I had mine to shut off multiple times like I cut it off. Left me sitting and playing around with wire and stuff. I replaced pmd and cranked ran fine for 3 miles then shut off. New pmd was crap bought another one from a different company and has ran fine after that.95 6.5l I put a new pmd in and new lift pump. Took it awhile to start got it started drove it around a bit. Then I went to clean up mess from working on it left it idiling. Then I heard it die and wouldn't start backup pushed it back in then it started. It will idle for 1-2 then die restart idles for 30 seconds then dies and wont restart and doesn't smoke very much. Any tips would be nice I have a fuel sending unit for it also cuz my fuel guage doesn't work.(edit I drove it home before this all happened ran fine sat for 2days then gp wouldn't cycle and wouldn't start
A PMD can mimic that same issue.It seems like air tho cuz when it dies it won't restart then after it sits ir fires right up
I have the fuel tank down right now when I get it back in there I'll try that stuff. I really hope it isn't the ip I don't feel like putting that much money into it lolA PMD can mimic that same issue.
IF the transistors in the PMD are overheated you can get a no start condition until the transistors cool down.
Also a worn Injection pump can do the same thing.
Once the internals of the IP heat up they can move out of tolerance specifications but once it cools down it will allow fuel to flow through the IP.
(To test the IP theory once you get a warm no start condition)
Grab a small bottle of room temp water and pour it over the Injection pump.
Attempt to start. If it fires right up that is a sign of a worn injection pump
Air wo nt dissappear on its own, had same issue and was a weak pmd
I bought a new one ,lasted 3 miles . Sent it back for refund and bought one from a different company. No problem after that.Do u think I got a bad pmd I already put a new one on it but it was just an Amazon special
