the starter turns? I'm thinking that you have not got a NEW battery and new cables that have NO corrosion...one can easily forget the black cable to the frame/chassis....AND the bolt on the motorblock...these have to be clean, free of corrosion and happy with 50 amps~ also computers and soleniods prefer at or Above 12.5 volts...and at least grabbin at 50 amps ....would suggest a load test of your existing battery but LEAD batteries would recover easily...Tin/Antimony alloy batteries STOP taking a charge 10 percent per year and degrade to an unreliable state in short time~ what I think is that you've not the muscle, electrically...smarten this up!~

yeah, you are starting to see the problem that so many people face these days- complicated 21st Century cars with a zillion parts to go wrong, and being poverty stricken- myself, I am working on this unpleasant situation by owning a simple, old machine- and riding a bicycle- good luck- keep trying, hope you figure it out- or just scrap the junk and start over-

Well you are going to have to go over the basics, make sure there is the proper fuel pressure, spark to the plugs, & the timing set correctly.

Re-reading your post, is this a rebuilt engine? or some junker you found. Check the compression on the cylinders.
