my 91 ram will randomly die, and not want to start up again for a good 2-3 mins, sometimes even longer. it happens randomly too, some days it does it some days it wont. am i looking at an idle air control valve here? ive already tried replacing the TPS. help?

 

does the truck give you any codes? also when it wont start can you hear the fuel pump cycle on when you turn the key to the run position?

 

my truck wont put out codes and yes i can hear the pump cycle

 

it has to put out some codes even if it is just a code 55

ON-BOARD DIAGNOSTICS Dodge OBD1 Pre 96

1. Cycle the ignition key ON-OFF-ON-OFF-ON within 5 seconds. To cycle the ignition key ON means to turn it only as far as it takes to get the radio to come on. It does not mean to turn the engine on.

2. Count the number of times the "check engine" lamp on the instrument panel flashes on and off. The number of flashes represents the code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses separate individual codes. For example, flash-flash-flash [pause] flash-flash represents the code 32.

A code of "55" represents end of error codes. If this is all you get then no error codes are stored in the computer. This is the normal condition
