I still am messing with this no start problem, but now I can't even get the car to start at any time. I thought it might of been the dme relay, but I jumped it according to clarks garage. When the key is in the on position I am getting +12 volts to the coil, but when I try and start it I only get around 8 volts and it jumps around a lot but never goes above 9. I think this could be my problem because I am getting no spark from the coil.

bump... (please help)

hrsteel

Is the battery up to snuff?

Lechto

brand new battery

Lechto

new coil, plugs, wires, distributor, rotor, speed/reference sensors, used/new engine wiring harness

hrsteel

Does the motor turn over like normal, but fail to fire?

Lechto

ya, no problem turning over but just won't start.

hrsteel

How did you verify that you are getting no spark?

Lechto

I used 2 separate spark testors and then a timing light

hrsteel

Did you check on the coil side of the distributer or the plug side?

Lechto

plug side and then the coil side

hrsteel

Have you checked the resistance across the coils? New parts can be defective.

Lechto

Yes, the coil checked out perfect. It just isn't getting enough power when I am trying to start the car.

Lechto

I gotta go, but I will be on tomorrow so everyone please give me some input as this problem has been with this car for a little over a year. I need to get this fixed before I go back to school the 16th. Thanks for you help

8v or 9v is a bit low, but not horrendously so. You should still be getting a weak spark out of the coil. Starting voltage typically reads low because the battery cannot supply enough current to keep the system at 12v while driving the starter motor. You could isolate the starting system by spooling up the motor with the key in the "run" position. The easiest way to do this typically is by rolling the car down a hill. God help you if that doesn't work and you can't tow it back up the hill into the garage. Alternatively, you could drive the starter "manually" with a spare battery and some jumper cables. That should completely isolate whether this is a staring or running issue.
