Hey all, im having a bit of trouble getting my 7.3 running. Cranks but doesn’t start and no smoke which mean no fuel right? Have a tach signal reads about 150-200 while cranking and i do get fuel from the shrader valve while cranking. Oh and a little back story it had been sitting for about 2+years but started right up when we got it about 6 months ago and never had any issues up until 2 months ago it started taking a little longer to start( took about a minute of cranking) then it wouldn't start at all. Things we have done are new icp sensor, new ipr valve, when it wouldnt start we decided to replace glow plugs and injector o-rings just for fun, the hpop reservoir is about 1 inch from the top. What should i check for next? Any help is appreciated thanks in advance.

 

Take a cheap pencil type tire gauge and check fuel pressure at the Schrader valve while cranking the engine. You should get at least 20lbs. showing on the gauge. The mechanical fuel pump may have quit on you.

Hey thanks for replying, how accurate would that be because i did it and got about 10 psi with a pencil gauge is it worth trying to get a hold of a good fuel pressure tester to double check or should i just buy the fuel pump?

 

Those tire gauges are pretty accurate, 10 lbs. is a little low. Unless you have blockage in the fuel line, I'd say you are due for a new pump.

 

Okay ill try that then thank you
