98 Buick Regal Will Not Start

The engine turns over. It is getting gas and the Ignition module tested ok. Any Ideas? I hate to have it towed to the dealership, but I dont know what else I can do. THANKS!!!!!

How many miles on your Regal? Do you have a SES light on? And might want to get it odb-ii scanned for DTC error codes before spending big bucks at the dealer. :2cents:

Car has 86,000 miles. The SES lite comes on when I turn on car. (I thought it always did that, but unsure). Do you have any suggestions on a cheap scanner that will work??

The SES comes on initially for lamp test and then should extinguish when the engine is running but evidently you're not at that point because it won't turnover.

A relatively inexpensive scanner available at Autozone, Checker, etc. is the Actron PocketScan CP9125. Cost $69 - $79. It reads generic odb-ii codes and comes with a reference book. Plugs in at the the port located on the driver's side below the steering wheel and by the center console. Another inexpensive one is the Equus 3100 scanner which reads obd-ii generic (P0XXX) and manufacturer specific (P1XXX) codes. Costs ranging from $99 - $129. Both are easy to use, hopefully picks up the DTC error code and gets you to the right sensor like possibly a crank position (CPS), etc. Good luck!

I can get the codes with a paper clip on my 1991 Buick Regal. Do youi know if I do it on my 1998 Buick?

Also, Do you have any idea what a dealer will charge to replace the crank position (CPS),

One more thing..I did not think it could be related, but I had the oil changed locally, then drove it home (4 blocks). Later that evening I got it to go uptown, and thats when the problem started. Is this a coincidence??

On your 1991 Regal it was odb-i compliant so you could jump pins a to b on the data port, however, odb-ii requires a scanner/code reader. No other way that I know of.

You can get a CPS at Autozone for around $50 but I don't know what a dealer would charge for parts. As to labor its about 2 hour job. I had one changed at an independent shop for $80.00 and supplied the CPS myself.

They have to put the car on a lift or use a pit, take off the serpentine drive belt, remove right wheel, plastic covering on the passenger side wheelwell, and remove the pulley/harmonic balancer to get at the CPS, etc.

After a CPS is changed a CPS re-learn procedure must be run to reset the timing for the ignition system and ECU computer.

Dealer said it was the fuel pump, and the fuel regulator had a leak. Total cost of $785. (Too High i think). I thought it was getting fuel bec I pushed the valve on the regulator and gas shot out. Do you agree with this?

Thats probably right, although high, on cost for labor and parts since its a dealer. They must have tested the fuel pressure at the fuel injector rails, etc. It should be somewheres around 40 - 50 psi. As to the leaking fuel pressure regulator if its a visible leak I'd probably agree and if you remove the vacuum line from it to the throttle body there should be no fuel in that specific vacuum line.
