| What might be the problem? Won\'t start when hot!
Hi All
I have done a search, but can't find what I need.
Why won't my GTD40 start when hot?
I have had this problem ever since I bought the car and it is a tad inconvenient to say the least. Basically the chain of events are as follows.....
The car starts fine when cold, but when hot the starter motor didn't turn over properly - it sounded like a flat battery - whrrrrr........whrrrrr.................whrrr. If that makes sense!
So far I have done the following....
Upgraded all the earth leads on the car and made sure there are good earth points on the chassis.
Upgraded the starter motor to a high torque unit from Mark at MDA. It turns over now like a jet engine - much better! When hot it is a bit slower, but turns the engine over fine.
The engine bay gets really hot, but I have upgraded the water pump to an EWP electric pump and this works very well.
Car still won't start!
What should I look at now?
As I have said before, I am not a mechanic - I just about have "blonde" knowledge of how an engine works, however, I can follow instructions very well!
I have a standard GTD double fuel pump set-up and elderbrock performer head etc. Mallory electronic ignition. Carter carb.
I think it must be a fuel problem - is the heat soak of the engine evaporating the fuel before it gets to the carter carb? The engine turns over, but never sounds like it will fire.
If I wrapped the exhaust - would this help? Should I sheild the starter motor? Any other suggestions...HELP!
Thank you for any ideas you might have.
