ok, i have a 95 eagle talon esi atx. i have had the computer checked 3 times and no problem. i changed the crank sensor and pigtail due to corroded wire that broke off. i checked the whole harness and all the wires are good. i checked relays and those are good. we had to change the motor cuz we spun a rod bearing. same motor but from 97 avenger. car ran perfect for a year after but then comp went out and now wont start. out of options

Do you have 12v at the coil pack while cranking?
IF you dont that means the ASD is not actuating.
IF that is the case you need to check signal from the crank and cam sensor. 3 wire sensor has a ground, 9v power and a signal wire the ECU. Verify your power and ground first. If that checks out good you want to verify the signal wire continuity (wire end to end and end to ground)to the ECU to verify the wire isnt shorted or broken.
If the Coil is getting 12v while cranking then probe the ECU wires for a ground pulse.
Check to see if your getting injector pulse. Use a test light or a noid light.

i checked everything 2 or 3 times. i get voltages and everything when i first turn on the ignition and then nothing. but when i try to do anything as far as cranking the motor, i lose it all. as if the ecu shuts down totally. and i looked at the pin set-up for the ecu and my wires are in reverse from the diagram.

OK, lets get something straight. you asked for help. Your reply is i checked everything....was my question "did you check everything"? You havent answered my question when you reply so vaguely. If your not going to do what i have told you then dont bother asking.
1. When powered up the ECU will power the ASD then after 15 secs power the ASD down. 2. When the ECU going into cranking mode it will power the ASD up.
Your telling me when cranking you have no power to the sensors which means you have a bad ECU or power to the ECU.

check your battery terminals. my car used to do that too. in ACC mode dash lights would light up, go to start, nothing. first thing i thought when seeing this on twitter was to check the ASD. Ive had issues with that relay and the FPR. wouldnt hurt to check it again...

ok. i check all the power coming from ecu when i first turn ignition on. it continues to send power for long periods of time. even after a few minutes i can still get voltage to all my sensors. as soon as i try to start the car i lose every bit of power to the sensors and never get voltage to coil pack or injectors.the ecu is good because 3 techs looked at it the last time to verify that it was working properly. this morning i took out the harness and checked for continuity in all the wires. i found that there were ground wires that were messed up and replaced those. i looked at the pin diagram for the ecu and noticed that my factory harness is reverse wired from it. middle row is identical but outside rows are switched. pin 1 on diagram is in 41 on harness and so on.could this be the issue?

Well if three techs looked at it and ignored the fact you have no power to the sensors then I guess they are not checking it correctly.
If you never get power to the coil pack even when cranking then remove the ASD and jumper the socket. Use the schematic, i dont know wire colors off the top of my head right now. When jumpered you will have 12v to the coil and injectors at all times so dont leave the jumper in if you give up testing for the day. Your relays might be good but the harness or socket might not.
If you jumper the asd and you still dont get power to the coil then you know you hve a harness issue. Either your not getting 12v tot he asd socket or the wire coming out of the socket that goes to the Coil and injectors is broken somewhere.
Take the schematic and make sure all the 12v power wires going to the ECU are good and verify all the ground wires have a sufficient ground.

no injector pulse, no coil signal. did check signal coming from crank sensor and showing 9 volts. possible bad sensor even tho that was just replaced recently?
