I have recently worked on a 1995 Buick Le Sabre that wouldn't start.
First checked the fuel pump fuse and relay, they were both good.
Then proceeded to change the faulty fuel pump. Proceeded to crank the car up and NO START....
Ended up finding that these buicks have problems with there wiring. So i found the power and ground wire to the fuel pump. Grounded it to the frame, and ran a hot wire up to the dash to a on/off switch that i then ran through the firewall and into a 20 amp fuse link. From there to a power source. Now to start the car, you have to turn the fuel pump on and off when you shut the car off.
But that beats chasing the entire wiring harness down to find a mysterious short.
check the fuel line return if is clear maybe is blocked and do not retur gas to your tank and check the power to pumpand make sure you have good ground . bad ground pump going down fast and some times cheep parts is = lost money
The fuel filter could be gummed up, is it freezing out? I have seen them ice when it is cold from the water condensating in the tank, it freezes when it hits the filter. I would check the fuel pump too, if you turn the key on, listen for the pump to run, If you don't hear it, might be the problem. You could try squirting some fuel into one of the cylinders and see if it fires, Then you will know it is fuel related, and not spark. Hope this helps.
'98 le sabre v6 3800. Dead key intermittent, ie no start, no noises.
new ign switch
park inhibitor possible, but checked where is the starter relay if there is one? what else do you suggest? Is there an immobiliser?
The best way to check if it is the fuel pump is to buy some starting spray at AutoZone, etc... and take off your air cleaner line. Spray the starting spray A LIBERAL AMOUNT into the Throttle Body and try to start the car. If it starts and runs for a second then dies, it is most definately your fuel pump. This is an easy check to do yourself and will sameyou diagnostic time and $$$. Try it and post back what you find!
