Hi, got a parweld xts 143 that I've only ever ran 6013s on. Noticed in the manual the ocv is 50v and I'm wanting to try some 7018s. Will 50v manage them? Thanks.
Definitely worth trying a leak off test while cranking. My bet is on one or more of the injectors being naff and not allowing the rail to pressure up enough to start.
A squirt of easy start usually gets the engine spinning fast enough to build the pressure up enough and get it to start.
