I'm going to be like your mother and nag you. Grab the shop manual and start trouble-shooting out of it. Procedures for fixing this or that.

There's a crank sensor too, lower, right, front part of the motor if you're looking at it from the front of the car.
With out inputs from your sensors your computer will not command the ignition coils.

i took my cam sensors out and tried it out on my frinds car and they work fine. tried the coil on plug and they worked fine on his car. the only thing that left is the crank sensor. how do u know if your ecu is busted? can it be the ecu if its not telling the plugs to fire?

Not a code reader but a actual OBD II scan tool that will break down every sensor input for you etc.

I don't know. The ECU could be F'd up and you'd still be able to read it. Say one of the driver transisters went bad, there's no way for the ECU to really tell that it's popped.

I think you're going in the wrong direction. It worked before you pulled the motor out. It should work now. The MOST likely thing is you messed up something during the install. Didn't hook something up, broke a wire, blew a fuse. Something like that.

Without the shop manual, you're just shooting blanks, you should just take it to someone and let them fix it.

Since I have a 'scope, if I was trouble-shooting it, I'd back-probe the harness at the ECU, attempt to crank and make sure the ECU's getting the sensor signals from the cam and crank angle sensors. Without the right tools, you're just playing a guessing game.

can a knock sensor cause a no start condition since it trace back to the ecu when to fire spark? never put mine back b/c it broke when we took the motor out.
