Thanks for the inputs... I'll give the fuel pump diagnotics idea a try, but mainly cause I feel if it were MAF, o2 sensor, ignition coil or ignitor, the car would stay level at the same RPM.. but I'm sure I don't know what I'm talking about here... all I can do is apply logic to my thought process as I lack mechanical expertise.

I keep hearing the fuel tank is in the trunk, and I've also heard it's accessible from the trunk... in this img, what is the thing in the hole, covered by the small plate w/ 3 screws? I've got two plugs to it... so I thought it has better chance of being a pump than a filter... but for all I know, it could just be the float sensor..

Finally, when I try that diag trick... is it safe to just plug the paper clip directly? or do I need to unplug the battery, connect, replug to test and then d/c battery before I remove pin? Tho, I guess I shouldn't ask at all as it's never wrong to be safe and cautious... Also, how will I know if there's fuel flowing or not? I doubt I'll see anything, I can't even visually find my fuel rail yet even.. should I be hearing the gas flowing? or is this something I have to pull a line and drop into a bucket for?
