You probably have a plugged fuel pump or filter, or a possible bad pressure regulator that is located on your fuel rail. I found this info in another Awsome Furom. I hope it helps you out. INJECTORS The following is a list of the injectors used on the 4.0L since 1987 along with their rated static flow: Model Year Part Number Color Fuel Pressure Static Flow 1987-1990 53003956 Black 39psi 18.6lb/hr 1991-1993 33007127 Brown 39psi 21.0lb/hr 1994-1995 53030343 Tan 39psi 21.0lb/hr 1996-1999 53030778 Grey 49psi 23.2lb/hr 1999-2006 04854181 Blue Tip 49psi 22.5lb/hr The injector flow rate varies as the square root of the pressure drop across the injector. The stock '91-'95 4.0 injectors are rated at 22lb/hr @ 43psi fuel pressure, so at 39psi they flow ( sq. rt.(39/43) x 22.0 = 21.0 ). For stock/modified 4.0 engines or stroker build-ups the following injectors can be installed. The flow rates are: Ford Motorsport 19.0lb/hr @ 39psi (Part no. FMS-M9593-C302) Ford Motorsport 24.0lb/hr @ 39psi (Part no. FMS-M9593-A302) Ford Motorsport 30.0lb/hr @ 39psi (Part no. FMS-M9593-B302) Chevy LT1 24.0lb/hr @ 43.5psi (Part no. 17124248) Chevy LT4 28.0lb/hr @ 43.5psi (Part no. 17124251) Accel 19.2lb/hr @ 44.1psi (ACC-150119) Accel 21.1lb/hr @ 44.1psi (ACC-150121) Accel 24.4lb/hr @ 44.1psi (ACC-150124) Accel 25.6lb/hr @ 44.1psi (ACC-150126) Accel 29.4lb/hr @ 44.1psi (ACC-150130) The '95 Jeep 5.2 ZJ/Dodge 5.9 injectors (Part no. 53030262) are rated to flow 24.6lb/hr at 39psi. The selection of injector size will depend on the estimated horsepower output, brake specific fuel consumption BSFC (assume 0.5), no. of cylinders, and the injector duty cycle (assume 80% or 0.8). The formula is: Injector size (lb/hr) = (horsepower x 0.5)/(no.of cylinders x 0.8)
How much fuel pressure in a 2001 dodge ram 1500?
spec is 49psi plus or minus 5
95 dodge neon that spits and sputters going down the road cant get over 30 miles an hour you have noticed that after taking a corner it stops for awhile but when you slow down it starts up again?
Was totally incorrect, and removed by original poster. j3h. Neons are fuel injected. Check your fuel pressure, it should be around 49psi. If it is low, I would suspect a clogged fuel filter, or possibly a fuel pump going bad.
