SOURCE: F250 Ford 7.3 L Powerstroke Hard to Start Cold

I have a 2000 F250 with Powerstroke and my buddy has a 02 with same engine. Both of us have had the same problem. There are two coils (look like starter coils) on top of the engine that can be seen from the passenger side of the truck. The shorter of the two, has to do with supplying voltage to the glow plugs. When this coil gets older, it breaks down causing a higher resistance in the circuit. Which reduces the volts that the glow plugs see. In turn resembles a problem with the plugs. My buddy and I changed the coils and both trucks start like new. The part cost $80-$90. and can be changed in less than 5 minutes. Glow plugs are a lot bigger job and more expensive.

SOURCE: we think it is the diesel injection pump but not sure

Sounds like not all the glow plugs are working.It should run fairly smooth on a cold start if all of the glow plugs are working..Also you shouldn't drive off on a cold start with a diesel,Its really hard on the motors..At least give them 10 to 15 min on a cold start..The oil in them is a really thick oil and when there drove on a cold start theres no oil lubricating the internal parts and will cause the motor to seize up..You may already no this and dont mean you drive it as soon as you start it i just wanted to let you know..When you get alot of white smoke it could be two things,Theres water in the fuel which will make it not have much power die and smoke..But if it runs fine when its warm theres some bad glow plugs...Hope this helps you and have a great day

SOURCE: 1996 f250 7.3 powerstroke has rough idle on starts

it sounds like to that it is either worn/ old injectors,dirtly HPOP (high pressure oil pump) oil worn HPOP pump or dirty fuel filters or fuel. you can take truck to a qualified diesel shop and they can do a buzz test on your injectors and see if they need to be replaced with a buzz test the tester will buzz all eight injectors with engine off and you can hear the buzz of the injectors then it will go through and buzz each injectors individually in firing order to der determin witch ones are bad. the bad injectors will be alot quieter than the other and most testing equipent will show what they are running at. hope this helps.

SOURCE: 1996 F250 powerstroke 7.3L keeps dying

It is sometimes difficult to determine exactly what is wrong with the 7.3L engines. Many times it is hit and miss for the do-it-yourselfer. It sounds like you are getting enough fuel at first and then fuel is being constricted. You might want to try changing the fuel filter. Sometimes debris becomes lodged in the fuel tank switching valve which would require cleaning the valve or replacing it.

Make sure your plug wires are not being affected (brittle, old,etc}. An engine oil heater works well in cold areas. Possible thickening of oil.

03 ford powerstroke fuel lk. on top of engine, behind the fuel filter housing,fuel sits on top of valley area. can't see any lk. must be slow. cleaned area, can't see any lk.


It ended up being the fuel filter housing drain / shut-off valve. waited for the engine to cool overnight/started engine & rechecked immediatly before engine started warming up & it leaked immediatly. It apparently was a cold only leak. thanks for your attention..

04 f250 diesel cranks but won't start


this is an oil pressure problem, either a sensor is not sensing enough oil pressure, or the high pressure pump is not building enough pressure(possibly leaking or head is leaking). this engine requires 450 psi minimum oil pressure at the injectors to actuate the injectors.

02 F250 Powerstroke almost starting then just chugging


You got a 7.3liter diesel. First thing to do is make sure the oil is at the proper level and if its real dirty change it. Powerstrokes have to have correct oil level to start and it needs to be clean. Next I would change the fuel filter. If it still doesnt start you need to have the fuel psi checked it should be about 60psi key on engine off, 50-55psi running. If that checks correct you will need to hook it up to a diagnostic scanner and scan for codes, you could have an Injector Driver Module failure ($900), or a high psi oil leak in the system (to check that you need to look at the hi psi oil pid it needs to read 600psi to start. These motors are a bit complicated hope I helped some.
