Starts and dies, no codes
I need some advice on this.
2006 3.5L Colorado. The Passlock had the "wire snip fix" done by the previous owner 5 or so years ago. I've had it for 1.5 years without a problem.
About a month ago, during a rainstorm the CEL came on for a day then went out. I was finally able to get a scan tool, Bluetooth model KIWI 3 OBD2 reader, and used Torque APP to check the codes. 2 historic codes came up, fuel bank and cam position sensor. Those were cleared from memory and the the truck was started but not driven a couple times. No codes came back on. It sat for about 5 hours before I tried to drive it.
It cranks and starts, idles for about 1 to 2 seconds then dies.
What I know so far.
If I listen by the fuel filler neck I can hear the fuel pump kick on the first time the key is turned but there is no noise with any subsequent key rotations. However the fuel pump relay clicks on with each key turn. After about 3 or 4 tries at starting the engine cranks but sounds like it's just moving air and will not start.
Prior to all this starting the pass lock light stayed on all the time. It still is, but now the remote no longer locks or unlocks the doors but it will arm and disarm the factory alarm. While sitting in the truck if I hit the lock/unlock on the fob I can hear a relay? under the dash click but nothing happens with the doors. Also if the door is open and I hit the lock on the door I get 7 chimes the first time and 5 chimes there after. Otherwise there has never been and door open chimes.
Any advice on this will be very helpful. If more info is needed please ask.
