step 1-take off valve cover, intake horn, and tps
step 2- now that you have full access to the injector lines, take off the line holders and take off the lines, some find it easier to do the injectors in 3's but i usually do them all at once.
step 3- now the all the lines are out of the way, use a flathead screw driver and pry the crossover tubes out 1 at a time be careful not top strip the threads, if you loke lopey idles get the tubes drilled out.
step 4- clean your IAT "intake air sensor" located on the back of the plenum just ahead of the MAP sensor closer to the firewall, trust me you will thank me later it takes 10 mins and if you want your truck to run smooth and not stall with the new injectors its a MUST.
step 5- when i do injectors i do a full valve adjustment also, so now we are gonna take out the injector, take off the exhaust rocker "the bigger one" on each of the cylinders 1 at a time as you go, now with that out of the way there is a circular looking piece of metal between the rockers "your injector is under this", take out both bolts and get it out of the way.
step 6- yayy you can see the top of your injector right???? you should!!! but how are you gonna get it out hahaha, ILL TELL YOU, take one of your valve cover bolts and it will screw perfectly into your injector, now simply pull it out, if it doesnt come out make sure your connector tube is out.
step 7- if you are putting nozzles on, look at your injector there is a bolt on the tip, put in a vice and loosin it, now move injector to a open table and take bolt off completely the nozzle will come off along with a couple of other really small parts HENCE THE OPEN TABLE LOL!! put back together as they came out, i dont get them pop tested and its worked fine for me but you can do what you want with your injectors.
step 8- putting them in can take longer then taking them out, so please be patient, get a dab of vasaline and put it on the copper washer and then put it on the injector so it sticks "this is my easy way to get them in the 5th and 6th hole" lol other wise nits a pain in the a$$.
step 9- make sure you line the whole up on the injector with the connecting tube hole, put the injector in the hole put the injector cover on and torq it down "idk the specs like 75 inch pounds or something" now put the tube in you gonna want it to snap in place and it needs to be flush with the head just as it came out.
step 10- get everything put on and back together, make sure all the lines are tight as hell on the pump DO NOT SCREW THEM ALL THE WAY IN ON THE TOP YET WE HAVE TO BLEED THE LINES, ok get everything put on leave the intake horn off and now turn the motor over until shooting fuel out then screw them tight!!! you might have to do this a couple of times.
step 11- your truck should be running now, if it ever stalls on you randomly you didnt clean the IAT or you have to bleed lines #1 and #3 and it will fire right up.
