New to the board seeing if you guys can help me out. I just purchased a 1999 ram 1500 with a 5 speed 5.2. Last owner claims truck died while he was driving it and would not start again. When I turn the ignition to the on I do not get a check engine, truck will crank and crank, truck has no spark also in the engine bay I noticed that someone had hardwired the fuel pump witch run continuously now when the ignition is on . Since the check engine is not coming on my first instinct was to get another PCM. I bought one out of a so called running vehicle out of a yard with the same number, plugged it in and no go. Any one have any ideas? Would a bad crank positioning sensor make the check engine light not come on, or make the ecu not power up? Also looks like someone has replaced the ASD relay

Probably to late to respond, but my son had the same problem and replaced the crank position sensor. We pinched the wires when we swapped motors.
