1999 LS1 no spark on right side (passenger)
Hi all, my ride is a 1935 Buick Street Rod. It has a 1999 Pontiac LS1 engine and auto transmission. It was installed in the '03-04 time frame and has been running great. I purchased it in '01 and have driven it W/O any problems. Drove it the other day and parked it, running great. Tried to crank it a couple of days later and cranks over but won't start. Put a ODBII scanner on and shows no problems. Fuel pressure shows 55PSI. Checked spark on left (drivers) side OK, right side (passenger) no spark (checked 2 plugs). Where do I start to troubleshoot?

Thanks all, finally found the problem. It was a relay connected to the fuse panel. When the relay was removed the engine started, re-inserted the same relay and still started. Go-figure, at least if it happens again I know where to look.
