[Delearious02]

Ok so I have been searching for hours and I have done sooooo many things I have been around srs for years have done a half dozen swaps. This motor was in a car that ran it's a** off until it hit a car at 5 mph and it started up after. So I pulled the motor and put it into my car that has had a sr in it since 06 both s13 sr20dets I have checked compression fuel and spark it turns over perfect just doesn't even try To start turns over great so I swapped cas ignitors and spark plugs checked and rechecked grounds checked timing I just don't understand they where both running can anyone help meeeeeeeeee pleaseeeeeee it's a 1990 hatch with basic mods fmic bov both s13 sr20s fuel is getting to plug I can smell it and spark seems like it has strong spark I also swapped ecus and rechecked wiring is there any key grounds ? I checked the 3 on the back of the valve cover and other major grounds I could see please help me. Text me at 8046155224 if u have questions to help me I will pay via paypal if someone helps me get it running

Ok so its still not running but i have swapped out sparkplugs and cas. I have fuel and it backfired 2 times today. I was thinking i would throw out that the motor that is in it now is a blacktop im 90% sure its a s13 sr so the wireing should be the exact same right???

If it backfired than you have a timing issue. Rather your cas is stabbed wrong or a cam jumped a tooth. Could possibly be start signal. Btw don't post you will pay up if you don't even answer your text message.

I am 90% sure the cas is not timed correctly with the motor going to reset timing tomorrow
