My 97 lasabre periodically stops running at any speed or even stopped. It will not start back up until a few minutes later. It will turn over but not fire off. sometimes it take 10 minutes and sometimes it takes an hour or so before it will start again. What is causing this?

The most common cause of this problem is that the drivers seat heater grid is open or burned out. That is based on 25 years as a Ford dealer technician.

When you have a check engine light, there are codes stored. That's where you start--with the codes

air lock in the cooling system get a plastic bottle cut the bottom off turn upside down put on radiator filler and run engine cut full off water wait until all air bubbles stop then remove and put cap on see how that goes

Fuel pump. The valve in the pump that stops the fuel from draining back into the tank is not working so you crank and crank until the fuel gets up front. Turn the key on but not to start for 5 seconds then off do it five times and then try to start it should start right up

Sounds like the fuel pump is going out. Replace the filter first, as it's only $10. If that doesn't fix it, then it's probably the pump, which is $250.

With the light flashing ,codes are stored in the transmission control module . Have the codes check an this will tell you whats wrong . Probably a sensor or shift solenoid or line pressure solenoid .

What about the fuel pump relay. I had a car that would stall and would take 5 minutes to restart and it wound up being the fuel pump relay.

I had the same problem with mine. I installed a fuel pressure gauge, and drove around until the problem started. The truck should be running between 48 to 56 lbs. of fuel pressure. Mine ran at idle at 42lbs. , not even high enough. Drove it for about 20 minutes, and it started to stumble. Fuel pressure dropped to 30lbs, 20 lbs - then all the way down to 2lbs. I shut it off, and it would not start back up. 30 seconds later, I turned the key and it came up to 10lbs. press. 10 more seconds 20lbs. After almost a minute, it came up to 42 lbs. started and I drove away. I replaced the fuel pump assemb. on 7/3/2008. Drove it around,and the problem is gone. Mine is a flex fuel, and the pump retails for $668.00. I did find a AC Delco pump for $221.00. I hope this helps.

When it stops, does it have spark? (crank sensor)

let me know if you dont get a good answer
later paul
