I'm trying to find the location of the coil ballast resistor on a 1988 dodge aries 2.2l with TBI with 147000 miles. It is not in the engine compartment! I'm trying to solve a stalling problem and have replaced all the usual suspects. Original coil was mopar #4176009 which requires an external resistor. Also, is there a cheap way of checking the fuel presure without fancy equipment?
