I made a post quite a bit ago about my 97 and possibly diagnosing a bad ecm/pcm. I was able to drive it around a little while longer with what it was doing (previous post for reference) it was the ecm as I found out the hard way after replacing my torque converter clutch solenoid. Well new one is in the truck. Took it for a drive and there’s so much more power it’s stupid, well I broke my tires free in accident and when I let off the truck just died after about 300ft of driving I’m guessing. We’ll now just no spark all around. Before replacing my computer I replaced my pick up coil (camshaft positioning sensor) crank position sensor, cap and rotor along with the coil itself in hope that was it. I have no spark from the coil itself or cap to plug. Any help would be appreciated thank you in advance.

 

forgot to add this but it has been running just fine the last few days. Starts up, idles just fine and has perfect throttle response. Today was the first drive since the new solenoid and ecm, but as soon as it broke free suddenly it’s done again? Not to mention I had grabbed two ecms. One for a standard (as I’m putting a 5 speed in witching the next few months) the other for an auto, both from a 97 with a 5.9. The auto will let it start but won’t stay running and won’t read the rpm’s, the standard will let it run and goes into gear just fine. As well as the standard looks identicle to the previous one in my truck

 

The PCM's are the same, it's the programming that's different.

How does your throttle body look? Kinda grimy in the back??
