Hello Forum - I am new to the forum and have run into a recent problem with my 03 chevy tahoe Z71. I recently replaced the power steering pump and water pump at the same time. Typical job nothing out of the ordinary. Upon completion the truck would not start. I did not bother anything that would affect ignition at all. I checekd all of the fuses and relays and they were all good, but I can't get a spark from my plugs. The only thing I can think is that when I was doing the work on the truck, I had it pulled 1/4 of the way into the garage with hood up, and it was raining. Rain could have possibly run down into the firewall. Anyone have any inklings on a direction I could go in order to try and fix this issue. Thanks!
