Consider the starting system here
Replying to Joel Damir’s problem (August Mechanic On Duty), it looks like the troubleshooting advice omitted several items in the start system. (His truck won’t start after a short drive.)
I always take a look at what starts the car. It is quite clear that the relays were looked at but while we were checking the relays the starter was cooling down. There was no mention of starter checks.
The neutral start safety switch also could have corrosion on it that prevents it from making a complete connection. After the initial start, resistance may be inhibiting the connection until after several attempts are made.
Still another area that has caused me great concern in some of my vehicles was the relay connections. Underneath the relay box the battery has corroded the connections. A few more checks could resolve this problem.
