Damn it, starting problems when hot

Stang_1973 · Jan 12, 2006

Well, recently I have just been taking the stang up and down the street since i dont have registration, or inspection tags yet but I dont want the engine and the car to just sit around.

Any way i drove it for about 10 minutes and parked her back in the drive way. My dad asked me to move the car about 30 seconds later cause he was leaving and i was blocking him in. So i go to turn on the car and its like.

CRR----CRRR--- CRRVrooom.... and then she idles normal. However, what is the deal with the hard start. It has done the same thing a few times again. It has no problem starting when cold, only once you have driven it around for a while. Could it be just a bad starter? hot selenoid?

Sounds like your timing is set too high.

krash kendall · Jan 12, 2006

Yes, or poor ground or bad wire.

yeah I notice the same thing with my car once in a while. What do u mean by bad ground or bad wire? I replaced my battery cabels last year, they dont have acid build up because I clean them. And by wire, which wire are u talking about, cause there are like 5 million of em lol. I just replaced my ignition coil so it cant be that wire.

I have heard of this....

If the timing is set tooo high, will that make the engine sound accelerated?

If your headers are close to your starter, it may be heating it up reducing it's cranking efficiency. Maybe a heat shield will help.

usually the most common ground wire that's missing is the strap from the engine to the firewall. that could cause trouble, but then again so would improper timing, a bad starter, solenoid or even a bad battery. i would check the timing before you do much else.

if your timing is ok,and grounds are good,have somebody hold the cable that goes to the starter as you crank it to see if gets hot.I used to have hot start problems from heat soaking the starter,bought me a cheap-e starter from Chiefs(Autozone) and it never did it again.

Does the cars engine knock a bit when you turn it off after its warmed up?

Did you find the problem???, I have a 66 with a 5.0 from a 1989 Mustang, doing the same thing..let me know please... I did notice that I'm missing the ground cable to the engine. thanks for your time

If any electrical cable feels hot to the touch during and after use, there isn't enough capacity to carry the load going through it. Yes, it could be the starter not taking the load, or the cable going bad from the inside out, where you can't see it from the outside. Good luck.

honestly I have been too busy get anything done with my Baby, the '73. Work and school are pretty much owning me as well as a project I have going at my dad's. I have been buliding him a custom gate for his new entry way to his driveway. As soon as i find anything, i let you know.

BTW: 4muscle machines: I dont think heard any knocking, Will look for next time though. What could the knocking after turning off suggest?

Yah I have the same problem, but I do have a fuel supply issue I need to address that could be the problem.

MitchGT · Jan 17, 2006

buy a heat shield ( a reflective blanket held on by metal straps). they're fairly cheap and it will solve that problem. I have long tube headers that get too close to my starter, and I had that same problem. I put on the shield and it stopped.

good ideas already posted.
I had an issue with hot starts on my 65.
Turned out to be a worn bushing on the bendix gear, causing it to bind when the engine and thus the starter was at operating temp.
Fixed it for less than a big mac.

This is common for poor hot-starts. Worth checking!

Damn it, starting problems when hot
