I doubt it has anything to do with it, unless you find a huge puddle of fuel there along with it gushing out when you turn the fuel pump on. Sounds like a separate problem and you'll need to replace the o-rings on the injectors. They're easy to do, just unbolt fuel rail, pop 4 injectors out, replace o rings. While you're at it, might as well have them tested and cleaned. Not sure where you live, but there's lots of places that do them, although my preference is:
Fuel Injector Cleaning
I've had them do 5 sets of injectors now, they always do a fantastic job, send you a whole bunch of info for each injector and give you the full specs on before/after. They will also replace those o rings and bottom rubber seals too.
At this point, your plugs should be swimming in fuel! If they're not completely soaking wet, you definitely don't have fuel coming out of the injectors. I have never heard of all 4 injectors dying at once, and unless you sucked up a ton of rust and crap from the fuel tank, AND that all made it past the fuel filter, AND it got to all the injectors spaced evenly enough to clog the screens, AND it went past the screens and plugged the pintle inside the injector, you are simply not getting the injectors to open up and shoot fuel.
Pull the rail off, turn the pump on by having key in on ignition, not started, stick your finger inside the MAF and open the door slightly, the pump will turn on (or you can jump the connections in the test cable, your choice, its easier for me to stick my finger in the maf door, more control too when it starts flowing).
Flow a bunch of fuel out of the rail, try to catch it with a bucket or something (I'm being "eco friendly" here, in case some tree huggers are reading!
) Let it flow for about 10 seconds and see if the flow shuts off or slows down. If not, then let everything dry off. get multimeter and check at the injector's wiring connector, see if you have proper voltage and test for ground on the other side of the wire when starting (you'll need two people for this).
Its either flow of fuel or electrical not opening injectors, that's all it can be at this point.
