Default Hard starting

On my 89 SSE I've started to expierence a new problem--started a few weeks ago.
If the car sits for longer then a day it'* hard to start. The 1st time it happened I pulled the plugs after cranking for awhile-and the plugs were wet(flooding)-so I dried them and let the car sit for awhile-tried to start again w/the same situation resulting(wet plugs)wasn't even hitting the gas. So I got pissed and just kept cranking it(long time)--it finally started!! I'm thinking it'* the injectors sticking open that'* causing the problem(fuel pooling in the intake). Isn't the fuel pump because there'* no loss of power at all. I only expierence this problem when the car sits for longer then a day.
Does this sound about right?
Also--what would be the best way to fix this--other then replacing the injectors.
Anyone know what the injectors are rated at(lbs)?

First are you sure each cylinder is getting spark? If so then maybe it'* time to rebuild those injectors. New ones are very expensive, rebuilding or at least cleaning them is a better way to go. You can test your theory though by pulling an injector & placing it in a container while still attached to the fuel line. This way when the vehicle tries to start that injector should open & close.

You might want to just pull all of them and let them sit on the manifold for a day or two after the rail has been pressurized to see if any drooled.

Each cylinder is getting spark-I just replaced the coil pack w/a known good one(tested).
How would I go about pulling the injectors out of the intake while leaving them attached to the fuel rail pressurized? since it is a hard metal line--w/my luck I'd break it!

I'm not sure how much different yours is than mine, but on mine, I pull 3 bolts on the rail, and lift the whole thing. They all come out together sortof. Just be careful. Have some new O-rings handy, too.

To be honest-I just checked the 3 outward spark plugs and they were all wet--and loose to! When I replaced the coil pack I also changed the module(both parts didn't even have to be changed either).
Car isn't throwing any codes for the engine-just some trans code--That was the 1st thing that I had checked. It'* hard to tell exactly what my mileage is because my speedo is off due to 225 size tires on it(stock is 215) I never thought that it was that great on gas tho(have a heavy foot!!)-did a tuneup on it less then a yr ago--just to be sure.
When you say pcm-do you mean the ecm? I was thinking of swapping that out anyway--but wouldn't a bad one throw a code too?
Other then the starting problem the car runs excellent--lots of top end power and low end grunt.
BTW--I smelled my oil and it smells like gas--not alot but the smell is there.
Now I'm sorry for rambling!

DAMN!! 30-31 mpg?? That would really help me out! I fill up every day and it costs me $14-$15 a day! Adds up!
Funny--on my ecm someone wrote on it that it was for testing purposes only--don't use--guess there'* something to that then! In a yard I go to there'* a 90-91 that I need to get a seat rail from(mine broke)and I was debating on getting the ecm--now I'll get it. Any other model ecm'* would work? like Lesabre'* etc?
My computer was down for almost 2 months--thank God I have it back!
I Missed this site!

Yep! I'm about due for my oil change--it isn't too thin(checked that out)but due none the less.
I'll check out that ecm--always wondered about that writing on it.
might be better off getting the re-man like you said.
Think the prom would be bad too? do they also go bad?
i was thinking the one trans code I was getting was because of the different size tires on it(tcc not locking up--that may be the cause of the poor mileage too--forgot about that) think that'* possible--tire size difference?
Thanks for all the help!

Cool--I'll let you know for sure.
I thought the same about the tires--but I was told the 225 is a taller height then the 215 tires--so it throws off the speedo--the faster I go the farther it gets thrown off.
when the speedo says I'm doing 85-I think I'm doing 95.
I can't complain too much about the car tho--bought it from a junkyard w/a new paint job and 4 brand new tires w/around 8x,xxx miles on it--all for $2200 US -almost 2 yrs ago! Had an almost mint interior too!

Yep-they say 225/60-16
I think they throw off the speedo somewhat tho--can we get someone else to confirm?
