84 Eagle runs great but then will not restart unless I reset computer
(1/1)
echeever:
Hi all-I finally got my 1984 Eagle wagon on the road and have been driving it to work. I picked up the car last November and have replaced the 258 with a running used engine, new fuel tank, ECM, re-ran all vacuum lines, went through carb, etc. Generally the car has been running well but one problem perplexes me. I can drive it for miles and miles just fine but when I go to restart it will sometimes fire up and then die as if the timing is radically thrown out of wack. I then need to disconnect the battery for a minute and it will start and run just fine again. Very annoying. Has anyone had the same problem or have any ideas??? Thanks for any thoughts!
MIPS:
The computer shouldn't have any sort of memory or standby power so disconnecting the battery won't do anything. Unless the key is in the ON position it's completely unpowered. Is the ignition module/starter ballast the original or did you install a new one as well? I've seen those fail once warmed up.
echeever:
Hi MIPS, thanks for the reply. The ignition module is brand new. That's not to say that it couldn't be defective.
echeever:
Well, looks like I have to do an ECM test. Timing is definitely being effected. I am used to working on pre 1970 stuff, this is a whole new world!

My personal experience has convinced me that 20% to 25% of new modules are no good! Been there; done that (and keep a known good spare module in my car at all times!).
