It really only takes, spark, fuel and compression. Combined with the proper timing of a spark.

You aren't holding the pedal to the floor are you?
Negative on holding the pedal down. I don't think the injectors are firing, but I will confirm that today. If they're not, other than the injector fuse and pcm, what is involved in firing the injectors? Anyone have an FSM flowchart?

Brandon, I don't want to keep harping on this and don't want to imply this is your problem, but the o'ring you removed bothers me (so I guess I will harp on it, lol).
Do you think there'* a possibility that you may have left the old o'ring in there and that was interfering with the new install?

Wow...GREAT idea Mike... (private joke )

I've got the books at home... Have you considered pulling the airbox out and using carb cleaner or a spray bottle w/fuel to test your theory?

(Warning....this could be dangerous or very cool...)

I'll concede that the FPR thing may be an issue, BUT when I could plainly see 50PSI while cranking the engine, shouldn't it at least TRY to start if I have spark and the injectors are firing? I realize it bleeds down quickly when the pump isn't running. I don't even think there WAS an old o-ring where this one goes; I never saw it. It'* not the 3/4" or so one that goes around the body of the FPR, but a small 1/4" or less o-ring that goes around the center post of the FPR. There'* a little indention that it looks like it could fit into in the FPR cup, but it definitely doesn't want to go together that way.

Well, I did squirt some starting fluid in through the TB, and it still didn't try to start. That doesn't exactly help my theory, now does it?

I'll still bet a dollar the the injectors aren't firing, so I'll be picking up a noid light kit today to find out.

Can you get some pics of the noid...

I've heard about this and all I can think of is the Dominos Noid....lol Never seen the way to check injectors with a light.

You can buy the whole kit just about anywhere for less than $20. I've been meaning to buy some, and now I have a good reason to!

If your getting spark, and fuel and your pressure is at 50PSI while cranking, and it still wont start spraying gas up the hose and your FPR is new could it be the timing belt? Nothing starts with a bad timing belt.

I would think that'* a possibility. I'll a) do a compression test, b) use the noid light to test the injectors, and c) pull a valve cover, and look at the valvetrain - you know, make sure the valves are opening and closing!

How many miles on this car?

The 3800'* actually have gears and a chain, which is not very prone to breaking like the typical belts.
