Question about 1997 Chevrolet Lumina
Have done full diagnostic, replaed battery cables, relay, checked fuses, trace wires for break, tested continuity and grounds. Jumped the relay 87 to 30 and the pump turns on however, the car still doesn't start. Im at a loss. My uncle tells me to switch out the camshaft sensor but i dont see how that will help. Any ideas?

Check your connections. did you run the fuel pump wiring under the drivers side door sash like GM did?.. if so check for nicks in the wire or bending or cracks.. this happens.. happened to me. check your fuel pressure. 40 dollar part at an auto store. If its below 59 PSI it wont work. And blazers are very intolerable to low fuel pressure. Also try taking the negative post off your battery for a little while and then putting it back on and if you can get it started again drive around (if its safe and running decent) for at least 30 minutes to get your car computer system acclimated to a new functioning part. Did you check the fuel filter?. rule of thumb when a pump goes change the filter its always the last thing people expect because we all jump to catastrophic engine failure at the first no start moment. lol.
Make sure that all your ducks are in get my drift.. Air oxygen fuel thats the mixture you need to check all those vital parts. before pulling your head off.

I would check to be on the safe side the fuel filter is going in the right direction. The arrow is pointing towards the engine away from the fuel tank, Then you need to make sure the fuel pump wiring connections are good contact and did not come loose when driving.

Your ECU is what acctivates your fuel pump realy. Put the key on the run possition and pull the ecu fuse for a few seconds and reinstall it ans it should accivate your realy for 5 seconds, Good luck.

I've been bitten by this twice! The culprit both times was the connector plug under the van infront of the fuel tank. the second time the connector pin and socket came loose inside the plug itself,( workes for a while then dosen't). Make sure there is good secure contact made in all sockets in this plug, and the pins are held where they need to be inside the plug itself.
