348 Spider Hot start problem, help anyone?

My basically identical Mondial T had the exact same problem.

I fitted a relay near the starter as the voltage drop is to high to move the starter solenoid when the engine heats it up.
Cost: less than 10$

Or short: The wire from the driving wheel to the starter motor is to thin.

 

For the first time in 3 years, mine did the exact same thing this weekend. What'd I do? Step into a restaurant with some FCA friends, drink a few Diet Cokes, have a stomboli, and go back outside in an hour. Bingo! Car fired right up.

Ahem... Paging ferrarioldman! Paging ferrarioldman! Let's add this to the "to do" list this fall.

 

I have a 91 348TS eurospec,yes if I have driven the car for a while ,it will not start immediately.It chokes,if you feather the gas a little it will start,but the best way is to let it cool down for about 30 minutes.I have been told when the cats get hot,this may also cause the problem as well,just my 2 cents.

 

It sounds like you have a problem with the stupid bullet connectors. Run solid cables from the positive terminal on the battery to the starter, and from the negative terminal to the frame. That should get rid of the problem.

If it does it again, before you change the bullet connectors, try unplugging the connector under the air box and then reconnect it, or the one near the battery. The bullet connectors are notorious for making bad contacts.

As for the cats getting hot, unless you are getting a slow down light the ecu's shouldn't shut down the engine.

 

Don't tell me you still have the bullet connectors?????

 

Had the same thing done to mine - been fine ever since.

Evidently the hot start problem is different than mine.
You mean the starter doesn't turn right?

If it's a grounding problem can you just take a jumper cable and
connect it to the negative terminal of the battery and then to the
engine somewhere to test the theory?? A thought.

My car is cranking, just doesn't start easily when hot
which is "starting" to annoy me at present...

 

No, well.
I went through every connector in the engine bay on my 348 last night putting that stabilant stuff on them.
I think the connectors they are talking about are those big plastic looking plugs.
mine has one on the rear fender near the battery and one under the air filter box. they are pull apart and the metal contacts inside one looks like the point of a new crayon mate part looks like a hollow cone from the bottom.
by the size of it they look like pure crap and that's coming from an EE.
I'm amazed they can handle the current. I can see why heat and corrosion can change the resistance of the connection and cause all kinds of problems.

But a lot of things amaze me on this car...
anyway I think I found the hard start problem with mine, need a part to verify.

 

properly maintained these cars will start fine until something in the wiring starts to go south. Then you find it repair it and you are fine. Barring that here is the bandaid:

1-no start no crank put a $10 ford lincoln mark 3 1980's vintage solinoid in a remote location. This will work until the wires really go south.

2- no start but cranks check flywheel for grease

additional diagnosis to prove 1 or 2 use a remote starter with key in on position and trigger starter from starter solinoid with remote starter. Starts = bad wiring. Cranking only = bad flywheel grease pack

FWIW when I had my 348 as a streetcar I always traveled with a remote starter. This will get you going when you do not have the time for a beer and you need to get going now!
