Got engine in, got fuel but no spark. I tried my old crx dizzy and the car started for about 5 seconds and died. No spark again. Anyone had a similiar problem that can help? All grounds are connected and tested. The ls dizzy looks brand new, like it's never been used.

 

does the ecu have a solid light on all the time?

 

no cel light, dunno what happened i got it started though had, was having no spark like the coil was out then I switched dizzys again and it decided to work, wierd thing.

 

Check all your grounds. Mine did this when my ecu ground was loose (ground by the thermostat)
I also had a problem with my main fuse giving me fits.

 

I actually checked and tested my grounds with a multimeter and all looked good, I really have no clue what was causing my no spark.
