Greetings from Southern Illinois. My name is Bruce and I currently have a Hisun HS550 Performance Rural King. I have had nothing but problems with this unit replaced so many parts of it and of course, it stopped working and will not start again for about the 3rd or 4th time since 2018 it only has a little over 500 miles and has cost me a bunch of money and headache and the Rural King where I purchased it has a repair man who is certified to work on HISUN but he charged me a little over $600 to repair it once back a few years ago and when I got it home after it being in his shop for over 2 weeks the thing worked for a very short time but when I went to start it the next day it was the same thing and they wouldn't check it further without me paying for service, labor, and parts and I went around and around with them and since there aren't any dealer service centers for Hisun near me and even most of them can't get to it for weeks to months and it could be at their shops for months as they tell me they have problems getting the parts needed from Hisun to fix these giant paper weights. Oh, and you can't buy a scan tool (code reader) Delphi 190121 unless you are one of their dealers and I can't find any other scanner tool that works with it except the Tiny Scan Tool which I purchased and it will work if I could find the correct adaptor cable and connector to connect the Tiny Scan to the diagnostic port on the Hisun HS550 Performance Rural King. Yep, I pretty much have been screwed every which way that can happen with this machine. I am disabled, have cancer, and am on a fixed income so I need help if anyone knows what the connector is called (type or part name) that will plug into the diagnostic port to get my scanner to work it is a 6-pin connector and I hear it only has to have 3 wires connected to it.
I have a 2012 Massimo MSU 500 that died. I found that it didn't have spark and the fuel pump wouldn't run. Checked all fuses and none were blown.
Went through and replaced the ignition coil, HT lead and spark plug. Still no spark.
Thought it could be the fuse/relay box because I didnt' know much about the machine at that point so I replaced it. No spark.
Then I replaced the ECM just because I was running out of ideas. No spark.
I removed the 9 pin connector and hardwired it making sure that they were no wires got swapped. Still no spark.
Then I replaced the wiring hardness. In doing so, I replaced the 9 pin connector with new ones. I made sure all wires were matched up between the engine harness side and the other harness assembly. Still no spark.
I have no other ideas what to do. My fuel pump doesn't kick on and I have no spark. I have 12V on the fuel pump, ignition coil and fuel injector, but no ground from the ECM control. I unplugged the fuel injector and waited for a diagnostic code but nothing ever came in. It makes me think that the ECM isn't powering up. I've checked for 12V on pins 18 (purple wire) and 15 (white and black wire). I also checked for ground on pin 2 (black wire). All are good.
I am out of options here and I have no idea what else it could be. I have all connections redone and are coated with dielectric grease. I've checked all easy things like fuses and making sure I have 12V in the right placed. I would appreciate any help.
I installed a new GY6 150cc engine in a Bull Dog Pup 200 and when I put it in drive, it grinds for a second and then runs fine. Works great when i place it in reverse. Could it be from it idling too high? Any help would be greatly appreciated.
