Intermediate Spark Issue

[deank1]

Before anyone says it, yes I have searched and I have done my research on this subject. My problem however I cannot figure out.

I installed a rebuilt 95 420a into my 98 eclipse. It is 100% hooked up with a new crank angle sensor, Cam position sensor, and many other new sensors. I am having trouble getting power to the coil pack. When I turn the key to the on position, I am getting the CEL and the other lights and when crank I have no movement on the tach.

Last night i was doing a little digging in the car and took the battery out. I checked for obvious things like the EGR burning the wires and such. I hooked the battery back up and had power to the coil for appx 5 minutes. Then it was dead again. I only get power to the coil in the first 5 or so minutes that the battery is in the car, then it looses it.

Can anyone help?

I am using an engine harness from a 98 which came with the car. I am using a 98 5 speed transmission and a 95 motor. All the sensors that needed to be swapped to the 98 style have been so.

Ok so I have signal to the two outer wires and 12v constant to the center and still no spark. I have checked it with new coil pack and nothing. Can anyone help?

Check here 2GNT.com - ECU_Pinout and see If your getting the right voltages out of the ecu. If they are good coming out and not at the sensors then the problem will be a short or bad asd/fuel pump relay. Hope this helps a bit more
