2000 regal will not stay running

what would cause my regal to keep stalling out? it will start but only run for long 1 or 2 secounds. last night i got it to run so i went someplace but this morning it would not stay running. someone told me it might be the security system. what is this? i never heard of this.

Are you getting the flashing SECURITY light on the Instrument Panel? The anti-theft system is called Passkey. You should have PassKey II.

Try using the spare key if you have one or cleaning the resistor pellet. If wrong key is used the system will sense it and then disable the starter and fuel system. Sometimes the decoder malfunctions and doesn't give off any warning like the light. The car may start and run a few seconds but then shuts off fuel and you'll stall out.

not getting any light but i got it to start but i had to keep the accleator pressed to keep it running. if i let up it would stall out and also i am getting a lot of smoke out of the exhast.

What color....dark or black?

I had a similar problem with my '99 Regal LS back around 80K mikes, it now has 114K.

Hard to idle unless I kept my foot on the gas and it would act like it was having a bad misfire. Black smoke out the exhaust and backfiring. It turned out to be the MAF sensor located on the top of the throttle body.

You can try removing it and cleaning the hot wire elements with electrical/MAF contact cleaner. Held on by 2 torx safety screws.

With the engine off, disconnect the electrical connector on the MAF. Start it up and see what it does. The initial idle until it warms up may be erratic at first. The sensor normally throws a DTC error code and a SES light but not always.

where is the MAF sensor and the throttle body and what does it do?

where is the MAF sensor and the throttle body and what does it do?

The throttle body is the device that controls air intake into the upper intake manifold via the accelerator. Located on the driver's side of the engine where the rubber ducting comes in from the air cleaner assembly. Remove the plastic engine cover. On the top of the throttle body is a small square black module with an electrical connector. That is the MAF sensor. The MAF senses air flow and sends that data to the powertrain control module (PCM) to help control air/fuel mixture to the fuel injection system.

Here is a pic of the MAF sensor:

i am going to check that, i will get back with you- thank you for your time

ok i found it now what do you want me to do? should i buy a new one or clean this one?

Cleaning may help but in most cases probably not. But it doesn't hurt.

For now with engine off, simply disconnect it. Start engine and see what it does. The idle will be erratic until the engine warms up some but it should idle OK if the MAF sensor is your problem. I ran with a bad MAF sensor and disconnected for one week until I got the replacement. Fuel economy may suffer but it should run because the PCM will detect no MAF sensor signal and go to pre-programmed default settings based on rpms and throttle position.

where is the fuel pump resister on the 2000 regal?

Do you have a Regal GS or LS?

my 2000 regal is a LS 3800 engine

my 2000 regal is a LS 3800 engine


The answer is you do not have one. Only the L67 GS has a fuel pump resistor because it has a fuel pump hi-speed relay making the fuel pump have two speeds. It needs the extra fuel pressure due to the supercharger.

On the LS all you have is the fuel pump relay located in the engine compartment fusebox. It controls the fuel pump directly without any resistor.

If you suspect a fuel problem (fuel pump) you can test fuel pressure at the Schrader valve located on the fuel pressure regulator (FPR). The FPR is located on the driver's side of the front fuel injector rail. Pressure should read 48 - 55 psi.

can you show me a picture of the fuel pressure regulator? funning thing about this is i can start the car and drive it around the block for 10 minutes and then when i pull into my drive way which is about a 45 degree incline my car will start to stall out and i can't keep it running unless i press on the pedal. also the mile range on my dash which shows how many miles i can get with this tank of gas is low but i know i have more gas in there. my gas gauge show i have a lot of gas but the mile- range shows low gas. got me hitting my head againts the wall.

The item circled in red is the fuel pressure regulator. The Schrader valve is located on it. Fuel pressure gauge hooks up there.

The regulator can be tested. When you run the baseline fuel test and connect the vacuum line fuel pressure will drop to around 45 - 46 psi. There can be no nore than a 7 psi difference. If there is the FPR is bad.

You can remove the vaccum line and see if there is any fuel in the line. If so then the diaphragm is ruptured. A bad FPR may give a similar problem.

A single c-clip holds it onto the fuel rail and bracket. It just pops off.

thank you, i will try your suggestion

I have been told there was a recall for buick regals because of leaking antifreez into the engine from the intake manifold. do you know anything about this?

I don't believe there is an official recall on your year model. There are GM Technical Service Bulletins (TSBs) out on upper intake manifold/lower intake manifold problems. The older 97 - 98 Regals with normally aspirated Series II 3800 had problems with the EGR stovepipe damaging the plastic upper UIM causing high consumption of coolant and driveability issues. GM supposedly resolved the issue on 1999 and up models by going to a smaller EGR stovepipe, improved UIM and gaskets. However, I do know of 1999 and up model owners that have had problems with the UIM and LIM gaskets but it is not a common problem.

thank you

GM will replace the engine throttle body fasteners with redesigned fasteners and add cooling system sealent to the radiator tank at no charge thru July 31,2005.If you have already paid to have this corrected before 8-8-03 then they will reinburse you for parts,labor,fees,and taxes.

Recall notice for 2000 LS Regal.Its for all 2000-2003 3800 Series II engines .It says some engines have developed coolant leaks at the upper intake manifold to throttle body gasket or at the lower intake to upper intake gasket.


I found this on the enternet-- could this be what you was talking about? could this cause my problem of stalling out?

The notice was based on GM TSB #03-06-01-016 released in 2003. It is one of the TSBs I mentioned earlier.

Requires replacement of upper intake gasket, throttle body gasket, or lower intake manifold gasket, Kit Part # 17113137 if there is a loss of coolant or milky colored engine oil or external coolant leaks. Affects VIN "K" 3800 V6 only.

Do you have any unexplained coolant loss or cross contamination of coolant in the engine oil? Coolant leaks noticeable on the engine or on the ground?

when i disconnected the wiring of the mass air flow i broke the positive wire from the plug. is there a way to reconnect this without buying a whole new plug?
