My truck has been starting really hard, and sometimes not at all. The batteries are brand new. It seems like the grid heater is not working. is there a way to sheck it? also the other morning I had my truck pluged in and it started the sam as before without being pluged in. [undecided] ???

 

If the battery voltage is not being pulled down by the start cycles, then the grids aren't working.<br><br>Depending on the temperature, and how long you plug the block heater in for, the heater might not make much difference starting the truck if the grids aren't working.<br><br>However, you might have a timing (injection pump) or valve adjustment problem.<br><br>Excessively retarded engines are hard to start.<br><br>Good luck!

 

dodgeman01<br><br>The Haynes manual has pretty good instructions on checking the whole grid heater system. All you need is a multi-meter. I just went through mine and ended up replacing the relays under the battery. (one was bad but you gotta buy both together : )<br><br>Have you checked your fuel hoses? Maybe you're getting some air in the system. How's the shut down solenoid? Good luck with it.
