1994 Buick LeSabre Q&A
1994 Buick LeSabre Question: i changed plugs & wires then eng would turn but not start.
Check fuel pressure before start up, maybe plugs are coincidental. - ProfessorG
After getting more info than was first posted, which always helps, hold gas pedal to the floor while cranking next time to see if it helps.. Can pull the wires off one of the coils to check for ignition fire between coil towers while helper cranks engine. Dont cross wires when putting them back on, easy to do!! Post the results. Were the 'other' spark plug tips wet when you pulled them out after cranking on the engine? BTW, This can be tested with a scanner for possible TPS or CTS issue which can also cause yout trouble. - pushrod
