Hey guys I’m new to this forum and a (what I believe to be a) roketa gk40 with the fuel injected 3cyl engine. I bought it after it had been sitting for a number of years and after draining the fuel, cleaning and testing the fuel pump & injectors I cant seem to get it running, It has 185/190psi compression, has spark, has fuel but won’t start. Can’t even get it to fire off of starting fluid. I don’t know the units history and I can’t seem to find any info/schematics/manuals online. I’m questioning a computer issue. Any suggestions? Thanks in advance.

At this point I’m looking to buy a running buggy with the same engine just so I can figure out what the issue is with this buggy haha So if anyone within a reasonable distance from St Paul MN has a 800cc efi buggy for sale message me haha

If you have fuel, air, spark and compression, the only thing I can think of would be the plug wires are in the wrong order or your timing is way out of wack. Look at Suzuki F8B engines for better references. Even though most were carbureted, you should at least be able to find the firing order and how the wires should be run.

I have firing order set to 1-3-2 and 7° btdc And it just spins doesn’t even try to start. Won’t even pop off on ether with injectors unplugged. Is there a link or something to verify ignition timing or wiring diagram or something? All I can find is either in Arabic or a bad link. I’m losing my mind here haha
