well a little more digging this week end reveled:
In the cold start circuit with coolant temp < 95F, cold start circuit should be enabled.
Test: remove fuses for Inj 1 & 2, Connect Fuel pressure gauge, Crank engine at least 2 sec. Pressure should drop off > 3lbs if cold start is working,( engine attempted to start during this time), This Passed. Run engine until coolant temp > 95F, ( does not take long here in Fla) Remove fuses for Inj. 1 & 2 and repeat test above, there should be no Pressure drop. This also passed. This tells me my cold start circuit is operating as expected. During the time i was warming the engine, there was noticable smoke from the exhaust pipes ( black, like it is running very rich).and BTW ECM is reporting a Lean condition error 44, SES comes on occasionally, but will go out after a few minutes)
Also ran Pressure tests to assure proper regulator operation,
Static pressure ( Ign on/Eng Off) Fail point is 40.5, i measured 42.
Passed, but just barely.
With engine running pressure drop off should be down around 36lbs. if regulator is ok. This also passed. But again just barely
All readings i attained seem to be on the marginal lower end, Having only had the car for less then 1 month i have yet to replace the Fuel filter, Tune up was done a 2 weeks ago. and cleared codes 22, 36, 44, 46.
I have also found that if i apply a little throttle as soon as the engine starts, the problem seems to be minimized ( no stutter etc). This all takes place with-in the first 5 - 10 seconds of startup.
I am strongly begining to suspect a vacuum leak some where, Just picked up a Vacuum gauge lastnight, but have yet tried it. I believe i have also found a disconnected vacuum line that i believe connects to the Vapor purge selenoid ( only one line connected now ) , so i have plugged that on off, it connects back up to a Tee, which feeds to the C.Cont, diaphram.
