420A No spark but fuel

[1996Eclipse420a]

I know this has been beat numerous times but I need help. My car as stated above has fuel but will not fire at all. The way our cars work is the coil gets a signal from the cam and crank position sensor correct in order for there to be spark. I've replaced the cam sensor to find out it still won't work... My question is... what voltage should I be reading at the coil pack plug, and at the cam sensor plug. The asd relay is working fine.

I think there may be a wiring problem but I'm not sure. I drove it home from school last night and it ran fine... and this morning it won't start at all. That's why I think there is a broken wire somewhere.

Have you checked timing to see if it jumped a tooth? Happen to me the same way I drove it the day before drove home and parked it. The next morning woke up to go to church and my car wouldn't start. I tried a few times then just took my other car. Later after going thru my no start check list I discovered my belt jumped a tooth. Thank God it didn't damage anything and only gave me a no start condition. Anyway after changing all the timing components the car fired right back up! Just something you might wanna check before digging to deep or swapping to many parts! Also as you mentioned if you suspect faulty wiring then fix it asap or check it over good to rule it out.

My timing is spot on. I'm not getting constant voltage to the coil pack. I have voltage running to the ASD relay though, but none at the coil pack... Should these cars see a certain amount of voltage with the key "ON" at the cam sensor too? I get 5v reference at the cam sensor (i forget what pin it's on) but I don't have a constant voltage. I do know for a fact that i don't have constant voltage going to the coil and from what I've read pin 2 should see 12v, and pin 1 and 3 should pulse when cranking.

Sounds like it could be the ecu possible. There should be a reference voltage at the cam sensor and definetly voltage at the coil!
