I’m hoping I’m skipping over something simple but I’ve never had an issue like this before. The truck is an 2001, Firepunk 47RE, 6x.018, s475/87/.90, MVP-TST Comp, Fass150
I just finished up converting the transmission to a full manual valve body with a ratchet shifter. The truck wasn’t doing this before i did the FMVB. I believe the gov. pressure solenoid was on its way out and was planning on a FMVB anyway since the truck is only unused for sled pulling and not often street driven..
The first time I test drove it everything was fine but a few miles down the road it got a dead pedal only at 2000rpm. Truck felt and sounded normal but as soon as it would hit 2000rpm t would just stop. It did this for 5-10 seconds and cleared itself up? Got to where I was going and an hour later headed back to the garage and it did it again, 5-10 seconds of dead pedal over 2000rpm then ran fine? The truck sat for around 6-7 hours then drove it- same thing again. Went to drive the truck back to my house and the whole way home it was dead pedal over 2000rpm. And it’s never ran over 2k since. Lock the converter under 2000rpm and fuels hard but hit 2k and it stops dead in its tracks?
-I only was running 3 wires to the trans- 12v, TCC ground, and OD ground. I added all the other wiring back into the plug thinking that maybe the PCM was seeing a major issue in the trans and tellling the ECM to cut fuel but that didn’t fix it.
-I checked codes and came up with P0253: VP fuel metering control “A” (rotor/cam/injector). There’s no CEL on and I believe this code has been there before. I cleared the code and drove it a few more times and the code hasn’t come back.
-Fuel pressure is solid at 19psi even when the issue occurs, measured on a mechanical gauge up near the VP
-I may try changing fuel filters to rule that out but seriously doubt that’s the issue, the ones on the truck now have 2k miles on them.
Is it possible torque managemt is causing this? I remember years ago having issues at 2k when brake boosting on the line in my old truck but a RadBox fixed that issue.
Other then that I’m not really sure what to do next. Everything was fine until after I did the FMVB. Sorry for the long post. Any help is appreciated at this point.
