I've got an 88 with TBI. The past couple of days it been starting really hard. The starter fires up no problem but the engine just doesn't seem to want to turn over. After a couple of tries and the gas pedal applied slightly it fires up , with a cloud of blueish-white smoke, which can't be good. It has a new starter, cables, and battery. Not sure what it may be, but any suggestions are welcomed. Thanks!!
