Three days ago, I started my vehicle after cranking for about 10-15 seconds it started, it usually starts right up. I just drove it to the front of my garage and parked it, after a few minutes I tried to start it but no go. There are no fault codes registered on the OBD. The engine turns over just fine. There is no power going to the fuel pump when I turn the key on, no sound of the pump running. I jumped the pump to make sure it was working, and it ran just fine. I checked the crank shaft position sensor with a multi meter, it tested good. All fuses are good, no wires loose on the PDC or fuse block. 12-volt power pin 2 and 22 to PCM checks good. Checked the grounds on PMC 31 and 32 they were about.8 ohms. I opened the wire loom to confirm both +5-volt supplies pin 17 and 31 were good with key in run position, which they were, and I was tugging pretty good on the wires. I decided to try and start the engine, no go, I left the key in the run position. As I was coming back to the front of the vehicle, I heard relays pick up, so I tried to start the engine again and it started right up. I thought maybe there was a loose connector pin or splice in the wire loom. So, I shut the engine off and checked the C1 connector all was okay there. Next, I checked S121, S134 and S130 splice connections, nothing seemed loose. I removed the battery and the temperature sensor and taped up the wire loom, checked the temperature sensor it checked out. The next day I replaced the battery and temperature sensor and tried to start the engine after two attempts of about 10 seconds and holding the throttle down it started. I let the engine run for a couple minutes and took it for a test drive, all normal, good power for about half a mile then the check engine light, 4x4 indicator came on. I pulled over and engaged the 4x4 low, high, neutral back to 2-wheel drive. Drove for another 100 yards and all gauges went off, the instrument panel lit up like the key was just turned on then a few seconds later the gauges went back to normal readings. The check engine, 4x4, and I believe the SKIS lights stayed on. I drove home parked and shut the engine off then tried to start again but no go. No fault codes on the OBD, no power to the fuel pump. Hoping you can help me out.
