can anyone tell me the fuel flow? i was going to try and take a fuel pressure reading at the pressure regulator . i figured that the fuel was coming in from the passenger side into the regulator and then out the regulator on the drivers side into the throttle body. however when i pulled the large hose off the passenger side of the regulator the fuel came out of the regultor some i am assuming its coming in to the regulator on the drivers side in the small hose and the larger fual line is a return line?

scratch that i figured it out (comes in via the hard line on the firewall side of the throttle body

had the same problem after doing my swap ended up being a fuel issue replaced the injector and filter runs great now I have the 8v the injector is cake to replace!

Hmm - nobody has suggested the throttle position sensor yet?

TBI engine only uses the TPS to tell
the computer that the throttle is opened,
or at WOT ect.  The trucklet will run without
a TPS, just with a little hesitation, but won't
bog down like the symptoms here.

I drove with my TPS pulled once, just to see
if it was bad or  The MAP seems to give
the computer the bulk of it's info, that and the
O2 sensor

well what i am thinking now is this... im gonna tap into the o2 sensor and try and get a reading with the volt meter that tells me roughly if i am running rich or lean... the theory is this. if when it starts bogging down it goes super lean that will tell lme that its the fuel delivery system either pump or regulator...or possibly injector... if it goes super rich it will need to be in the exhaust side due to backpressure from the cat manifold  etc keeping the cylinders from emptying out and pulling in fresh air...

thoughts?

You would need an air-fuel ratio
guage to do this accurately.

What is the fuel PSI ? check it yet ?

I don't know if the O2 will tell you if
the cat is bad, I don't think it will show
rich, but a reading of the back pressure
would tell you if the cat is plugged

i havent been able to check the fuell pressure since ihavent came up with  good way to tap into the fuel. also i dont know how to check the back pressure.

as for reading off the o2. based on how bad the rig is running it should swing more than enough to the lean side (less than .5volts) for me to be able to see it

  ,  Go check your fuel pressure,
cut the soft line in half with a knife,
put in a barbed T and clamp the hoses,
put on a cheep $4 pressure guage
from the hardware store and check it.

When you are finished use a straight barb
fitting to fix the cut line, I have had this done
for 3 years now, no leaks, like I said, it's only
36 PSI and your symptoms are classic low fuel PSI

You are going to jack around with this for weeks
and the simple thing is usually the fix

wild which soft line are you talking about ... back by the fuel filter or up front at the high pressure line right before it goes into the throttle body

hmm insert curse words here...

well i cut the fuel line right after the fuel filter and then ran a lone though a hole in the floorboard up to the dash with my guage... low and behold today i cant get it to do it....so when i first started the rig up i have 40psi... if after driving it about 20 minutes i can get it to drop to about 22psi but again i cant get it too bog down miss etc. but as i said if i really hammer it i can get the pressure to drop down to just above 20 psi... so what do ya think?

wild which soft line are you talking about ... back by the fuel filter or up front at the high pressure line right before it goes into the throttle body

I was talking about the one in the front,
but either will do, the pressure drop would
indicate a weak fuel pump or bad/plugged filter,
but since you changed the filter, I don't think that
is it, you did change the filter right  

I think you should replace the pump, you can
use a bosch external pump, and it will bolt in
the the banjo fittings at the filter if you do it
right, I added a bosch pump when I needed to
boost fuel pressure, I ran both pumps from the
same power feed, you could do the same, and
a used wrecking yard pump would be much less
than the new unit which I hear are about $100

I got a similar problem with my 94 tracker.... first gear is fine all the way to the floor, when I hit second, it bogs bigtime when I get on it.... (manual tranny) but when I let off it pics back up again, all other gears are normal, just happens in second, but it clears all up after it warms up for a bit. Im thinkin its the cat cause I hear crap bangin around in there.

loose cat material will cause many different headaches.  rattling around, boggs you down uphill, bogs all the time.   I would really check that first.  but keep the fuel pressure hooked up, wont hurt a thing, I have one permanently on my motorcycle after I had fuel filter issues.

yup i changed the fuel filter. when i started all of this . i think im gonna try and drive it around for a day or two and see what shows up on the pressure.
