Just finished installing rebuilt injectors and new sleeves on my 2001 7.3 in an F350. Won't start.

diesels are hard to start if
the crank speed is too slow--- fully charge the batteries
the injector /s /tips need replacing---squirting not atomizing
there is air in the fuel system

well im not to sure do the gauges work and did you check the solenoids for the injectors and the glow plugs and did you check the wiring for the glow plugs and the injectors they are molded into your valve covers and sometimes the tab on the inside of the valve cover breaks off and disconnects the wires

Starting fluid is a bad idea on glow plug engines. Some things to check are, the IDM, TPS, crank sensor, cam sensor, wires running through valve cover gasket, glow plug controller, ECM. Have the codes ran first. Could be one of the fuel pumps, but not common.

Hi Austin, I think you hit the nail right on the head! Replace the glow plugs:-) Regards John

I'd get your injectors rebuilt, and tune up your injector pump. Run a little seafoam in the diesel tank, and in the oil. Should make it clear right up.

I think u shud inspec fuel injector pump-its the heart of a diesel--also do a compression chec--purchase a haynes manual or go to library sec629

I'm going to assume here that you did test the other glow plugs and they are good? How about the fuel filter? Have you checked to make absolutely sure that it is not sucking some air? You do not mention how many miles on this engine. Have you had a compression check done recently? How are the injectors doing? If you want to check them yourself, go get an extra long injection line from wrecking yard or new one and lets call this the "test line".Take out one injector at a time and re-attach it outside, in the open air where you can see the spray pattern. If you can't hook it back up to the same line, try using the test line in it's place. Either hook up a external starter button so you can crank the engine yourself or get some help. You should see a nice fine fog pattern if the injector & pump are good. If the spray is weak or off-center, log it, reinstall it back into engine and move on to the next one. If all injectors show a weak pattern suspect the pump and have it checked. If not, just trade in the bad injectors for rebuilt ones. Nothing wrong with rebuilts. I have used them all the time and much cheaper than new! (rebuilt pumps much cheaper than new as well)! Finally, have you tried to cold-start it with some battery help like a charger that has a start setting on it, or perhaps a buddy that can add a jump start to a running car. Sometimes a weak battery just can't do a good job of glow-plugging followed by spinning the engine over real good. Well, that's my 6 cents work! (more than 2 cents) Let me know how it goes?

this sounds like the high pressure oil pump ( HPOP ) is weak. The HPOP is what fires your injectors. After it starts its building pressure..

remove the inner wheel wells or cut it back to get some access its tight that way though i would just remove the two of them its 10& 11 mm on the top sidde just let everthing hang , it is either 5.5 mm or a 7 mm . the speed sensor is in the transfer case for the 4x4 or on theh rear on the trans for 2wd

Check your battery voltage while cranking. If it's too low, the electronics won't work and the injectors won't fire. If the batteries are down a bit, there won't be enough power to turn the engine over fast enough to start. It needs a minimum of 100 rpm and 8 volts while cranking. You also might try waiting till you're sure the GPR has dropped out. That takes the GP load off the batteries and may get the voltage up enough to get it to start, oh and also does the tach move when you're cranking? If not, then chances are the CPS is the culprit.
