Question about 1993 GMC Sierra K1500
Two things kill engines faster than anything 1) fuel 2 ) ignition So 1) Fuel coming through line at good volumes and pressure? fuel pump and its electrical supply in good shape? In-line fuel filter not clogged? Does she fire if you squirt Easy Start (raw alcohol) in the throttle throat? Is the fuel fresh and not rancid stuff that has been sitting in a can for years? No disconnected hoses (crank case breather/relief pipe) to the inlet manifold to cause loss of vacuum? and 2) Timing? leads in right order from dist cap? fuses all OK? can you see spark jumping from top of coil to HT lead when disconnected but brought up close? check that low tension wires are on the correct terminals.
