Glad to help, Daryll!

Okay, guys. Here we go again with the unique 90 MY stuff. I see that there is a different part number for the cannister (almost double the price), but the valve is the same as other years:

Looks like it has the purge valve built into the top of the canister, unlike the 91 which has the purge valve in the tank, and the canister has no moving parts. Bummer.

Also, note there's a solenoid and a valve - solenoid under the plenum sometimes incorrectly gets called a valve.

Okay, thanks. I'll try to take a look at it first and confirm the part number on the original before ordering anything. It seems we have a few unique items on the 90 MY...........what a pain in the arse.

yes 90 is different, those pictures you posted are correct.

1990 Canister is up front under the left headlight

How much is it for 90?

Thanks Jeff, I was wondering about that and a lot easier to get to so that is a plus.

Yep the 91 Replacement I received over the weekend looks nothing like that. Great catch Craig and yet another in the only My 90 club. Just like the Air pump etc.

VetteMed,

Thanks for this post. Your timing is remarkable.
I have a 90 which has just started exhibiting similar symptoms.
When I used to turn the key, the engine would crank for a few seconds and then start running.
Now when I turn the key, the engine starts running instantly. There is no delay in firing up.
I noticed the difference but did not know why.

In reading some of the replys, you did not explicitly state that the replacement of the canister and purge valve cured the problem. Did it? Is your car back to cranking for a few seconds before starting?

I also see that the 91 MY charcoal canisters are mounted upside down. This leads to broken down charcoal in the lines and then subsequent disruption of purge valve operation.

Has anyone else seen this as a problem in the 90 MY?
Does anyone else have a 90 which fires as soon as the key is turned and what have they done to troubleshoot and remedy the problem.

Thanks in advance,
ZeeAreOne
