I'm a first time poster here but I've used the site many times to fix problems.

My car just decided not to start this afternoon. It was running fine when I went to the store.I came out of the store and it cranks over fine but won't start. I checked with a timing light and I'm getting spark at the plugs. I located the OVP relay and checked the fuse and it was fine.
Should I replace the relay anyhow ?
I'm at a loss on what to do now .

Thanks in advance .
