Definitely start w electrical, go to fuel psi at proper locations & make sure PSI is not bleeding down after ignition is off If so you found the main problem. Now find out where it's losing PSI to. (leak, regulator, injector etc )

SOURCE: 1995 Dodge Ram 1500 2WD 5.9L fuel pump or???

Code 12 doesn't correlate, but Code 1282 may provide some insight. Code 1282 is "The fuel pump relay circuit seems to be having a problem", which would explain the disconnect/reconnect trick that sporadically works. Have the relay circuit looked at.

SOURCE: dodge cummins won't start, fuel reaching injector pump but no fuel coming out of injector pump.

You said you have fuel flowing from the inlet line of the injection pump? But not at the injector lines?

SOURCE: 1999 dodge ram 3500 cummings turbo diesel will not start.

Diesel engines fire on compression alone (usually 400psi).The Truck may have air trapped in the fuel system.When you perform any fuel system repair on a diesel it is going to take alot of cranking to get the air out. You can take the breather loose and shoot a VERY small amount of starter fluid in the intake and it should start. Do not use starting fluid much as it can damage the engine. Good Luck.

The "wait to start" light is your glow plugs. You must have a loose connection to them or something not connecting. They come on almost everytime you start them, hot or cold.

Got a 97 jimmy fuel pump is good filter is good, but still cant get it to run


Then one of your statements must not be true. the fuel pump usually is ran by a relay off the oil pressure switch, so if engine stalls fuel pump turns off. There is relay as well. Follow wiring from pump to relay,
if it only starts when primed, then fuel pump must not be getting power at all, suggesting relay, or fuse.
the fuel pump should be audible when key is turned on, shortly then it turns off.

I have nissan np300 zd30 engine its nt supplying fuel t e engine,have t prime harder for it to starter n after starting,if l stop priming t wl cut off.what cld b e problem


?? depending on year ,,,it could have a lift fuel pump in the tank to prime it up for starting ,providing its a conventional injector pump which having a hand primer i would assume it has ,need more info really but do check the fuel lines on the top of the fuel tank as they could be perished so its sucking in air ...or the lift pump inside the injector pump has failed ,really need to see it to know the problem .

Engine cranks but doesn't start. Guess there is no fuel for the injectors. Injectors checked, new spark plugs, car has 170K miles.


Is there a fuse for the fuel pump? I'd start there. Then check the wiring for continuity(broken wire).

12ht wont prime


filling the filters before installing will make priming go more quickly.
once the pump is primed crack open the fuse line at the injector while cranking until you have fuel pulsing out, close it then move on to the next injector.
keep doing this until the engine runs smoothly.
it may start running before all the injectors have been purged so keep clear of all moving parts and a fire extinguisher handy would be a good idea.

I have a 1989 iroc camero that will not start.it has a throttle body carb and is a 305.the fuel pump works fine.the car will start if you prime it,but otherwise it wont fire at all.it has power on one wire...


Although you Say the Fuel Pump is Fine, What you Discribe is A NO FUEL Problem If it Starts When Priming and Does Not Without Prime this IS a Fuel Pump Problem NOTE: If you HEAR the Fuel Pump this only Indicates that the MOTOR that Drives the Fuel Pump Works , A Fuel Puessure Test Will Determine if your Fuel Pump In FACT DOES Work.

Old j reg mercedes 230te wont start


Check Injectors spraying Fuel when you start. Fuel pump prime because you hear the pump. IF pump is weak, then your Fuel distributor doesn't have correct pressure to spray fuel when injectors open. Do your sparks plug wet after trying several times. If they are dry then you don't have fuel. Replace injectors If they are wet then you don't have correct air:gas ratio of 14.6:1. Replace Fuel distributors

1999 dodge ram 2500 5.9 cummins diesel.won't start.turns over thats it. put in a new intake fuel pump. still won't start.got fuel to the injectors sometimes.


Check the fuel pressure at the filter. Odds are the lift pump, located below the filter, is toast. Continual cranking of the motor with a bad LP wil cause the injector pump to heat up and burn out. Replace the LP and fuel filter. Bleed the system by cracking the inlet to the injector pump and bumping the enigine over so the LP will run. Once you have fuel at the injector pump, crack injectors 1,3,and 4. Crank the motor for no more 6 or 7 seconds at a time until it turns over. Give the pump time to cool for a couple of mintues between cranks. This process is easier with two people, one to crank and the other to watch for fuel and tighten the injectors once it starts. If the injector pump is fried at this point from cranking with no fuel, the motor should idle, but will stumble all over itself when the throttle is applied.

Starts then quits


Try the ignition control module located under the distributor cap $30 - $60. This is one of two parts on this truck that will cause it to not run or shut down after running for only a short time. The other is the fuel pump I think it is safe to rule that out as your problem
