If you have a vacuum gauge, just check the vacuum coming out of the vacuum pump. It should read around 24 to 28 inHg Start there and if the pump is working you can work your way over to the vacuum regulator. Just pull off the rubber hose and hook up your vacuum gauge. Quick and easy, and will get you back on the road. The vacuum coming out of the regulator should read around 12 inHg if I remember correctly. My suspicion as Keith mentioned, is your vacuum regulator is bad. Easy to check in about a minute with a vacuum gauge.Thank you both for all the help. I know the 2 piece vacuum hose connection at the injection pump is cracked. I did a partial jacked up fix on it. I replaced a small section of the hose too. Hopefully I will get some more free time this weekend. Thanks again.
