NOW I do. I need other stuff before another car to be honest. I would just trade straight up my eclipse for this, but mines running and his is not.

Could just be a crankshaft position sensor. He mentions replacing the cam sensor but not the crank. Its not a hard fix if that is what it is.

Snatch! Yoink! Grab!
If it was around here, I would have already bought that sucker. I need a donor 420a engine to build, and $300 - $500 would be SWEET. Then I stuff my old motor in that car, after my build, and give it to my wife. hehe

I have the crank no spark problem too and I have replace both relays, the crank sensor, sam sensor, and the computer and still no fire. The kool thing is that I have spark, and fuel pressure until I start cranking it. As soon as I do, No spark, No fuel pressure. any one have any ideas?

This might be way out there but what kind of condition is your battery in? When you crank over your car the starter takes a lot of power. It could very be possible that your battery is just to a point where when you crank the car over it doesn't have enough power to run your fuel pump or spark your coil. As I said it might be way out there but it might be a possibility.

new battery was installed, a while back and the problem remained :puzzled:
Also had it at the dealership and came up with nothing, Im open to ideas. At this point I am on the verge of a new crate motor, wire harness, and all new sensors.

check to see if the fuel pump come on when the key is turned to run. if it doenst then its the ecu. i just went through the same exact problem. it would crank fine but there was no spark or fuel pressure. when i replaced with a junkyard ecu she fired right up.
