GMC sierra ignition switch

Dear Barbara,

I own a 1998 GMC Sierra Pickup with a Vortec V-8 engine. The problem that I am having is that the engine is hard to start and when it does there is the smell of raw fuel, the engine is sluggish, it misses and the check engine light is on. I have had the spark plugs, wires, distributor cap, rotor, oxygen sensors, fuel pump, fuel filter, muffler and catalytic converter changed. But, the problem persists. Please help.

Dear AD,

I want you to try this method of madness:

Try to crank your vehicle for 2 seconds and let off the key then repeat this process…if your truck starts faster with this method you have a bad ignition switch. This proves you are getting power everywhere else but to the coil, meaning you have fuel but no spark. Bottom line, replace your ignition switch in order to relive your angst!

Thanks for the question.
