94 5.9 Magnum out of a Van.
When key is turned to "run" everything pwers up 2 seconds, then all 8 injectors Click once and the power turns off.
By powering on and off i am reffering to the status of ASD relay and fuel pump.
When engine is cranked over, ASD briefly triggers on and turns back off immediately. Subsequent attempts to crank engine will not cause the computer to trigger the relay again UNTIL full power cycle. i.e. once the key has been turned off fully and back on.
cmp sensor tests normal as per haynes manual. 5v on signal wire with rotor facing firewall, 0 volts the other way. voltage hops 0-5 while cranking.
ckp sensor - cannot find a test for this sensor other than to use a scope. i dont have one, and the engine wont start anyways sooooo...yeah. i did try a new CKP sensor from the parts store and it made no difference.
The coil has power, but never seems to get signal to fire from the PCM. Coil bench tests good, and fires a plug when coil - wire is tapped to ground.
My only thought is the PCM is shot, or i dont have something wired up correctly.
I have batt + power going to pins 9,3,57.
Pin 51, asd relay is controlling my fuel pump relay, and idiot light to let me know when the computer is shutting down.
Any thoughts here? Can i take the ecu to the dealer and have them bench test it? I know at Honda we have a breakout box for testing ecu's off the vehicle...i assume dodge has the same sort of device?
