Buick Repair Questions? Ask a Mechanic for Answers ASAP
Sounds like the fuel pump might have took a dive.
Can you get a hold of a fuel pressure gauge and connect it to the fuel test port on the fuel rail and tell me what the fuel pressure is when trying to start it please?
p.s. most parts stores will loan you a gauge for free with a deposit.
Let me know please.
We actually need an exact pressure reading because the pump can still pump gas but the injectors require a high pressure to operate and it will fool you if you just notice there is gas coming out of the test port because it probably isnt high enough pressure. It really is necessary to test it with a gauge. I will be around all day so just get back to me if you can get a pressure reading.
Advance auto and Autozone have a free loan-a-tool program and i think Orilleys does also.
If it has 55 psi when cranking it to start thats enough fuel pressure but not much lower.
Your last reply confuses me.
Does the starter engage and turn the engine or is it just clicking when trying to start it??
How did you get the fuel pressure if it doesnt crank?
Do you have a volt meter. If so connect it to the battery and tell me the volts when the key is in the cranking position.
I dont know how a fuel leak could cause the "no crank" condition. I though the starter would engage and spin the engine but it would not start. We will need a volt meter and start with the battery voltage drop test when trying to start it. Hook up the meter to the battery and tell me what the voltage drops to when trying to start it. We have to start there and work our way to the starter first.
Have you had a chance to check that voltage yet? No hurry on my end, just wanted to check in with you.
