IF no fuel pressure and no spark first thing in the day when cold and the relays start clicking,
THEN replace the (PCM/ECM) Powertrain Computer Module AKA Engine Computer Module
THEN the crankshaft sensor if needed.
let me know how it turns out,

check the ignition switch and check the electronic fuel pump

WHAT DID YOU FIND OUT ABOUT THIS PROBLEM? I AM HAVING THE SAME ISSUE WITH A 94 Dodge RAM VAN. Please let me know. I get an error code 54 and 45 on the computer. 45 Is "open or short in transmission overdrive solenoid" which can be caused by the precursor engine error 54.
In most Dodges, especially my 94' Dodge Ram Van 3.9ltr, the code 54 is fuel sync related. Primarily related to a fuel, cam or crank sensor. My problem is still unresolved or confirmed by a solution so I can not provide a resolution but follow me on mySpace/TimFrentz or Facebook and I will share my final resolution with you when available.
My problem: When I turn my ignition on I have to wait several seconds for the fuel relay to click and then stop clicking. This signifies a shortage of power in the fuel pressure wiring systems. On a warm day this seams to only take seconds but on a day below 40 degrees it seems to take as long as 30 minutes and it doesn't seem to start clicking until I tap the relay or try to turn over the vehicle several times to build current or fuel pressure. What makes this issue even harder to diagnose is that the problem is also keeping the distributor from sparking. So far I have replaced the Crank Sensor, Distrbutor Cap/Rotar/Wires/Plugs, battery w/ 900crank amps, cleaned the negative contacts, checked fuses, fuel filter and pump, and changed oil/filter. I'm now researching the possibility of it being caused by an ignition system component.
*After each thing you try, disconnect the battery for 5 minutes so the computer reset's.
