2004 honda accord 3.0 ex crank but no start
I have a 2004 honda accord 3.0 ex. Automatic transmission
Got it from my neighbor a few weeks ago. When I got it, it ran fine, little slip in the transmission, but not the problem I'm concerned about.
The check engine light was on so I checked the code and found it to be regarding my knock sensor. Got a new knock sensor and new wiring for it (old wiring was chewed all the way through. To replace the knock sensor I removed the power steering pump & pulley to access the knock sensor. The car sat for a few days before I put the power steering back and put a new serpentine belt on.
I went to start the car. It cranked but did not start. First I checked for fuel by disconnecting a quick connect fitting in the engine bay. Fuel pump primed like normal. (don't know my fuel pressure, I just know I have fuel). Check for spark at plug, nothing. Checked for spark at coil pack, nothing. Check voltage at 3 pin wiring harness, 1 pin had constant 12vdc. Other two pins have nothing with key in any position including while engine cranks. I checked my ohms from pin to pin. Everything seemed to be right in line with everything I read online. Checked my fuses and relays and verified that I do have power at my fuse and through my relays. I also checked my battery with a test to verify it is still good.
I have tried to be thorough and trace my voltage down the line to find the culprit, but to no avail. Any advice would be much appreciated.
