I would like a little help from someone who knows more about cars than I do please... I bought a Cobalt from a guy who said it died in traffic. I noticed that the fuel injector fuse was blown, so I put a good headlight fuse in it. I pulled the fuel rail off and it sprays fuel nicely for about 5 seconds while cranking, and then you can see the pressure drop to zero over about ten seconds until it's just a drop of fuel at a time. If I pull the battery power and let it sit an hour, it does the 5 seconds of injecting fuel again. The Cobalt runs fine if I slowly drip fuel Into the intake hole... I replaced the fuel filter, thinking is was plugged.... Can I get some things to try/test? I'm pretty new to working on cars, and I like cobalts, so I would like to get it running again Thanks!
