Tools-wobble extension to get at nut under fpr-small ratchet wrench-magnet to find all the nuts you drop-1o and 12mm socket-philips head screw driver for gas line(gas cap off)-eye protection

Is this a good time to be smoking? hmmm(UNDO GAS CAP FIRST IF YOUOPEN GAS LINE)

IntroYou may have leaking fuel injectors. To test them, unbolt the fuel rail from the intake manifold and pull off the entire assembly. Keep the fuel hoses still connected and don't remove any individual injectors. Also keep the electrical connectors on the injectors. With the assembly now away from the intake, turn the ignition key to the run position WITHOUT STARTING THE ENGINE. Now observe each injector to look for leaks. There should be no drips.

Getting it offNOTE: It is hard to get the nut under fuel pressure regulator. Also hard to put fuel rail back on because of the nut/bolt makes it hard to get injector in nearest fpr. injectors went in as i tightened bolts for fuel rail. injector nearest fpr goes in first. clean the insulators as the injector heads will be rubbing everywhere as you try to get injectors in. insulator is in hole not on injector when putting back. my injectors appeared to be pinching insulator as they went in but everything seems ok once nut(12mm under fpr) and bolts(two 12mm main nuts) are all tightened. good luck.

thank you, i am going to try this out... so will this confirm if I have leaky O rings or not? Do some damaged o rings leak under higher fuel pressure .. like at WOT?
