My 1979 chevy pickup will not start I have replaced the starter the flywheel and have put in a new battery and still nothing. Everything shows it has power but I turn the ignition and it acts like the battery is dead and sometimes it has no fire at all I don't know what could be the problem please help

Thanks

Does the starter motor crank the engine properly? In other words, do you have a "crank but won't start situation?"

. Test all under-dash and under-hood fuses with a test light or multimeter:

. Test for spark. If there's no spark, check the Ignition Control Module, which AutoZone will do for free:

While we find your parts, please enter your ZIP Code at PartsAmerica.com (http://www.partsamerica.com/ProductList.aspx?PartType=194&PTSet=A)

Next, check the coil, which AutoZone will also do for free.

. Test for fuel.

Slow cranking is caused by excessive resistance in the starting circuit.
Make certain that both ends of both battery cables are clean and tight.
There may actually be corrosion inside the battery cables. Try running your hand along the entire length of the cables, particularly the Positive, feeling for any abnormal bulges that would indicate corrosion.
