i would check the battery and load test it to see if its ok,then check the starter,sounds like it is dragging or needs rebuilt/replaced. Do a voltage drop test from the battery to the solenoid and a drop test on the negative cables,check for good ground connection on negative cable from battery.
Yes it cranks and trys to turn over. If I hold down the gas pedal it almost makes it.
"it will crank but not turn over"?? Does it just make a click or does the starter turn the flywheel and just wont fire?
