The car will start, idol real good but when you put it in drive it starts to pudder and will turn off in a matter of minutes. Do you happen to have a solution???

I have a 84 Buick T-Type it's getting fire an it gets gas up to fuel rail but I don't think the injectors are spraying


Have you checked the injector circuits with a test light to see if you have voltage and a pulse ground from the computer ?
Can you spray carb cleaner into the intake to make it try to start ?

Location of thermostatic switch 1993 Buick Regal 3.8 motor fan motors don't run


The fans are controlled by the ECM and it uses the ECT sensor for temperature sensing, so if the check engine light isn't on the sensor is not the problem. You need to have an active test run on the fan system to see what code is returned. Have you tried powering up the fans at the relay?

I'm trying to put in an aftermarket radio in my 1993 Buick Regal Custom. The wires for the new system are clearly labeled, but none of the old one's are, and even with a list of what color cable is what, I...


I usually buy a wiring harness adapter off of ebay.com or BestBuy.com to get wires that are labeled to work with the aftermarket radios available for your Buick Regal.

They don't cost much and can save a lot of headaches.

1993 Buick Regal Custom 3.1L starts, runs about 5 minutes and then stalls. I think it is the MAF sensor, but I can't find the MAF sensor, and my Chilton doesn't list it for this model/year/engine...


it is the large round piece located in the round plastic flex tube that connects to your air filter and the other end to the throttle body,you can do a tap test on this piece,start your car,and tap on the flat part of the MAF sensor,if your car stalls right out it bad,use a screw driver handle to tap with.

Don't know what type of sensor I need for my 93 Regal


If your check engine light is on the computer in your car can give a code. Aamco will read your check engine light for free. Might need a repair manual to find out what code means (which o2 sensor). If check engine light is not on you will probably need to get each o2 sensor tested by a mechanic.

Car starts then stalls out...


could be to many thing to take chances with, but most commonly;fuel filter,gas line antifreeze or a crack in your air intake which would take your vacuum seal away, start with the least expensive and work from their. Worst case scenario pinched fuel line

Test your fuel pressure, make sure it is the right pressure and test the fuel volume.make sure its getting the right amount of fuel. if it checks out ok you need to put the car on a diagnostic machine. you may have a signal problem that requires a lab scope.

93 Buick Regal not running good. Scanned it, the code it gave me was 26 quad driver module. I am not sure what i can do, does anyone have a solution?


The quad driver is in the computer it drives the fuel injecters. you could have an injector problem if one injector shorts it will cause the code to show up you can ohm the injectors and find the problem e-mail me and let me know what you find Phil
