so i just got a new fuel injection system for my 95 blazer,, wanna do it myself but not to sure if i can, or how.. does anyone have any tips, or if there's photos out there?? any help would be killer!!! thanx

 

If you are wanting to simply replace part for part then a good shop manual and/or thread search will help immensely. If you are talking about changing over to a completely different type of fuel injection system then that's a whole other can of worms...

 

Removal and instillation is pretty straightforward with the fuel lines being the most difficult to remove/reinstall on some model years. Such as my 2000 s-10 where the lines are one solid unit all the way from the spider unit to the back of the truck. Hopefully yours will separate at the mounting bracket like my 01 blazer instead.

The #1 tip for this job though is to immediately plug all your intake ports with a shop rag as soon as they are accessible. You could very much regret it if you do not do so.
The very first time I did one of these I didn't do so right away and dropped an aluminum nut down into an intake port and had to remove the lower intake as well to retrieve it.

 

thank you all!!! success!! i did it last weekend,, it was just the spider set up that i changed. got a haynes guide, and bout 3 1/2 hours it was done... i didnt follow your warning bout covering the ports, aaannnddddd, dropped the clip for the gas lines in one of them.. thank the lord my father-in-law came with a trusty magnet snake, and i hooked it..... totally releaved. N.E.way it runs great, even better then before, check engine light is no more, and its got alot more umpff ta boot!! thanks again for all the help!

 

Just be glad you didn't drop an aluminum (non-magnetic) intake nut down there... it's happened to alot of us.
Glad you got it fixed!

 

where did yo buy your spider from? was it new or remanufactured? and how much did it cost? just curious, what was your truck doing wrong before you changed the spider? thanks so much

 

i got it online at this place car junky.. it was like 220, thats with shipping and a stupid core charge of 40. i was told an aftermarket part wouldnt be smart, and the OEM parts is like 300 something, so this one is a rebuilt. anyway i was having problems with it starting, then it would glug for a bit til it was warm. i was getting EGR codes. it was just running like crap, no pick up, nothing. then it wouldnt start at all, till i primed the fuel pump like 3-4 times. my mechanic said the spider was leaking fuel and flooding it out.. sure as anything when i took it out, the whole side was washed clean. it only took a lil while, not a bad saturday afternoon project. its runnig great now...
