1995 oldsmobile 88 starts then dies right away

:tongue: My 1995 Oldsmobile 88 starts, putters, goes to a smooth idle for about 3 seconds then dies, and not like a shaking die, it just stops turning, also some reason all the dash lights are on even when its running. we replaced the ignition coil, and checked the spark plugs, there all firing, what could be the problem? Thanks for your answers

Welcome to AF, check fuel pressure at the rail first. Post results, should be at least 40 psi.
