2000 gmc jimmy issue starting
V6 vortex 4x4
Has major problems starting after it sits overnight , if your lucky and you get it running it will restart perfect....it's kicking me around.NO CODES
I've replaced cam and cranksensor ,tps,fuel pump,ignition module , new distributor,fuel pressure is good , I originally thought the passlock system was the problem but it does same thing with no flashing security, usually if you disconnect the battery, wait a few, reconnect it starts ( no every time ) I can jump the fuel relay force run and it still won't start, exactly what happen is turn key to start engine starts for 2 seconds and stops ,try again does same thing , if your lucky and it starts with no cut off it runs just fine, and will restart fine but let it sit several hours and same issue over and over and Im stumped, please help
when it did start it throwed me a code P1351
Probe the ignition control module harness connector terminal B with a DMM connected to a ground.
With the DMM set to the AC scale, crank the engine.
Monitor the voltage reading. It should be between 1-4V
Where are you? Reset the computer by disconnecting the battery so I'm assuming you have a main computer failure or wiring to the main computer that's failing
