2004.5 lly
Recent head studs and gaskets
Start it back up prime the system
Barley running
No pedal
Low oil pressure light on
And low fuel rail

Checked all connectors check to make sure gaskets are on correct
Have plenty of compression. Which none of this would explain the no pedal

When you clear codes with it running knocks hard then back to doing the above

Got your grounds hooked up?

Sure do

Did you notice if any of the pins in the bale connectors were pushed back a little too far?

Didn't really notice but going to go through harness again tomorrow if if anything comes up

All the fluids where they should be? try disconnecting the FPR connector and see if rail maxes out. Does it have low oil PSI or just the light?

Just the light and gauge. Fluids are all up to par and will do in the morning just so weird bc there all very different things going wrong

A bunch of random stuff not related is a ground most of the time. When my engine to body ground wasn't tight I had all sorts of random issues, like MAF, ABS, etc going on

 

[Mpsoldier]

I just check the grounds but will do again

If you pull the connector off the FPR and it builds rail fine I would pull and clean all grounds, then start tracing wires and connectors.

Alright so unplugged fpr started up fine but knocking like crazy

Also still no throttle

Did it max out the rail PSI or is it still low?

 

[adeso]

sure you didn't mix up injector harnesses somehow?

It maxed it out and I don't see how I can mix up harness for injectors i don't take the whole harness off just unhook the ficm and fold everything over off the front

 

[Mpsoldier]

I don't think you physically can put the harness on backwards

 

[adeso]

yea you would have to really jack something up to do that. Since it builds rail with it off I would say it is electrical. Just a PITA of checking everything again. Sorry I'm not more help, I'm kind of guessing right now

Thanks I have never ran into something like this before so weird really the no pedal has got me thinking along the lines of ECM probably test it tomorrow to the only ground unhooked it the one to the hood

Check fuel temp sensor (that its plugged in)
Check FICM plug
Check engine grounds

You can also have no pedal if you left the MAF sensor unplugged.
