no power NO SMOKE
Ok my brother just got a 93 w250 and it is really slow. Please dont flame me for looking for smoke because that is not the goal. I opened the afc and turned the star wheel 1 and 1/2 turns and the fuel pen doesnt look stock because it is a symetric cone and doesnt have a steep side but it doesnt look performance either because it is not all that steep and it has #70 on the bottom. fuel linkage is pulling throtle all the way. No boost leaks as far as I can tell ( I put soapy water on the boots and afc). He doesnt have gauges yet so I have no clue what boost and egt's are at. I was just expecting this to bring this truck alive and it diddnt. What sould I check next Also it is all stock so it still has the muffler and fram filter
AGAIN THIS IS NOT A MAKE MY TRUCK ROAL COAL THREAD I WAS JUST EXPECTING A LITTLE MORE FUEL |
I would start by checking fuel pressure and go from there.
|
That's what I was gona do what should it be at
|
Should be 18-24 psi at idle, 28-36 psi at 2000 RPM with no load.
|
With stock lift pump fuel psi is between 4-6psi on a 1st gen.
|
What about 2000 rpm
|
About 2psi. under a load. the ic trucks are dogs from factory. cut the muffler out n crank the fuel screw but don't forget to be carefull of rinaway
|
are you talking about the smoke screw cause I made it even with the lock nut and I also cranked the starwheel. Im also gona throw my denny t #2 at and see what happens
|
Fuel screw, not smoke screw. Fuel screw can cause runaway, smoke screw can cause low boost smoke.
