Default Canister purge solenoid=help

I am having problems with my 1988 olds cutlass FWD 2.8 v6 . I have tested & replaced some bad parts on the engine. I did verify they were bad prior to replacing . Lastly I have just bought a new canister purge solenoid.The old one when tested with a hand held vacumn pump- showed a slow leakdown! (off engine) I tested -same way the new sol. & it will not hold any vacumn at all-like maybe it needs to be installed & a signal from ecm ? makes it work?? Now -- i also need to know where the 2 vacumn lines go to from that connect to this solenoid. 1 line i believe goes to the rubber connector thats on top of the intake manifold.pretty sure of that -yet?? where does the other go to?? that line is NOT shown=on my vacuum diagram. Help!! This car is a OBD! cant remember the code tossed (1 only) yet it will start fine -idle great (normally) and then dies when i try & accelerate. I have again replaced some parts =TPS & reset all values & tested correctly! I have verified tps .5v reference & ground & it works as should with no dead spots & increases voltage as should -its not the TPS!

If I remember correct in 88 you could get the 2.8 in a port injected motor or it had a throttle body injection. Witch is yours? Maybe someone on here has a Alldata account that can help with the vacuum routing.

one goes to the canister in the rear of the vehicle the other to the throttle body. if there was a TBI it was likely the rwd one, i think both were available in 88. i had a 88 fwd and it was the mpfi engine.

Forgot to mention, the new one should hold vacuum. Not sure if it should be with voltage or without but if you put your tool on the tube going to the tb one way it should hold vacuum, and the other be open

Default FWD 2.8 engine

im now discovering I can not locate the vacumn line that comes from (i have that line) the intake rubber connector TBI multi port injection 2.8 engine--) to the HVAC/ Cruise line-where is this hvac line located? I find the cruise & lines hooked up there yet there is no spare vac line near firewall area to hook intake line too??

ok here=jwfirebird---- see on the diagram you supplied=Thanx by the way- the line that goes to "HVAC" ? i cannot locate where that line connects too? Im guessing to a Firewall area?? yet none found. I just cant find where that plastic vac line coming from intake goes to.?? I have that port currently blocked off @ intake. Cat starts / runs (havent driven) yet tosses code 34- low map?? Map repleced with a new one -same code?? as i look @ what the code means?? relates to high vacumn?? what the heck? Also the heater controlls do not work-likely due to the HVAC not being hooked up. All work on this car has been done by me & hvac always worked before. Thanx.

the diagrams are sort of just for function, there could be a line to the cruise actuator and then a tee that goes to the hvac. could also be a line that goes to the map then the hvac or cruise. also if you are using the old hoses it may be leaking, old hoses always leak after you disturb them. its a good idea to just get a bulk roll of the different sizes and just replace it all at once then you dont chase phantom issues forever. i personally would just hookup new lines to everything the way it is on the diagram and that should make it all work

You are totally =Correct! Lines & such! now- i have started this car up 2-3 times- having started car up 2-3 times & allowing to idle for over 1 hour each time -i noticed today= when i turn on the heater- the engine dies!! and then trips a 34 code then. no codes before that time. I do have that line from cruise area (appears to go to canister) (like a 3/19 or 1/4 " plastic line hooked to the canister purge sol. (replaced new) -- Yet still unable to locate any other lines that woild be open & available. Ill also say - when i shut the engine off- with hood open - i do hear a vacumn sound (again=engine off) coming from that same area below= the cruise actuator-yet not the actual actuator. like in the canister area & i cannot see that as its below the battery area. ????? Still no HVAC controlls are operational. Its also very hard to start initially when cold! Temp sender bad?? a guess?
