CARTOYZ

An update. I put a scanner on the beast and came up with code P1690. when I looked it up it is telling me the crank position sensor does not agree with pump. I have only seen engine light on once and engine was running. Any thought?

Yes the tach does work, However it has quit a couple times and comes back, Also, . when I left it 8 days ago it wouldn't start and havn't move the truck a inch and went out just now and fired right up. wth?. Can I mount a fuel pressure gauge on top of fuel filter housing? I am thinking I am not losing prime as it started, and it was parked on level ground.

99 2500 Ram. Pick up was parked all winter,went to start and just cranked over, shot it with either and started up and was good,thought just lost pressure. Then, at station getting fuel and same thing. I replaced full pump on block thinking that was it and get still does it. Dan a power wire to pump to toggle pump on but still does it with pump runnnning, Abby very annoying. I am thinking it is the control box on the side of block in front of pump. Anyone agree. This is intermittent and can go weeks and be fine. It will always start with a shot of juice. Any ideas
