2002 Oldsmobile Silhouette not starting
My sons was driving the van and it stalled. When he started it again, it cranked over but would not stay running. towed it home. Changed out the crank sensor, spark plugs, and coil pack. We have pressure at the fuel pump (50). Not getting a spark to get the engine. Battery is good. Cables are good. Starter is good. Alternator is good. Not sure why we are not getting spark. Any ideas on how to proceed at this point?
