Hello, i have a Linhai 550 4x4 from 2017 or 2018 and i have a problem with starting the engine
The Relay pump doesn't seem to stay long enough.
Sometimes after playing with the starter relay the relay pump works good, it starts but when i try to go it stops after 50 m, any idea what's wrong?
I think it's beacuse of the wiring
here is the plug for the relay, im waiting to switch

 

Change the spark plug, you never know, it could be a faulty plug. It looks like that spade connector has been changed, and that it has been getting hot. Clean it up and check it is crimped correctly. Check and clean the fuel filters, there will be one on the suction side of the fuel pump and a tiny one in the injector, this I blow out with compressed air. If these changes don't fix it, your fuel pump could be giving trouble. Generic pumps are cheap but you may have problems finding the right one for a Linhai, if the genuine pump is difficult to get, or expensive.

 

Already checked the spark plug and it's all right
I will clean the fuel filters and change some wires from the starter relay and update you if it works more than 1 day

Thanks for the tips
