"They" don't know what they are talking about. First, the word is intermittent. Second, people who know NOTHING about electronics describe all electrical problems as "a short". Third, I don't see how a "load tester" would show you there is a short - a short is found by measuring current, not putting a load tester on the battery.



An engine that cranks but won't start is often suffering from one of the following:

1) Bad Crankshaft position sensor (does not always light the check engine light; always buy a BOSCH part)
2) Bad solder connections on the Relay Control Module (pull the module and have someone resolder any cracked connection, better yet, resolder ALL connections on the board)
3) Bad Battery (yes, a battery that cranks the engine may not start the engine...)

A less likely problem would be a bad CAMshaft Position Sensor, problems with the security system, bad fuel pump/filter, bad MAF sensor or other sensor...
