1992 Pontiac Bonneville – no spark to the plugs

Dear Doctor: My 1992 Pontiac Bonneville with a 3.8 V-6 engine has individual removable coil packs, controlling two plugs each. I have no spark to the plugs. Fuel pressure is at specification. What do I need to look for? Troy

Dear Troy: Does the car have an anti-theft light flashing or an aftermarket alarm system? If so, then these systems need to be checked first. Crankshaft position sensors are more common problem areas than the ignition module. Poor ground connections at the ignition modules are also common problems.
