Dam 914 still doesn’t start regularly Options

[Kevan]

My 914 still doesn’t start regularly. I turn the key and every time I heir the buzz my guess is the D-Jet fuel pumping and then it might start or nothing happens. Once it starts cranking it will start just fine. Here is a list of what I’ve done. What am I missing??? What could be wrong?

New battery
Clean the connections on the battery
New ends on the positive wires to the battery
New ignition switch
Clean and replaced connections on the starter solenoid
Cleaned ground strap connections from tranny to trunk

Newbie here, What about after driving for a while,turn car off,finish errands,hop into car and she doesn't start? I've grown to hear it's a "Heat" issue.
Thus a relay is the answer.Had mind for over 20 years,no problems.Before relay,GRRRRRrrrr!No starting!

What I think you are describing is the problem of a vapor lock heat soak condition. (where it will crank but not start) This is usually solved by relocating the fuel pump up front under the fuel tank where it won't suck air bubbles.

In my experience (30+years with these cars) when the car won't crank only when very hot, it is a starter issue. (That's why if you whack the starter, it will sometimes start cranking) If it is a sluggish cranking, you need to check the grounds and the battery condition. On rare occasion, I have seen positive battery cables that were very hard/brittle with high resistance and needed replacement (I think that was caused by a charging related problem).
