Try not taking the bed off, just loosening it and lifting it enough up front to get your hands and tools in there.
Never would know it from behind this computer screen. Welcome.Thanks for the info!! Had the CEL for a year, then it was time to have a smog check. Trouble shot for 15 minutes (found an 'open' when measuring the resistance of old valve, supposed to get 21ohms) ordered the part on Amizon and the fix took 15 minutes, start to finish. Passed smog today and I'm on my way!!
Thanks again for the tech tips!
