possibly the fuel pump. here's a hint for code reading on a intrepid older than a 96. put the key in the ignition and turn in on without starting the engine. in this order
ON OFF ON OFF ON
then leave it in the on position. the check engine light will start flashing a mourse code at you. count them. all codes should be read as double digits. so if it blinks three times then pauses and blinks another four the code is 34. and the code reading will end at 55. write down the numbers and look them up.
The fact that you get enhanced ignition by physically enriching the fuel air mix indicates that the normal mix is too lean, either too little fuel or too much air. 1) Check for leaks of un-metered air in to the air ducting and inlet manifold. Look for cracks and poor joints to all vacuum lines including the evaporative emission recovery lines. 2) Check that the EGR valve is closed off at start up: this should stay closed until engine has warmed up. 3) Finally check that the coolant temperature sensor is working OK; the sensor should be informing the ECU that the engine is cold and the ECU responds by ensuring an enriched fuel mix (by prolonging the injection cycle) during engine warm up.
check gas flow there is a little valve stem on the gas rail. if no gas then the fuel pump is gone see if you can hear it turn on when you turn key to the red lights in dash no sound try leaving key on and kick the tank fuel pump could be stuck.
