Cavalier - measuring fuel pressure
('99 Cavalier 2.2, port-injected.)
This particular car doesn't appear to have a tap on the fuel rail where a pressure gauge could be attached. The Chevy book calls for a J29658, which lets you insert a tapped line at the quick-disconnect. This may be a whole 'pressure kit', or something - Kent-Moore said that their price for it is $336. All that I need is something that can go in-line where the quick-disconnect connects to the rail. So far, I haven't found anything to do that. Any ideas would be appreciated. Alternatively, I measured the following ... - pump pressure with the line plugged : ~65 psi - pump flow with the fuel line open : ~45 gph - discharge from the pressure regulator: ~15 gph (engine off, pump running.) This last leads me to believe that the pump and regulator are probably OK: if there's any discharge from the regulator, the pump must be achieving the regulator pressure. Any opinions appreciated. (Car woke up dead one morning - cranks, but won't start.) Thanks, George |

But, looking at the drive with a scope, it looks like the pulses stop - they're there, and then they're not. Is this possible?
