Help - 97 3.9L Won't Start...
My 97 DAK won't start. It drove just fine a couple days ago when I last parked it. But went I got in it yesterday morning she wouldn't start. Turn's over fine, has plenty of gas in the tank. I figured it was the fuel pump quit me so I shot some Ether in the throttle body to see if she would hit -- nothing!
I next checked for fire by arcing across the top of the coil to ground...got a really weak spark is all. I figured I should have a big strong blue spark here???
Anyhow, I'm wondering what else I should check here? Could it be a bad Coil? Distributor problem? Any ideas on next steps?
Thanks

I would check the grounds , I had a similar thing happen to me and it was a bad ground from the motor to the body, replaced it with a nice thick cable and I was back in business. Next I would pull a plug wire off a spark plug and have someone turn it over while you look to see if your getting any spark when your hold the wire end next to the block,or body just don't get shocked it doesn't feel nice haha hold the wire back from the end a bit or it will jump to you if your leaning on the truck.
Does it stay running if I gas it??? It doesn't run at all even when I shoot ether down the throttle bottle. I don't suspect it to be a fuel issue for that reason.
I'll check the ground strap out. I may throw a jumper cable on from the frame to the motor to see if that works. I recently had a mechanic replace a push rod in this motor so its quite possible the ground wire came loose -- particularly if the ground wire is bolted to the intake since that was pulled off.
If that doesn't do it, I'll do the plug wire arc check you suggested.
