Please help

Last week I was driving my truck and it just shut off like it lost all power to the PCM, the WTS light flashed and the truck died. I got it home and a couple days later I finally had a chance to mess with it. My negative battery cables were loose so I tightened them and the truck started right...

95 PSD problems

I still haven't figured out what's going on with my truck. It's going to the shop this week. I pulled off the drivers side valve cover today and the number one injector wasn't spitting oil and nothing changed when I unplugged it so I pulled off the solenoid and found a loose armature screw. I...

Ok so I pulled off the valve cover to test the injector that was reading a low number and it was working. I started it up and let it run for a few minutes and all the temps were very close. I dont know why it showed lower before. I've checked it almost everytime I run it since it started acting...

Also, I put a new icp sensor in it and nothing changed with it plugged in or not. Well today with it plugged in, the CEL finally turned off and the motor was revving up and down by itself and the gas pedal wouldnt respond. It did this with my old icp also so I assumed it was bad. Why does it do...

I started up the truck earlier and let it idle for a while. It was blowing a little white smoke, but it's been doing that since the problems started but it clears up after I start driving. After a couple minutes the throttle pedal wouldn't work and was blowing even more white smoke. After about...

That's what I was thinking since it does it in higher rpms and the fuel pressure is good. I hope it's not the problem tho.

Running, the voltage is 13.5 to just under 14. Not running its a little over 12. Ive heard that if the map sensor is unplugged and it runs better, it's bad. It runs the same unplugged as plugged in.

Everything is good, I've checked it all. I've checked manifold temps with a temp gun, pulled the valve covers and unplugged each injector to make sure they all were working. Found a bad one, it had a broke armature screw, I replaced the screw and injector started working again. Idled smoother...

Oil level is good, batteries and cables are less than 2 months old. TS chip, 3" dp 4" straight pipe tymar intake. It acts the same with the chip on stock or turned up. Fuel filter has about 30 miles on it.

My psd keeps cutting out at higher rpms, around 1800 and up. It cuts out and drops a few hundred rpms then picks back up. It does it constantly. It did this once before and I put a new CPS in it and it ran fine but this time I've put 2 in it and it didn't fix it. Fuel pressure is fine.
