Having problems with your 1991 Cadillac Eldorado ?
Engine miss,replaced fuel filter,plugs,wiring,cap,rotor,distributor,computer under dash,also coil yhat mounts distributor cap,spark plugs, don't know what else to do!!
Do a compression test and make sure it is not a mechanical problem.Could be burnt valve,bad cam,or broken valve spring.If you know which cylinder is missing pull the valve cover and check the valves and see if they are all moving up and down evenly when you turn the motor over.Just disable the vehicle from starting or you can do it with it running.Hope this helps.Good luck.
Bad fuel pump.
