I have a 2000 cherokee it will not start i have put a crank position sensor in it asd fuse went through my whole harness looking for cut wires/burned everything is fine...cleaned all my grounds checked every fuse there all fine i have no spark but i have fuel to the rail but the injectors alone are not pulsin i need help asap i have searched everywere but no help

 

Have you tried swapping the ASD relay with another? Checking for power @ the ASD relay socket?

 

i switched the asd relay with one from a friends car and it worked but no i havent checked to see if there is power at the relay socket.

 

The fuel pump spins up when you turn the key on, I assume? You should be able to hear it.
How are the plugs and connectors @ the ECU?
How are you checking the injectors to determine no pulse?

 

fuel pump comes on the connetors are good the ecu is grounded i have to check the voltage on the injector plugs again to make sure...but it want come through any of the injectors take the injector off it shoots out like there aint no tomorrow

 

That's what I'm wondering how you are determining. Do you hear/feel the injectors clicking? Any sign of fuel on the plugs when you pull them? Not asking to second-guess you, just that missing spark might lead down one path while missing spark AND missing fuel down another.

 

"but it want come through any of the injectors take the injector off it shoots out like there aint no tomorrow"

Confusing statement.

If the engine won't start (No Spark/Fuel), the fuel injectors, igntion coil pack, and O2S heaters won't work because the PCM hasn't received a signal from the ASD relay (The ASD Relay activates these items) that it has been activated through the crankshaft position sensor.

The PCM won't activate the ASD unless it receives a signal from the crank sensor that the engine is rotating.

Was the crank sensor you installed an OEM sensor? Some aftermarket crank sensors fail right out of the box.

 

i will check here in 10min to see...

 

the crank sensor is from napa....i had a 95 xj that had no spark put a crank sensor in it didnt start switched the asd relay and it cranked right up is there a way to check the cps to see if it works

 

my injectors have 9.4 volts my cam sensor has 12 the coils pack has 10 crank sensor has 11volts

 

What worked? the relay, problem was fixed or ??? I guess question number 1 would be what are the codes?

If all the wiring is intact, you might just have to get a mopar CPS.
