then wait the length of time you usually do also. Then try and start it. If it doesn't start right away. Stop trying and pull one or two center spark plugs and see if they are "wet". That will tell you if the carb is flooding.

I will try that this week and let you guys know what happens. thanks again
