I have a 1991 jeep sahara that just broke down. I was going down the road and the rpms went down. I replaced the fuel pump, fuel filter, checked the fuel injectors, checked all the fuses, its getting fuel and spark but still when i turn the key it idles up and shuts off...im stumped and any suggestions would be appreciated. thank you so much.
