Stalling at 4,000 then 3,000 then 2,000-2,250= WHY

[MOTORHEAD]

its a 1992 GTP 3.4 dohc 5 SPEED

DONT KNOW WHY IT HAPPENS THIS WAY, just asking to see if u guys have any idea or not..


driving out, eveyrhtin was fine but not at ulimately power, can tell some fuel cut offs n bs.. all of sudden it stalled out when hitting 4K rpm... again again then stalls out at 3K rpm... it is decreasing the rpm to stall.. its very weird.. every time it stall, the harder to start up the car.. it wont start while moving, it has to be stopped to start even THO its in N as u apply on the clutch.. then now it wont able go higher than 2000-2250 rpm, other wise it will stall. so it works on 1st 2nd n 3rd at least its moving.

ANY IDEAS WHY??

OUR guess it would be one of fuel pump? gas filter? fuel regulator? or its fuel injectors???

if no- module? wiring?

if no then what the hell is wrong w it?

reply asap please.. any QQ too? will love to answr some QQ if thats necessary.. LMK.. thanks

Fuel system is my guess, pump or filter.

put a guage on the rail will tell you all

Not exactly. pressure is a good indicator, but you can have pressure without flow. I know this because my car has the pressure but no flow when you disconnect the rail and watch it.

which part of fuel rail to disconnect????
