Yes, that was the first thing we tried. I will try it again.

Already replaced CPS. Still not starting just cranking with a backfire now. Any other ideas? Could it be the ECU or Timing chain slipped or something. Please someone give me somewhere to start again.

Stuck with Bonny cranking but not starting! Checked fuel pressure with gauge and it is withing specs. Cleared codes as stated above by replacing O2 Sensor, ICM, #2 & #5 ignition coil and just replaced the Crankshaft Position Sensor. Also did the VATS bypass today and still will not start. Now it ...

Ok, so we changed the ICM and replaced ignition coil for #2 and #5. Still cranks but won't start. Still looking for a fuel pressure gauge. My mechanic friend does not believe it is the fuel pump since we can hear it turn on and when trying to start engine it floods. Going to replace the crankshaft ...

Update: Got obdII data link to work and pulled 2 codes: P0133 and P0305. Replaced O2 Sensor and #5 ignition coil. Still will not start. Don't have a fuel pressure cage. Any ideas?

We just removed one of the spark plugs and looks, and smells like fuel. Car is flooding.

He checked all three banks for spark but I am not sure if he checked the fuel pressure with a gauge. I will have to get to you on that.

I have a 1998 Pontiac Bonneville SE that cranks but won't start. Just got this car last November. Noticed before that coolant level was low a few times (topped it off) and a couple days before it took a dump on me it was nearly empty. Now I noticed that when I turn the key on the security light ...
