The fuel pump has to build up pressure, that may affect the startup.
In my '96, I never did this nor did I ever have a problem with it starting within 2-3 cranks. In fact, I could never hear the quiet "whir" of the pump priming the line.
In my '07, it makes a difference. If I do not prime the pump, it will still fire off in a crank or two, but it then stumbles for a moment before steadying. When I prime, it starts just as fast with no stumble. I can hear the "whir" on this one as well. It lasts about 2 seconds, so I put the key to "on," put on my seatbelt, then start it.
Spark plug wires would be the next thing to try. After that, the ignition coil.

after that, you've covered most of the things that are involved with cold vs. hot start...

Thank you all for these suggestions, I'll let you know of the results.
Keep in mind I'd swap out the spark plug wires after (at most) 60k miles anyway. They do wear.
On my Miata I only get 30k miles from a set.
Intake 0.10 - 0.25
Exhaust 0.15 - 0.30
Seems a wide range of values .... anyone noticed this or have you checked (for any reason) the valve settings on this engine in your vehicle? Larry.
Remove the ash tray assembly -- there are a couple screws, one is way in the back. Unplug the light.
Remove any screws holding the fake wood trim panel. Then you can remove this piece from the dash, giving access to the radio stack.
Good luck!

Basically, you want the lash at the minimum specification to reduce noise. At some point beyond 60k miles (perhaps 100k), a normal car should have it checked and set.
Are you hearing excessive valvetrain noise, or were you just curious after having the work done?
~Colin
I am going to have them 'loosen' the clearance and see if this is the problem. Any other insights are appreciated! Larry.
What exactly happened to necessitate valve replacement? I think you said before that only the valves were replaced, which if literally true could potentially explain a loss of power.
A single overhead-cam engine cannot foul the valves on themselves because as the name indicates, only one camshaft drives both intake and exhaust valves. So what did the valves hit? Either water or one or more pistons, which may have-- probably did-- damage the piston tops to some extent, and possibly connecting rods. Low chance of crankshaft damage as it's the strongest component by far, so everything else tends to give. 'Everything else' also includes the camshaft, when valves hit each other or a piston you can flatten a cam lobe or even twist/break the camshaft.
Sorry to paint a grim portrait, but I just have a very hard time believing that a complete repair could be done only by replacing valves. I hope that's not the case...

thanks for response ..
Interestingly, my '98 has an access panel and you go from the inside of the car to do this.
On the 03, you actually remove the taillight. Two 10mm bolts hold it in place, once you remove those you pull the entire taillight assembly away from the car, it has 3 snaps and it sort of "pops" out of place. Don't pull too hard, because the wires are still connected.
Changed the bulb in no time, and then reversed the process.
Just found it funny that the 1998 and 2003 models are entirely different in this regard. :confuse:
Buy a box of baking soda and keep that in the cargo area. In fact do that all the time, regardless.
A small Rubbermaid "Rough Tote" works wonders for storing emergency/maintenance equipment in the back of the car. It is spill proof, portable, and compact - for next time, anyway.
It seemed to seal well, the area wasn't dirty at all. So it works.

I have the Chilton's manual for the Miata and let me say, IT STINKS!
It's so useless that I don't embark on *any* project without getting a 2nd set of instructions from another source, usually on-line.
The amount of help for even a simple brake job was rather pathetic.
You do get what you pay for. :sick:

Subaru apparently wishes to discourage owner maintenance, a pity!
There is very little maintenance that needs to be done on these cars, so I'm not sure why you think they are discouraging owner maintenance.
-mike
Any deeper than that and they want you to come in for service with their trained mechanics, naturally. We pay below invoice for cars so this is the only way they can make money and stay in business!
Although I don't expect the Impreza to require more than fluid changes in the near future, eventually there will be routine maintenance for which a munual is useful, e.g. brake maintenance, timing belt changes, etc., even if one never messes with "engine internals". And there is always the possibility of failure, however remote, that would leave you at the mercy of dealer service (I expect to own the car much longer than the warranty).
Lastly, I like to become familiar with any machine that I own, particulary one such as the Subaru that is different in many ways from my previous vehicles, and I know of no better source than a shop manual.
Well in this day and age, the "dial-up" excuse doesn't hold water, it is 2007! Eventually if you like it or not you'll need to come into the computer age, I'm not trying to be harsh, but it's just a reality. What I did was downloaded all the sections I thought I would need in that 72hr period, then I have them on my computer. Simply print out the pages you want to use and take em to the garage with you. One of the distinct advantages is that you can take it under the car with you and get it all dirty, and throw it out when you are done!

"Get on board the technology train, or it'll knock you down!"
I will agree with you regarding the Chilton manuals, but my experience with a Haynes manual for my '96 Outback was very positive. Considering all the work I did on that car, there were only a couple times that I had to fumble through something because it was unknown to me and was not covered in detail. I had no complaints, and neither did the car (after it was repaired, that is!).
I hear ya there. If you can believe it, there is no option other than dial-up at my location other than the option mentioned below, which is prohibitively expensive. I do have a decent connection at work, so admittedly I use the connection to my advantage from time to time.
I have some friends who live in the wilderness along the Yukon River near Ruby, and they have something called "Star Band." Spendy, but it puts them in contact with the world whereas otherwise their nearest neighbor is about 7 miles downriver!
