She Won't Start!!! Need Help!!!!!!

[HSkinner]

I've got everything ready to go and I've got power to the injection pump when the key is turned on. I bled the fuel out of the return side of the fuel line. I turned it over and got fuel to come out of the top of the injectors then I tightened the injectors. I used a little starter fluid in the turbo and it will run long enought to burn off the fluid but it won't stay running. Will the starter fluid hurt anything? Also, There is an aftermarket fuel pump feeding the injection pump and it seems to be pushing the fuel more than the injection pump. IS this hurtung anything??? It also seems like it's not building up a whole lot of oil pressure. The motor has very low miles but has been sitting for a while but ran fine before it was pulled. I emptied the fuel filter and tried to get the old fuel out then change the oil but I can't get it to stay running without the starter fluid. What am I doing wrong???? :{#@$%!:{

Is it a VE or a P-Pump? If it's a VE, are you sure the plunger is moving in the shutoff solenoid? It could be stuck down from sitting.

If it's a p-pump, is the solenoid moving the lever when you hit the starter? If not, turn on the key, move the lever up, it should stick. Then try it.

If you have fuel to the injectors, it should start, no ether needed.

On the ether, I hope you don't have grid heaters! The ether isn't good for it long term, but a little should be ok. Don't shoot so much in there it locks up. I would look closely at the shut off system before I used more ether. JMO

 

[HSkinner]

Sorry, It's a VE Pump and it does have the grid heater but it's not hooked up. I'm not following you on the plunger. Wouldnt it still start even if the shut off solenoid wasn't working? How do I check if it is?

spray WD40 for starting fluid or use both at the same time or deisel in a spray bottel

spray WD40 for starting fluid

yes. . this always works and is safe. (works for gas engines also... )

 

[JLEONARD]

The shut off solenoid is in the closed position with no power applied. Apply power and the plungers lifts to allow fuel to flow thru ther injection pump.

On a VE this is all inside the brass solenoid... you cannot see if the plunger is moving. You would need to remove the part to see if it's stuck closed.



However... . if you use a test wire, clip it on the solenoid blade, then touch the battery Pos with the test wire, you can hear the solenoid clicking (plunger moving) if you listen very carefully and there is no surrounding noise. (at least I can hear mine)

 

[PToombs]

Jay covered it real good. That's what I would do. If you don't hear/feel it click, pull the solenoid and remove the plunger and spring. Put the solenoid back in, and try to start it.

It does have the shutoff lever on the side of the pump right? If not, you may have to stall it to shut it off.

 

[HSkinner]

What about the fuel pump. Do I need to bypass this. Is it possible that the fuel pump is pushing to much fuel through the injection pump? Also, How quick should the oil pressure go up? Does Diesel go bad? Is it possible that the diesel that's in it is bad?

 

[PToombs]

There are check valves in the stock LP. The electric should push thru. It can't push to much, there is an orifice in the return banjo bolt. This helps keep a certain pressure in the pump. Oil pressure should come up in 5-10 seconds or thereabouts. Do you have a mechanical guage? It may need to be bled. If the stock electric, I wouldn't trust it too far.

Diesel can go bad, but I think it takes a while. I bought a truck that had been sitting for 4-5 years. I pumped the primer, it spun about twice and started up. Then when it got cold, it kept freezing up. I pulled the tank and it was full of algae and water.

 

[HSkinner]

Thanks for the info. I may need to bleed the mechanical gauge. I was worried about the fuel that was left in the motor. I replaced the gas tanks and all of the fuel lines but I'm sure there was a little left in the IP ad the lines. If the Plunger is stuck how do I break it loose?

 

[PToombs]

I haven't heard of one sticking, but I know there's a 1st time for everything! Just reach in with needle nose pliers, and pull it out. The spring drops down inside the plunger, it's hollow part way. I'd just remove it and try to start it.

Good luck!

 

[HSkinner]

I noticed that I had fuel bubbling at the injectors when the fuel pump came on and built some pressure. Is it hurting the VE IP to push through it like that. I know you already kind of answered the question, but someone told me that with the VE pump it shouldn't have to much pressure or it can push fuel in to the oil pan.

 

[PToombs]

The VE doesn't like more than 15-16 psi. Much more and the front seal leaks or blows right out. Then you're pulling the pump and resealing it.

Maybe plumb in a guage and check pressure? Or just run the stock LP for now.

Did you get it to run?

 

[HSkinner]

I've done everything that everyone has said to do including pulling the plunger and spring and it won't stay running without starter fluid. It did build oil pressure but that's it. I cracked the injectors and bled them for probably 30 seconds and it 's getting plenty of fuel but still won't stay running without starter fluid. What else could it possibly be?

I bet you had what happend to my suburban , the engine sat around and got water in the pump some how and rusted up the inside of it , mine would run as well like that but it pump raw fuel out the dump tube i had on it to fire it up , id say pull the pump off and have it checked along with your injectors

 

[PToombs]

If you have fuel and no fire, I would have to agree with DV. Pull the pump and injectors and have them tested. It should fire right up.

Did you have the pump off before? Could the timing be off? That's the only other thing I can think of.

Other than that, I don't have a clue. I work on these things most everyday, and it's rare they don't start. It's also tough troubleshooting long distance.

 

[CumminsDoofus]

I don't know if this will help you but I scrounged around in my computer and uploaded a vid of how far the fuel should squirt on a stock pump. I would check yours to see if it shoots fuel about the same distance before removing the pump. Yours should be about the same It can be hard to tell how much fuel you have moving through the pump by just cracking the lines at the injector's

 

[HSkinner]

I removed the solenoid plunger and turned off the power to the fuel pump trying to verify how much pressure the injection pump is getting to the injectors and there was very little fuel at the injectors when I cracked them. When I turn the aftermarket fuel pump back on I get the fuel leaking out of the injectors. Is it possible that the lift pump is not working? OR does this ultimately confirm my injection pump is bad? Where is the best place to get a Bosch pump and whats the differenc between the intercooled and non-intercooled pumps? I need one ASAP but Don't wan't to go broke getting it?

If your getting strait fuel running out the injectors you have a injector pump problem period , it should not just run out at all ,it should squirt , not run out period . If you think the lift pump is bad get a electric pump a cheapy will work and hook it on line or a can of fuel with a sqeeze type bulb on it if its that it will fire , al though it should fire on with WD40 and keep running with out going wild .



There is no diffrence on a intercooled and non intercooled injector pump , on the injectors there is a slight diffrence on the nozzels were a adapter is needed to run newer injectors on the non intercooled engines
