2005 Malibu Classic 4 cylinder won't start
Car had not been problematic until one day the check engine light came on and seconds later it died in traffic. Towed it home and trouble shot. No fuel pressure no pump sounds the car would start when starting fluid was sprayed into intake. Checked fuel pump relay and it had 12 VDC. Swapped the relay with another with the same number. No change. Jumpered the relay. Still no fuel delivery. Replaced the fuel pump with a sued pump from a salvage yard. Car started right up. A week later it died. Repeated the trouble shooting as before. Took the pump back to salvage yard and they replaced it. Installed and the car started right up. 2 weeks later it died. Had car towed to a repair shop. They couldn't get it started when it arrived. The next day it did start and they couldn't find anything wrong with it. No charge and I drove it home. A few weeks later it wouldn't start (at home). Again no fuel pressure, no pump sound and starting fluid would get it to run. Ordered a new pump on line. When it arrived I checked the voltage at the fuel pump and got 7 VDC for less than a second once the ignition was turned on. The voltage quickly drops to zero. Have not installed the new pump yet.
