I have been having alot of problems with my 1998 Tahoe. I will start by telling you I had my engine rebuilt 2000 miles ago and recently had the distributor moved a tooth to get rid of check engine light (crank/cam code) and replaced a fuel pump 5 years/20,000 miles ago with an ac delco fuel pump. My recent troubles started with a pulsating fuel gauge, then hard starts, then I noticed a faint smell of gas on my oil cap, so I hooked a fuel pressure gauge up to it and it read 50 PSI with the engine on but not started which is low and with the engine started the gauge began to pulsate (moving rapidly) between 40-45 PSI. I also had my battery tested and it tested at 12.47 volts but only 382 CCA and it is supposed to be 700 CCA. Can a bad battery make me have all these symptoms? Bad battery making my fuel gauge pulsate in the car? Bad battery making it hard starts and the hard starts making my oil cap smell like fuel? Bad battery not giving the fuel pump enough voltage throwing off my fuel pressure gauge? Or is it something more like a fuel pressure regulator or leaky injector or even another failing fuel pump?
