2001 Bonneville Will Crank - No Start
I was hoping that someone might be able to point me in the right direction.
I have a 2001 Bonneville with the standard 3.8L normally aspirated motor.
I gassed up the night before (not sure if it is relevant) and the car was sitting outside when it dipped to around 0F. The next morning I went out and the care wouldn't start.
My first thought is that there was water in the gas. I was able to push the car into a garage and fire up a heater for a good 1.5 hours. I also added dry gas to the tank. This did not help.
I pulled out plugs 1,3, & 5 and confirmed there was spark. As an additional step, I checked the coil packs as listed here. The values I got were right where they were expected (5.4-5.6 for the secondary and 0.7-0.8 for the primaries). I also checked the plug wires, and found that they should be ok.
I rented a code reader, but there were not current codes in the computer. There was a stored code for a lower than expected coolant temp, but I changed the thermostat and that took care of that code a few months ago.
I also preformed a compression test. The pressures were within 150-170psi, with #1 being the lowest at 120/130psi.
While the plugs were out, I did notice that they were wet. I wiped them off and put them back in. I did spray starting fluid both in the air intake and in the #1 & #5 spark plug holes, but that didn't seem to help either.
The oil is still a used oil color and doesn't look like it was contaminated with water.
Prior to this issue, the car has been starting & running normally. When the temperatures dipped to single digits, it did start a little harder than what it normally does, but I attributed this to the cold temperatures we received the past week.
Is there any other suggestions that you would suggest checking? I'm half tempted to take it into a local shop and see if they can diagnose the problem.
Thanks for your help.
