Intermittent Starting Problem

[Boatnut]

Checking, cleaning and replacing connectors, especially crimp on connectors as suggested several times will most likely solve your problem. Take note that when one of these connections fail, you can be pretty sure others will soon follow. Being that the solenoid activates your problem is most likely one of the large wires or connectors causing the problem.

The problem is called a high resisance connection, it will often lead one astray in the troubleshooting process because it will show voltage is good with no load on the circuit, when the load is applied the voltage will drop due to the high resistance connection. Have someone try starting the engine while you are reading the voltage, start at the starter and work back toward the source. Don't overlook the possibility that the start solenoid is bad. The starter is easily checked by shorting the heavy contacts together, this will make the started energize, if you don't know how to do this get someone who does to help you. Good luck
