97 bravada wont start turns over just no start
hi i was in the process of paying on bravada for a winter truck well i just about paid it off and the owner called me and told me she couldnt get it started i was thinking it was out of gas so i got some gas in a gas can i poured it in and turned the key over for 3 seconds and turned it back off i was thinking it might be the fuel pump so i had my girlfriend get in and turn the key so i could hear the pump click on the pump clicked on just no start. then i pulled out one of the plugs to see if i could get spark i got spark its barley sparking its orange i am going to rent a fuel pressure tester tomorrow when i get out of work. but could someone help me out.

Orange spark is a weak spark. Should be a hot, blue, spark at each plug. Is the battery fully charged? These things are real fussy when it comes to distributor cap & rotor, use AC Delco only!
Proper fuel pressure, and the ability to hold it after the engine shuts off, is critical. Key ON, engine OFF, fuel pump running, (when the ignition is initially turned to the ON position the pump will come on for ~2 seconds and shut off ). Pressure must be 60psi to 66psi and must remain above 55psi for at least 10 minutes after the pump shuts off.
Post your results.

thanks! i never messed with a fuel pump before so i hope it just needs a complete tune up and i can pay it off she gave it to me thinking it needed a fuel pump she did not want to pay for the fuel pump so i got the truck for 400 bucks

Check fuel pressure and leakdown first. If it comes to needing a tune up, use AC Delco plugs #41-993 and gap them at .060" and use the AC Delco cap & rotor. Use a good quality set of plug wires: Autolite, Belden, AC Delco, etc, NOT a store brand, Duralast, etc.
