Hello williamcole7: My name is Roger and I will help you. The code 888 is a test code. This tests the L e d's of the dash cluster. All segments must light so you can read all numbers. The 70 code means the system is ready and able to function. The ff code is a current BCM code and is happening at the moment. The f 40 code is a BCM history code and means it was a stored problem or something that has happened. The f 40 code is for a air mix door problem. THe BCM would set this if you had an A/C problem. The E 48 code deals with the EGR system fault. I would check for a vacuum leak at the EGR solenoid. The hose is prone to deterioration do to heat from the engine. Code E52 deal with loss of voltage. A dead battery or a disconnected battery cable will always set this code. None of these codes will keep the car from running.The repair schematics are to extensive to send in a reply. Should you need further help ao assistance I will be glad to help. Please rate the answer. Thank You for using Fix Ya. Roger

Sounds like you have a either a vacuum leak or a cracked fuel line allowing extra air to be sucked into the carb fuel mixture. Make sure all small to medium sized hoses are well attached to their fittings and do not have any cracks in them.

Jumper 12 volts to the blower motor and see if it runs, it may be a defective motor.

Next time you have the problem check the fuel pressure, bet you have none. The fuel pump is electric and located in the fuel tank. These fuel pumps last on average about 100,000 miles, less if you run the tank lower than 1/8 due to the overheating it causes the fuel pump due to the loss of lubrication and cooling from the fuel it sits in.
