Hello All, I have a 2003 z150txrb HPDI motor that will crank but not fire.
i changed the boat mounted filer, the low pressure filter on the port side of motor and the inline filter after the vst since the boat has not been in use for 4 months. Then when I went to start it would crank but not start.
filter bowl on port side of engine stay only 3/4 full just under the actual filter inside.
vst fills because I can drain it.
for trouble shooting I disconnected the line after the inline filter, after vst and cranked engine, no fuel came out.
I then removed vst.
i then bypassed the port side filter and plugged inlet to filter to inlet of mechanical pump and cranked engine, still no discharge fuel from input line to vst. The mechanical pumps should pump on cranking correct?
pumping the fuel bulb would run fuel out of disconnected vst inlet hose.
took my vst off today to open it up and replace the electric pump filter, any ideas on how I can test vst electric pump while I have it apart in ?
Also what else should I be looking at while I have the vst open?
I’d be interested in any ideas
