95 dodge 12 valve would the fuel shut off solenoid cause you to have no power if it was real bad. truck has no throttle response when cold but after it warms up runs fine all filters are new and we replace the solinoid because it fell apart in 3 peices

 

If its not adjusted right it would be screwed up all the time me thinks.Do you have guages? hows boost look? Does it run OK on start up? smoke etc?

 

no gauges smokes alot on start up runs ok on start up you just cant go untill
it warms up if you try to floor it in neutral it misses alittle and will not rev up past 1500 to 2000 but once warms up seems to run ok

 

Your fuel pressure could be too low.
You can make a set up to check the pressure or for about the same amount of money replace the overflow valve.
You won't find a better price than here

Those symptoms are also indicative of retarded timing.

 

my brothers truck is doing same thing(96") it misses bad for about 5-10 minutes till you blow it out he says! then it is fine people is telling him sounds like injectors (they work better when they get warm!loosin up some)
keep us posted.

 

I would also agree if hasn't been checked in a while.

 

My truck is doing the exact same thing..... Takes 10 minutes to warm up. Will spit and sputter until it gets warm. And TONS of white smoke. I noticed tonight that my fuel shut solenoid is not lifting when I start it. And I think my grid heaters and grid solenoids are not working either....

 

I took my heater out and when its below 50* outside it sputters for about 30 sec then settles right out above 50* it doesnt sputter at all.
