My 1991 Buick Regal started up today and I let it warm up for about 10 minutes then it died on me and would not start back up. But when it do start it dies on me just going around one block it might start right back up and go but keeps dying every 5 minutes what could be the problem

how do I change a fuel pump on a Buick electra park avenue?

Check your fuel injectors

After changing the ignition module, you may have broken the communication between all the components in the anti theft security system. This is common on GM antitheft systems. Check out this link for how it works and solutions to security problems. http://vatspasslockpasskeysecurityhelp.yolasite.com/

check for power to the key check for power to the coils,and check the starter it may not be turn the motor over.goodluck hope i helped.

check the hose for the pvc vavle it could be split

egr valve is not opening up when the engine reaches it normal operating temperture

one of 2 items are probable. have the ignition module tested. also check the crank position sensor.check for spark and injector pulse when it dies.

Check the harmonic balancer

I have a 99 Buick Regal and it too dies out, but only when I use my turn signals. Sometimes, when trying to start the car...the dash lights would flicker and you can hear some sort of electrical ticking sound. As of today, my car will not start (5/24/09) it hadn't turned over since yesterday. After a process of elimination and searching the net, I think I need a new ignition switch. You may need one as well.

Replace the timming chain, gears, and magnet. With that cat getting that hot it has to be out of time. When the cam sensor picks up no signal, ecu can't control timming and reverts back to a preset,fixed base # .
