Hi all

I hate this when it happens!

I replaced the alternator and the air pump with new units. Before I reinstalled the new ones, I degreased that side of the engine and hosed it down sparingly. I did not do the intake side at all.

I also pulled the valve cover off to check things out. No problems, chain fine.

Reasembled everything.

The car ran fine before I did my planned maintenance. Now the engine cranks fine, but no start.

I double checked the plug wires - all correctky installed. I find no wires disconnected anywhere. I do not see anything on the exhausr side of the engine that seems electronic in nature that I could have ruined or got wet when I cleaned that side of the engine.

I see a crank trigger - maybe I got it wet, but I suspect it gets wet anyway when driving in the rain.

What do y'all think I should check?

Thanks.
