Hot Start?, Ticked off owner! Options

[Razorbobsr]

Getting my car back from Porsche guy, drove 70 miles to home just fine. Get off interstate and engine stalls, hit key and nothing!!! Tach pegs at 7000 but no starter engagement, do have hot start kit. Car ran GREAT all the way home. Ideas? Help needed!! Thanks Bob

An easy way to cut the problem in half is:
Remove the large yellow wire from the starter solenoid and check for 12 volts between that wire and ground when trying to start. If you have 12 volts, then there is probably a starter solenoid problem. Gently tap the solenoid, hook up the yellow wire, and try again, sometimes the heat causes the solenoid to bind and not connect the batt to starter contacts. If greatly less than 12 volts, (Less than 9 volts), you have a connection problem between the key switch and the starter solenoid yellow wire. Possible ground problem also, check negative batt terminal and large ground strap at transmission.
In case you are not aware, the solenoid does two things; moves the starter motor gear out to connect with the flywheel, and makes two electrical connnection with two large contacts to give the starter motor the voltage and current to turn the starter motor.

Had the car flat bedded home, tried to start, same same. 12 V directly from battery to starter/ starter spins strongly/ ever so slightly moved solenoid wires/ car started!!!!!!!!!!!! Car has mostly sat last 2 yrs due to impending death in the family, but has been started fairly often and always started, had this same prob when driving car back from FL at gas a motel stops. What I dont understand is the fact that even after a long run, and a no re-start, cooling period, still no start! I am going to remove starter wires one at a time today, clean/wire brush each of them, and apply die-elect grease. I am thinking strongly about one of those HI-Touque starters????? I have them on 2 other Hi-po british cars and they work well with heat. Bob
