ZR-1 Net Registry Forums - View Single Post - testing the ALCL. poor cold start running

I put the pressure gauge on my Malibu and it held 30psi.

Also the gauge will hold 23psi with the ignition on and turned off after the car has started.

I replaced the clamps with metal ones, all 6, and ignition on it jumps to 23psi, and the same when starting the car/idle. It holds pressure when I turn off the car.

I am pretty sure its the pumps. They are old and just before all this I rode around on reserve twice waiting to get gas since I was going to Indiana (i'm about 5 miles from the border, maybe less).

Do the suburban pumps drop in without any issues?
