93' S10 Blazer fuel pump relay locaton?
1st off thanx for reading! I've heard it's under the hood on the side wall. I was also told it's located in the cab mounted to a bracket on the "cowl". What and where is this "cowl"? I have a 4.3L Vortec MPI engine. My Chiltons book tells just what i stated but doesn't give any information where exactly this "cowl" is located. I think i have a fuel problem and i'm going through process of illimination. 1st i changed the fuel filter and that wasn't it. Next i'm trying to change the fuel pump relay, if that's not it then i go to the fuel pump itself, ughh... Thank God for this Blazer Forum & YouTube. Long live DIY. Thanx again!!!

First off, you dont have a MPFI engine, you have a CPI... In this photo you cant see it, but imagine the photo is wider, it is on the drivers side of that brake booster (the round thing with the master cylinder mounted on it) the relays there will be 2 or 3 of them (if you have AC you have 3) One is the fuel pump, one is the horn, one is the AC... They look like little black boxes about 1.5in cubed... Wires coming out the bottom. The fuel pump relay is the one with the PINK (I think) wire hanging off it thats not connected to anything.
The "cowl" is that cover that your wipers stick out of at the bottom of the windshield.

Great Info! I was just about to start a thread asking about the Starter relay. My daughter's 93 Jimmy has A/C and it only has 2 relays. Anyway, the fuel pump took a poop on me last night. So I am also doing the fault isolation by process of elimination. So far, the ECM B fuse is good, I swapped the 2 relays, no change, I'm pretty sure it is the fuel pump.

PS- I also have a daughter named Madi.

You can get a "loaner" gauge from autozone. its free. But you have to leave the retail deposit incase you dont return it.
