"there was a relay missing a ASD relay I put one in it now it has 11.4 volts to the coil, injectors and alt. Only when cranking"
"but nether of them are working when key is on or cranking"
The way I'm reading this, you're saying two different things. If those relays are not turning on during cranking, the first suspect is the crankshaft position sensor or the camshaft position sensor. One thing that might help is checking for diagnostic fault codes which can point to the circuit with the problem. Chrysler makes that very easy. Do you know how to read them by cycling the ignition switch three times within five seconds? The codes should read out in the odometer display. There should be at least one related to the missing ASD relay. Hopefully there will be more.
It's the pulses from those two sensors that tell the computer to turn on the ASD relay. On newer models that will occur and the engine will still run if the cam sensor fails but the crank sensor has to work. On older models both sensors have to work for the relay to turn on. I'm not sure where a 2001 falls in there.
Be aware too that if you remove the crank sensor, it requires a paper spacer to be stuck to the end of it when reinstalling it to set the air gap. If you just shove it in all the way and pull it back a little, you'll have no idea what the gap is. I got stung by doing that once. If you stuff it in all the way without a spacer, it can hit the ring on the flex plate and break.
