So I decided to save a 95 Sierra standard cab short box 4x4 5.7L auto truck from the crusher at our local salvage yard. When I got it, it was in pretty rough shape but the body was good and I was told that it ran when it was brought in. I guess this is all a story for another post so I'll get to the point. It had been picked through and it had a propane conversion on it. I removed the propane conversion and started working on getting it started. Now it didn't have and battery cables, all of the fuses and relays had been pulled out, I have to remove the ignition and replace it but the big thing was that someone had grabbed the ecm. I found one in the salvage yard but it didn't work. I had replaced as many fuses and relays, the ignition. I was still getting no spark no fuel.So I assumed the ecm was bad and I ordered another one off of ebay. While waiting for it to arrive I went through and did some tests and rebuild the tbi and replaced the spark plugs and coil. The new ecm showed up today and I'll been waiting for it with excitement. I was hoping that I would be able to put it in and atleast get some spark or fuel but nothing. I checked the fuel pump relay and it isn't getting power on pin 85 or 86 which would mean the relay is not engaging. When I put the tbi off to rebuild it there was no fuel in the lines. I'm not too sure where to go from here. The first ecm was questionable but the second one was pulled off of a running truck. I'm thinking the next step from here was going to be looking into the crankshaft position sensor(if I can find it). Any help would be greatly appreciated. Thank you
