spider injection
 

i have a 1995 blazer vin w i had to replace the fuel pressure regulater on my spider injecter and i hooked everything back up all the wires and everything tried starting it and its not getting any gas for some reason gots spark and all just not fuel but its getting fuel in the lines just not through the injecter could i have hooked the pressure regulater up wrong maybe cause it worked before i put the new one on thanks Chris

I would check the fuel pressure first. Unless you forgot to install the o-ring or left the old one in...it sounds like you may have damaged the wiring to injector. You didn't turn the screw on the end of the fuel pressure regulator did you you?

nope didnt turn the screw on the regulator um what o rings are you talking about the ones one the ends of the fuel lines that go to the injector?

There are two O rings on the fuel injector. One large one and a small one. When I replaced mine last week I had to dig the small one out with a small screwdriver. That might keep the regulator from seating correctly. Same if the large one stayed in the spider unit. Did you get both old O rings out when you took yours out?

im not sure of the o rings you guys mean ?

there's an o-ring on the fuel pressure regulator where it connects to the injector. when I replaced mine the old o-ring was stuck in the injector. if it was left in there or not replaced with the new pressure regulator it would leak in the upper intake.

ok cause i had bought a o ring kit that had to o rings in a big one a a smaller one i couldnt find were they went on the injecter so i didnt use them any idea about those ? but yea i dont remember there being a oring on the old one

those are more than likely the fuel line o-rings, one is smaller than the other. since you didn't remove it you didn't need it. If I was you I would remove the Intake Manifold Tuning Valve and look to see if there is any gas standing in the lower intake manifold. After you replaced the FPR did you first check for leaks buy turning the key to the "run" position before replacing the upper manifold?

If you feel something went wrong or you have a bad FPR, I have a brand new one in the original package that you can have if you pay for the shipping and have paypal. just pm me if your interested.

i thought maybe they was the fuel line rings to but the was to small to hold the line in place it had alot of room around it also could i have mixed up the fuel lines going to the spider injecter ?

I don't remeber if it was possible to mix up the puel lines, but I think in would be difficult to get it assemble right if you mixed them up. the lines are the exact length and are formed to fit back in the correct spot. You should have replaced the fuel lines in the upper intake( "nut kit" ), they get very brittle with age and are easy to break. I think the o-rings you have are for where the fuel lines connections on the outside of the upper intake.
