    Battery seems to be fine. Car seems starved for fuel then floods but will eventually start.

    Everytime we pump the gas pedal it starts after awhile. It may need a tune-up as it idles slightly rough and backfires when trying to start it. Battery checks out at 13v

SOURCE: Car wont start, no clicks no sound

make sure you have power getting to your starter when you crank. check the small nut on the starter. should have 12 v or very close to it. this will tell you if your getting power to the starter or if somethign before the starter and something maybe with your anti theft system or not. its hard to say online cause of that anti theft. doest the light flash at all? the anti theft light?

if your getting power to the starter when you crank make sure your getting good power to the starter by turning on the head lights and see if they dim. a good starter will cause the headlites to dim when attempting to start. if nothing dims check connections. or assume bad starter motor. make sure your also getting power to the main starter stud as well.

good luck

SOURCE: '90 Buick Century dies often, will start again after sits 2 hrs

The fuel pump is starting to go. The fuel pump sending unit which is part of the fuel pump is over heating in time and shutting down. This is causing the fuel pump to shut down.
I would replace the fuel pump and filter.

Good luck

Need to check the fuel injectors on my 1990 buick lesabre v6 3.8l

You will need a fuel injector testor, about a $100, and a fuel pressure guage, about a $100, to flow test the injectors.

You can ohm check them with an ohm meter to see if one or more has shorted windings. Remove the electrical connector and test between the two pins. They should all be about the same ohms. If one is significantly lower than it is probably bad. Its best to check them when they are hot (after the engine has warmed up).

Where is the starter located on 1994 Buick Lesabre

You should probably have it fixed. I have a 98' LeSabre and am
wondering why the engine keeps blowing up. I have changed it
3 times now. Keep checking fluids and everything but still not having
any luck. So i hope the help i gave helps you.

I have a 1990 buick lesabre custom 4 door

Hi there,

I had the same problem with my 89 Buick Le sabre. It turned out that I had to replace the computer. It was giving the wrong signals and cutting off the fuel. My engine light came on each time it happened. Since the computer was changed it has run like a charm. It cost about $500.
Also when they ran the tests for the eng light data the computer was giving the wrong info and so many of the wrong parts were first replaced.
