This is probably like my 5th thread started on this issue. No one so far has been able to help me. Im kinda looking for shoebox or injuneer to chime in. My car wont rev past 3500 rpm. It is a fuel problem. it drops to 0 at 3500 rpm. I have replaced the fuel pump and the fuel filter. The lines dont seem to be bent. It idles fine, but like i said i cant rev it past 3500. I really need help on this!

 

You your check injector fuse?

 

yes they are both ok. No SES lights

 

WHat happens when you attempt to rev it over 3.5K? Does it sound like your engine is stalling out?

 

the pedal feels dead like it is getting no fuel.

 

Mine is doing the exact same thing right now but it goes to 4500 in 2nd and 3500 in 3rd and no higher.

 

I see, but does the motor start breaking up?

 

Maybe its spark related? Coil perhaps?

 

Sounds to me like you have a clogged catalytic converter.

 

The exhaust i run is headers, NO CATS, and a bullet muffler.

 

I vote for ignition... I think if your car was starving of fuel.. on a high RPM... the engien would bog and stall. I've gotton the same dead pedal feel from having a fault in my ignition system. I couldn't get over 4.5 RPMS

 

Ignition is all good. when engine starts to get the dead pedal, and i have someone spray brake cleaner in the intake the rpms rise.

 

Well get a fuel pressure gauge on it and see if its your fuel.

 

id you check FP? where is it at?

 

It is normal except while in park, or under load when u rev past 3.5k the Fuel psi drops to 0. when u release and to back to idle it returns to normal.
