Exact same problem that I had on mine. The typical resistor trick was useless. Here is the only thing that saved it from the junkyard: http://newrockies.ca/vatsbypass

Why wont my 99 Buick regal ls stay running it starts then immediately stalls out


Is your SECURITY light flashing? If so, you have a V.A.T.S. problem. VATS stands for Vehicle Anti Theft System. Try getting a new ignition key made because the resistance value has probably changed in the one you have. If that doesn't do it you'll need to get a VATS bypass.

The catalytic converter maybe clogged. This would result in a car starting then cutting off. you can unbolt the catalytic converter see if that solve the problem. Then if that was the problem replace it with a new one. Goodluck.

Car starts and runs for about 13 to 20 minutes got new computer map mas still no go. wait for engine to cool off and will start. fan does not engage but sensors test ok. during diagnostics fan will run i ...


Just did one in my shop yesterday. MY problem was injectors shorting out drivers in PCM after half hour of cooling down it would restart and die again about 20mins later. You need to narrow down what is dropping out. Most likely your loosing injector pulse and/or spark. You can buy a noid light for injector testing and a inline spark tester which you can tag on igition coil pack from local parts store also you can tag into injector harness on passenger side of engine with noid light, when it stalls see if light is blinking while cranking on both testers. IF you have spark but no injector pulse you have one or more injectors shorting (acceptable range is 13 ohms) any lower than 13 ohms injectors are toast. IF no spark and no pulse your ignition module and or crank sensor are bad, replace both, module is under coil pack and sensor on side of block.

My 95 buick lesabre will not start , I have change to a new fuel pump and a new cam shaft sensor. The gas is getting to the fuel rail, I have spark on all six cylinders . If i spray gas in through the mass...


Thee are a couple of things left to check. One is to hook up a fuel pressure gauge to the fuel rail and see how much pressure your getting and compare it to specs. It maybe getting fuel there but not enough pressure. To see if the injectors are being pulsed you wil need a set of noid lights. You will unplug an injector and plug in the noid light. It will flash everytime that injector is pulsed. If it never flashes your injector drivers on the ecu are bad.

Idealing issues


Needs a tune-up:

Spark plugs and wires and distributor & rotor.

Do wires last... the others probably need to be done.

Hope this helps!

1999 Buick regal Security light on. Won't start.


I had the same problem with my 95 Lesabre. The owners manual says to take the key out, and wait 3 minutes(until the light goes off). It should fire right up.
