99 frontier question???

[dennismiles]

I recently bought this truck. The previous owner really trashed the inside with grease all over the seats and carpet. I totally cleaned them up saturday, then started the engine and turned on the heater to dry them out. The truck ran for 20 minutes and then just died. Yes it has gas, and is getting gas when I try to start it, just no fire to plugs. I took a plug and wire lose and had wife turn over engine, and can see that I am not getting any fire. I checked fuses thinking that maybe I got them wet, they all appear to be fine. help!!!
