2001 Bonneville no start
2001 Bonneville 150,000 mi
Started it Friday and let it warm up. Got in and backed out of the driveway and it seemed to have a miss. Started driving down the street and the check engine light started flashing. Not the check engine light that shows a code is stored but the one to the left that comes on when you start the car. Drove it back home and left it overnight. Went to start it and check for codes, but it would turn over but not start and no codes stored. I think the fuel pump ran. Any ideas?

How'* your coolant level? Both the reservoir and radiator?

Check engine light is an indication of a severe misfire. Meaning, it wanted you to shut the engine off.
What do you know of the maintenance history?

How long since the last tune up and do you know when the last time the upper/lower-manifold gaskets have been changed?
A sudden misfire condition such as what you have described is an indication that the engine is possibly drinking some coolant. Which always leads to a misfire/engine stumble, hard starting/no starting and worse, hydrolock.

OK, we can at least rule out plugs and wires.
Do you hear the fuel pump prime when you turn on the power to ON?
If so, can you test the fuel pressure at the rail?
