Bought an 88 Subourbon tonight, 6.2, 4x, They were using ether to fire it up, and if warm it does by itself. Did a little searching here tonight, and found that is bad ****, so........ Are the Glow Plugs that Autozone lists for $10 apiece really the ticket? The light works, how do I tell that they don't, other than the not firing? Been a toyota guy for awhile, and the only GM I have ever owned were EFI types, that and a 2.8 carby or two that scared the hell outta me, reliability wise. The general consensus on the board from what I have read is that my 6.2 is an ok motor, jus under powered, but adequate. Any info will help. Thanks.
