Sorry about you luck. but here goes how to check it. Pour a little gas in the air inlet ( take the hose off the thriolle body.) crank it and you got fire up briefly then you know you got spart but no fuel. If it runs the fuel pump and the amount of gas in the tank are to be checked. Fuel pump fuses and relays, amount of gas in the tank. Let's say it didn't do nothing but crank, Maybe it doesn't have spark. Take a plug wire off the easies plug you can get to put an old plug or a screwdirver in the end of the wire lay it on metal and crnk it and watch for spark. ( don't hold it in your hand as if it is working it's shock you bad enough to kill you, In the worst case) You see spark and it still won't flash start with extra fuel added. Then you'll have to take a plug out to see whats going on in there. With the plug out it could be soaked with gas, antifrezze, oil, or anything else under the sun. But it could be dry and normal looking too. Test this plug in the end of the wire laying on the exhaust maniflod. If no spark your back to that or it sparks your back to gas. But let's say you still can't get it to pop off any. Maybe it over heated and the engine has little or no compression. ( with the plug wire and the plug out of the way put your finger over the hole the plug came out of and crank the motor if it blows your finger out hard its good but if you can hold it it's bad) ( blown engine ) Your not done yet ,! Put a little motor oil in the plug hole and crank it again if the pressure picks up lot it might start if you do the same to all the cyclinders and then with it all put back together start it. (It'll smoke like crazy so be ready for that) But it still might nor start. The timing chain could have skipped and the timings off enough that it won't start. Most likly it doesn't have sprk and the dist. cap is behind the water pump and it's hard to check as you need to remove the water pump to get to it. The coil wire can be removed first though and check for spark at it. No spark and the dist is turning the crank senser and or the ingition module could have failed. Take the module off and that it to the auto parts store and they can test it and sell you a new one if its bad. If you find no spark first then get the module tested before you do anything else. If the crank senser is bad you can unplug it and cross the wires the are in the plug with a paper clip on off on off and the coil should fire with a good module and the key on. If it does change the senser and you have spark and it'll run if you put everthing back together right. The cap and rotor are bad about failing on this car and they're expensive. The coil wire will fire even with a bad cap and rotor so don't jump to this till you getr good spark at the coil and not at the spark plug. Coil wire can fail too. The cars old enough that all the parts are in question till their proven good.

Interchangeable car parts


You didn't really specify which parts, but many parts are interchangeable between the 1991-1996 B-body cars (and D-body, the Cadillac Fleetwood). The B-body cars were the Caprice and Roadmaster (Sedan and Wagons), Olds Custom Cruiser (only produced until 1992) and the Impala SS (1994-1996). They all share the same frame (D-body is slightly stretched) and most of the suspension parts are the same, or at least interchangeable. The interiors are different, but most things like seats and door panels would be interchangeable. The B-bodies started out with Chevy 5.0 Liter and 5.7 Liter TBI engines, later the L99 (4.3 Liter) and LT1 (5.7 Liter).

AT TIMES ACTS AS IF IT RUNS OUT OF FUEL,DIES.BUT FIRES RITE UP


hei module on the distributor can cause the same problem, but if it is an lt1 the distributor could be going out. The lt1's are known to get coolant inside of them and burn up. Easy way to check the problem is to get a fuel pressure gauge from advance auto parts and check the fuel pressure while your driving, just zip tie the gauge the the wipper arm and watch the gauge while driving. It's easier with a co-pilot.back to the Hei module, this module sends a signal to the computer to control injector pulse and ignition fire. If you take it off( under rotor) and bring it to Advance they can check it.
