hot engine vs starter

[LanceJones]

Anyone has this problem? When my engine is cold and I start it, it fires right up. But when I start it when I 've driven, or let's just say when the engine is hot, it seems like the starter (or solenoid?) doesn't want to anymore...?

It sounds to me like you might have a resistance problem. As heat increases so does resistance. I would check my battery cables, paying special attention to the negative cable. You don't wanna just check resistance. It's better to do a voltage drop test with a voltmeter. Good luck!

I had the same problem on a slightly modified engine. I bought a high torque starter and all problems went away.

you might just have the timing too far advanced,seen it happen before,when it's hot it can affect starting,check that other stuff too

Hi,

I did not catch your problem... is it cranking?

If so... check your coil. (Had a Ford that did not start when cranked after engine was hot from running).

If not... check the wiring at the solnoid, any loose or corroded wires will keep inition and starting from happening... even if engine is hot or warm after use.

Excesive oil leakage at the oil pump... check with a shop rag and wipe the starter for oil. If there is a lot of it (usually very grimey) the starter is burning up the stator and brushes by oil collection from oil blow by.

Those are the most overlooked area's for starting issues.

Put in a new cable from the solenoid to starter, same problem
Also cleaned the bolts on the starter today, I read somewhere that if they get dirty or greasy from oil they might not give a good ground.. and these bolts were indeed verrry greasy (but still not convinced)

Really bummed out cause yesterday I drove it for testing, started again and starter going round very slow... and you just know that's when people are lookin'

On another note, could it be the coil for real and if so, can I put in an MSD blaster coil (pn 8223) with a conventional distributor?

i went to buy a new coil for my 68 amx 390 automatic and when they brought it out , on the side of the coil it said to use with an external resistor ?? i have never seen a resistor on this car does it have one ?? i traced the wire from the coil and it goes into the firewall and no resistor in site ?? is it under the dash ?? i thought it took just a plain 12volt coil .. i didn`t want to buy the wrong item so i`m double checking .. can someone clear this up thanx ..
