The first thing I would look at is the distributor magnet. Just pull the distributor cap and glance at it. If it appears cracked, which many are, then you found your problem. It will set you back about $50-$60 from your local GM dealer.
I have a 89 Chevy caprice. When I had my fuel pump changed, they had to drop the tank...it was in the tank.
Dash components can be changed to digital gauges. An online search should show several companies that show a digital conversion for a 93 Caprice.
try the moduel
The fuel pump on an 89 Chevy Caprice is changed by lowering the fuel tank, disconnecting the pump wiring, and removing the fuel lines. The pump can then be lifted from the tank and replaced.
you either did not gap the plugs to spec or you put this wires on wrong
There are a couple of reasons a 1991 Chevrolet Caprice may stall out. The car may need a new distributor cap or the plugs may need changed. A mechanic will be able to determine the causes of the stalling car.
A stock Caprice has a 5.0 engine( the 305), the Police (actually called the 9C1 Caprice) Caprice has an Lt1 350, a very powerful motor that is easily modified. the 9C1 Caprice also has upgraded heavy duty sway bars, suspension, and axles with its 5 x 5 truck bolt pattern as opposed to stock 5 x 4.75 pattern. But there was also a Caprice Classic LT version which also had a LT1 V8 5.7L in 1996. And After the 1996 GM (General Motor Company) Changed that Caprice Into the Impala SS. But that Impala SS had sportier Leather Seats than LT version and Rear disk brakes, better than the drum brakes the LT's have.
This depends on the year and generation of Caprice as well as specific accessory options. Around 1971 the Chevy Caprice weighed about 4,000 pounds, while in 1976 it weighed about 4,300 pounds. Various years had similar weight, however in the early 80s an effort was made to reduce weight. I own a 1985 Caprice Classic and it weighs over 4,500 pounds -- it has a V8 engine and several options that add weight to it. In 1991 the style and engineering of the Caprice changed a great deal. The cars were lighter -- overall about 4,000 pounds. The Chevy Caprice Wagons generally weighed more than sedans and coupes.
