Hi, I have a problem with my 1998 Buick Lesabre periodically stalling out while driving. Sometimes I was able to put the car in neutral and restart it while still driving.

However, a few days ago I went to start the car and it started up, idled very rough, backfired, and then stalled. Now it will only crank, start up and idle very roughly (sounds like a growling noise) and then stall after a few seconds.

I was told to change the crank shaft sensor, the fuel filter, and/or fuel pump. I was told to start with the sensor first.

Yesterday I went to a local autoparts store to by the crank shaft sensor but the man behind the counter recommended that I remove the ignition module and
bring it back so that they could test it.

He advised me to check the module first before spending the money for the sensor (and special tool that is needed to get the old one out). He said that they sell more ignition modules than they do crank shaft sensors so he would start with it first.

Can you please advise me if this is true? Or should I try the easier things first like changing the fuel filter?

I would like to get it running so that I can get it to the shop to be completely checked out. Thank you guys for any help you can offer.

Thanks again,
Mark

ps. I will be donating to those that can help me get it out of my driveway and to the shop. From where I live the tow would be very expensive so that is why I would like to be able to drive it there.

Thank you,
Mark

Mark:
Before buying anything, I need you to check for a couple things. First start by checking if the engine is getting spark. If it is, the crank sensor and module are most likely fine. Next, check for fuel pump pressure. Here is a "How To" video for you to view.

Also, the gauge needed can be rented at many parts stores or one can be purchased at the "test Equipment Store" on this site.

Let me know what you find, and we'll go from there.

I went out to check a few things under the hood of the car. Upon opening I saw that the large plastic shroud/cover on top of the engine had a huge crack in it. After I removed the cover, I then found that, what I'm guessing, is the throttle body blown apart right down the middle.

I have taken pictures that I wanted to post, but I can't seem to get the "upload and insert a picture" feature to work on this site. The pictures upload to somewhere, but when I check "my photo album" it says I have zero pictures.

Is it possible to email the photos directly to this site or someone that can possibly help me? Please let me know.

Thanks again,
Mark
