Re: 97 blazer...cranks but won't start
new info. after getting a GOOD fuel pressure gauge this is what the facts are. turning on ignition shows a 55 lb fuel pressure that falls immediately once fuel pump cycles off. cranking shows a 62 lb fuel pressure that holds for 7 seconds and then falls to zero rather quickly. both of these were tried 5 times with the exact same results. however i will add that priming the downdraft with gas did not result in ignition. it did hit on 1-2 cylinders. is this possibly the so called spider under the intake.
