Well now i could use a lil help... i have a trooper in my shop now that has wiring issues... this poor guy paid another shop $1000 to re wire the body control harness, and boy oh boy did they chop it up!!! I am Buillding a new harness from scratch... what i need is a diagram that tells me what each fuse and relay control on the Engine fuse/relay block.. any help is greatly appreciated!!
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.
Hi all have a issue with non start
Turns over happily, can smell fuel when crank and have check the injector is fireing. The spark seems weak and spraying easy start down the intake it won't even cough. Have checked all wiring and repair some dodgy bits, now thinking the pick up Coil maybe bad . Check the manual and it gives a resistance of 459 to 561ohms as spec, mine is reading 204.
Would this indicate a bad pick up Coil and cause the no start, weak spark?
Would the lower reading resistance alter the spark timing?
Ready to burn the thing at the moment lol
