I have been a Technician since 1986, and a Journeyman Tech since 1994. Sorry I have been offline for most of the last year, but I'm up and running again now. I work at a Chevrolet/Cadillac dealership. I have been strictly GM since 1996, so I will be happy to answer any GM vehicle questions and provide what information and guidance I can. My Email is: ChevyASE@aol.com or I can be reached by text @ 510-334-6152 (please text, I don't answer calls from numbers I don't recognize) My available hours are: M-F 1930-2400 and Saturday and Sunday from 1000-2400 (all Pacific).

Question Answered: 

Need lots more info to help you. Does this only happen when the car is at normal operating temp? When you say "stopped", do you mean shut off and re-started or after the first time you come to a stop? Does it do it cold? Is it only after you have been on the freeway and then get back to in town driving? When it drags, do the engine RPM's increase and the car just not go, or does the engine feel like it has a lack of power and the RPM don't climb at all? Any warnings or indicators come on? Have you had it scanned for codes? Please help us help you.

When you say it won't start, does it crank over normally and just not fire up or does it not crank at all? 2 different problems.

Question Answered: 

Check all your fuses in the dash and underhood fuse boxes. Also check all your ground wires (especially the ones from the engine to the frame and body/chassis to frame) for good tight connections.

I posted the bulletin and repair procedures under the reply from pushrod. If you want a copy of the instructions with pictures, please email me at ChevyASE@aol.com and I will send it to you.

Question Answered: 

Is the engine making any ticking or tapping noises? If not, then it is your sensor or guage. Screw in a manual guage in place of the oil pressure switch and get a reading. If there si no noise, chances are it'll read normal. To test the guage you need a variable resistor box (guage tester). Easier to just replace the sending unit and see what happens first.

Question Answered: 

Agree with pushrod. Not CRANKING and not STARTING are 2 very different things given what you said about replacing the column.

Question Answered: 

Yes. It can cause issues with the AFM system. AFM will be disabled if the system sees (or thinks it sees) low oil psi. Check the wires to the switch and make sure they are not broken or shorted anywhere. If they are not, then replace the Oil PSI switch. If there are still issues after this, then you will need a scan tool (not a code scanner) for diag.
