- My son and I try to get my 1990 F-350 to run. I recently purchased this truck. See my previous videos on this truck:
• Project or Parts Truck... (Project or Parts truck)
• Will It Run 1990 F-350... (Part 1 Steering Column) - Авто та транспорт
I own a 7.3 idi, love it
I'm gathering parts and waiting for the weather to warm up a bit, then I'll get back on this. Looking forward to getting it going! Thanks for watching and commenting!
Use a vacuum pump and a tire filler to vacuum the diesel up to the filter works every time
If you do not get fuel coming out and too the injector you will never get it to run...You have to have fuel going to injectors... Test, remove all injectors nuts so they will leak... Again remove start solenoid and manually slide the direction of coil pulling or pushing... You should get fuel from filter to pump and then from the pump to the injector... Just because coil pulled in does not mean it open the fuel port... Your are going to lose fuel, but it will not start because you have the injector disconnected... Two man job,
Would like to see part 3!
Will be doing more videos on this truck! Keep watching and you will see it run and drive! Again Thanks for watching!
When you guys changed the filter you should of filled the filter up with fresh diesel to pre prime it.
I was afraid to get dirt on the wrong side of the filter. Thanks for Watching!
Exate oui
Prime not pre prime
@@robdoescarstuff4392fill thru the small holes
For what it’s worth… air intrusion… fix that( usually the fuel heater) then crack injector lines one at a time until you get fuel at injector( can take a while)… then it will fire. Drill tap plug the fuel heater is the fix.
It does look n sound like a healthy engine just needs glow plugs
I adopted 1 it sat up for 4 or 5 years . The problem I came across with mine is rain water some how filled the intake complete up didn't realize it till after I put 2 new batteries in it and turned it over 😳 it clunt? I got all the water out and at a loss bout it 4 now. wood love 2 see yall get yours running Caz mines dewin what yours is dew I appreciate the video
That's a bummer, thanks for watching!
I would have to try to pull start that one for a bit, if it's a standard, just to hear/see/ know that the engine will still turn over...before the rings rust to the cylinder walls...hopefully.😮
YOU GET THIS GOING? One thing comes to mind... injectors need pressure ton"pop" open. How are y'all building pressure with those injector lines open? Having them full of diesel doesn't do anything for you unless it's under enough pressure to pop the injectors.
We did not but we have worked on it more. Will post a video when we get it going. Having a shop built this fall and will post more videos after I have a place to work.
So I was having this same issue. I couldn't figure it out. Two fresh big batteries and I sprayed it with starting fluid (I know it's not recommended but I only spent $600 and figured worse case it didn't run anyway) and it finally started after a lot of turning over.
Been trying to figure out why the new fuel shutoff solenoid int working. It passes the check when its off the cover, but something doesnt work when its all together
have the same issue on my f350 7.3 idi.. been sitting for 4 years now .. and now i need a truck.
Use a vacuum pump to pull feul upto the filter till its plumb full using a tire air chuck and hand vacuum pump
didnt c u check if check valve was clogged at on top shut off silinoid.just thowing it out there hope it helps.im going threw same ordeal it sucks
Needs glow plugs to heat the fuel in order for it to fire. Also gotta give it time to heat so you should have a wait to start light come on in the cab. When it goes out you then can crank it.
Previous Owner had been troubleshooting no fuel at the injector. Told me he thought it was the lift pump, so we went down that route but turns out my lift pump was fine. Looks like the injector pump is not pumping fuel out any of the lines to the injectors. Getting parts now, and will continue when the weather gets a bit nicer. Thanks for watching!
@@robdoescarstuff4392 if your not getting fuel to the injectors make sure your fuel shut of solenoid is working before replacing the injection pump
Fuel solenoid appears to be working. I have another pump that came off A running truck I'm going to swap out and will video but work has been crazy lately. Thanks for watching.
I am currently having the same problem just replace the injection pump truck fired right up as soon as I get under acceleration dies no start after and no fuel coming out of injection pump at injectors
I have got a stubborn one to take fuel by running it on starting fluid... its not going to hurt that engine for doing so... you could literally run cans of starting fluid through those old IDI engines and they love it. Keep it running a bit on starting fluid and just see if your diesel does finally make it to the injectors.. I do have over forty years on these old fords
We ran more starting fluid through it off camera and it would fire a bit. I didn't want to use too much though as I'm new to diesels. I'm confident it has compression so I'm gathering some parts and will post another video soon hopefully. Thanks for the tip and thanks for watching!
Having the same issue I narrowed it down to the IP. Not enough pressure to pop the injectors
Ether will tell u real quick what the engine will or won't do
Did you ever get the 1994 running?
Not yet, been super busy with work this year. Thanks!
I went thru 3 mechanical pumps before I switched over to electric lift pumps.
Most likely you bought a aftermarket name brand or cheap one. I did the same thing nothing but junk! I bought a Motorcraft one and running 3 years strong! The electric pump is nice but the mechanical pumps are more dependable
@@jackdaicole7595 I'll never go back to a mechanical pump. I have an extra electric pump in the glove box. Haven't had to use it.
@@2ndspingarage well to each thier own I guess lol. The mechanical vs electronic both have thier pros and cons
@@jackdaicole7595 priming the fuel is a breeze.
@@2ndspingarage have you had any issues with priming with mechanical pump??? I would fill the fuel filter up and hold the vavle open and tap over the starter from I side the engine bay.
Take the high pressure pump off and clean and blow it out good, then hook the pump ,then turn the pump somehow [ drill or 110 motor with an old belt] and pump fuel in the pump with a hose and a upside-down bottle to feed it. As it turns you should see fuel coming from the back of the pump ware the injector line hook to it. If not the pump is not working. Get the high pressure pump to work and get fuel to the injector it should run. If I remember correctly the injector work off of oil pressure to open the injectors.
Thanks for the tip, I was trying to figure out how to test the pump, spinning with a drill is a good idea. One of the injector lines is cross threaded at the injector from the PO working on it. I picked up a used pump and lines this past weekend off a truck that ran but was overheating. Hopefully I can save the injector. I'll test it like you said and install it. That will probably be my next video so hopefully I can get to that in the next couple weeks. The weather is bad right now. Hoping I don't need injectors too. Thanks for watching!
It has mechanical injectors, heuis we’re introduced in 1994 the oil pump does not create pressure. It creates a volume of oil for the injectors to use. The injection pressure regulator (controlled by the PCM) is responsible for creating injection pressures in a range of 450 to 3,000 psi on the Heui injectors, the 7.3 power stroke is computer controlled and the 7.3 idi is mechanically controlled the 7.3 powerstroke is also direct injection and 7.3 is idi (indirect injection) witch means it will go into a pre chamber then into the combustion chamber
