My check engine light came on while driving home from a friends place the other day. At the same time my battery gauge dropped off like it stopped working. While I was stopped at a stop light the truck took a second to get going, pedal response for gas didnt respond right away. When I got home I shutoff the truck and tried to restart the truck but it wouldnt start. Just keeps turning over. Ive replaced the battery, but Im at a loss for anything else. I did get an error code of P1389 on my reader when I hooked that up. ANy help would be appreciated. THanks!

I have checked it. At least I think I have. I switched out the ASD relay fuse with with wiper fuse. Same fuse. Still same thing. If thats not the ASD relay, where is it.

Load test alternator if okay recheck the ASD relay in the power distribution center-dunno the exact location. This relay plays a major role in the fuel/ignition system it powers the coil/fuel pump/injectors

I haven't load tested the alternator yet because I dont have the equipment to do that. Ive replaced the battery, since its about 4 yrs old. Shouldn't a brand new battery have enough juice to start the truck? I've also checked the fuel pump, that works. I've taken a closer look at my Code reader (Cheap one) and I saw 3 lights that were flashing that came up, I read one of the lights was the O2 sensor. Could the O2 sensor cause it to not start?

The oxygen sensor will not prevent the engine from starting, something else is causing it. Fuel pump might be coming On but is it producing the correct fuel pressure and aslo are the injectors pusling

I checked at the fuel port valve on the side of teh engine to see if I was getting pressure. When I pushed the button, I had fuel come out. Then after I kept it open to make sure nothing else was coming out I let it go, then tried to start the truck again. I pushed the button again and had fuel almsot spray me in the face. Lol. How can I check to see if its the correct pressure.
