My 99 will not start. Here is how it all went down.. 2 Fridays ago i go out to fire it up to go plowing. It gave me fits since it only has one battery in it. but after an hour i got it running and ran it for 5 hours and nothing seemed out of the norm.. Then a few days later I put in my used motor oil/diesel blend.. approx 15 gallons of blended on top of half tank of regualr diesel.. and I ran it a little bit to move the truck around the driveway but not very long. seemed ok. Then a day or 2 after that I go to start it and nothing, change the fuel filter.. nope. I had and old lift pump i put back on that did work, in which the one on the truck did not anymore.. . Still nothing. I can get fuel out of the 3rd and 4th injector from the front of the engine, but 1,and 2 do not move fuel. but the truck will fire on starter fluid.. Any suggestions ? VP44 junk ? Thanks Ya its my fault probabbly for not havin a fuel pressure gauge .. but this injection pump is not that old or has that many miles on it. I helped the previous owner change it..

 

These engines are diesel engines, they are not multi-fuel military engines. You will not get it started until you drain that crap out of there and get clean fuel up to and through the injection pump. Then and only then will you find out if what you thought was saving you money may have just cost you a 1500.00 pump. Have you tried plugging it in? You have to use two batteries, you will not get enough spin on the starter with one. I hate to tell you this but you are costing yourself more money than you are saving by doing these things. The grid heaters draw 70 - 100 amps out those batteries and one just cannot handle it.

 

If the grid heaters are still hooked up, starter fluid may blow the intake off of it....

Sounds like vp isn't pushing fuel to the other injectors....

 

The grids are not hooked up.. they are on a manual mode now

 

I am wondering if the vp is toast.

What type of filtration are you running for the used motor oil/diesel blend?

Are you prefiltering it before putting it in the truck or relying on the stock fuel filter?

 

One battery, used motor oil for fuel, grids are on manual, used lift pump. You have so many issues here it is going to be very hard to diagnose properly. Used motor oil does not have the cetane value to autoignite at those low temps, I don't care what the blend is. Straight diesel fuel has a hard time with it. It will also have a higher viscosity than the VP44 is designed for.

 

The truck started today.. I think the culprit was some water passed through and into the injection pump. It was 60 degrees today. And i put a bottle of K100 in the tank to eliminate any more problems. Its getting a new fuel delivery system very soon, because the lift pump was actually leaking out the plastic housing . and instead of spending the money on another OE i am going to put something decent on it.

 

What kind of nut are you. These trucks were desigine to run very well the way the are. If you have not screwd up something batteriesi is half your problem. Put in two new 950amp batteries and it should start if you have not scewd or plugged he fuel sustem.

 

To let you KNOW i am not a rookie, and this truck if you seen it has probably out worked a lot of trucks on here.. It was rode hard and put away wet... I modified the battery boxes to accept GROUP 31 battery's, needless to say since the body is in such shitty shape the battery box on the passenger side fell off.... I did get it fixed... thanks for the insult.. And if you weren't so worked up you might have caught the 5 misspelled words in your response ..

 

Guys, he's asking for any help and ideas we may have, not criticism about his truck or himself.

Give him a break, you don't know his situation or why his truck ended up like this, he just is asking for our help....

Snowjoker, glad you got it started!

Whatever you do, don't call it a Cummings!!

Just a heads up!

 

Sixslug, I don't think anyone is insulting but suggestions have been made and he is ignoring them and continuing on with the same thing he was doing when he started here. So why ask? You do not run WMO in a Cummins, they do not like it. If money is the problem you would be dollars ahead to go out and buy a beater gas pick up and save until you could afford to fix this one up right and run clean fuel in it. If you want to ask questions and then ignore the answers then don't ask the questions. It is just wasting your time and our time. I am sorry if I insulted you. I will offer no more suggestions to be ignored.

I have read numerous threads of guys filtering and running WMO... guess we all are a bunch of dum dums.... My first gen has been running it for the last 5 years.. not straight but blended in various ratios... and i can tell you it does run better because it raises the cetane points, takes the clatter out of the engine...and noticeable power increase.. To each their own, BUT if you have not tried it don't recommend not doing IT !

 

Thought your responses were civil rickf.

As for alternative fuels, there is a few guys around my area running them in their 24 valves with success.

 

I have been a certified master technician for probably more years than some of you have been alive. You are right on one count, I do not run it in my truck. That is because I have had to repair far too many vehicles that have been damaged by it. If you have been running WMO in your other truck for 5 years take a look at the bottom of the fuel tank. I will bet you will find a layer of sludge there. That is the heavy metals and solids that fall out of suspension when mixed with diesel fuel. Not all of it falls out and a lot of it is small enough to pas a filter. I will be the first to admit that I do not know it all but 42 years as a mechanic taught me a lot. I am retired now an still learning. I ask questions on here and I listen to the answers. I take the advice of those who know what I do not. I was not trying to insult you, call you names or tell you how to work on your truck. I was only answering your questions.
