7.3 Powerstroke Archoil cold start. Will it start?

A series of tests of cold starting the 7.3 plugged in, not plugged in, and not plugged in with Archoil ar9100

[@marm842]

I have 02 7.3 rotela 15/40 rear round .no additives .no plug in .358000 miles never been touched. Had to prove to friend .no plug in temp was -38 it sets out side.3 time engine turned over veroom an he's alive.

I like the radio station 👍

[@jimmotormedic]

Why does everyone cycle the key like that? When you turn the key on with a cold engine the glow plugs stay on up to two minutes after the light goes out. Complete waste of time. When it's 0 or below I wait up to 30 seconds after the light goes out and start it up. Never failed me yet. If you don't believe it watch your volt gauge on a cold start, it will be in the basement until the glow plugs shut off. 5w-40 is the only oil to use in this engine especially in the cold. I also don't drive away until the high pressure pump stops whining. That's another clue of thick oil and lack of lubercation. 7.3s are great engines

[@stitchthisditchthat259]

Most people think the light goes off and yer good to let er rip lol

[@psd28]

@@stitchthisditchthat259 once the light goes off you are in fact good but they do keep running a while if its cold to help it run smooth

[@lenluksa326]

As 1DirtyMutt stated, the WTS light does not indicate when your Glow Plug Relay is activated. It is more of an "idiot" light ... like the oil pressure gauge on your dash (it reads either yes or no to oil pressure). If you watch your voltmeter when you first turn your key to the KOEO position, you'll notice the voltmeter reading drops as the GPR energizes the Glow Plugs. This cycle can last as long as 2 minutes depending on the outside ambient temperature. The colder it is ... the longer the GPR will stay on energizing the GPs. Also, you are cutting your crank cycle WAY too short. Try cranking for between 6-10 seconds. (yup the manual states up to 30 seconds before you harm the starter). 6-10 seconds will not hurt your starter and chances are, it'll fire up much earlier. By you turning the key on and off quickly, you are simply terminating and resetting the GP warming cycle unnecessarily. BTW - Archoil does work well when you follow the instruction properly.

[@mudracer007]

you didn't let the truck spin over long enough you cut the key off to quick

[@retiredfire2013]

Learn how to crank a diesel in cold cold weather PLEASE !!!

[@1DirtyMutt]

Your WAIT TO START light has NOTHING to do with your GPR …NOTHING! Wire an LED Light to your GPR and then you’ll KNOW how long your GPR energizes. Read your manual, that information is actually in writing.

[@colekitten1367]

1DirtyMutt same he let’s go too quick

[@23srry]

Try actually letting it crank over. Trying to start it like it’s warmed up is going to take you forever to start it no matter what Diesel engine it is. Once it start’s hitting don’t let off

[@arloowens4292]

I noticed your fuel level is at a quarter tank. In the owners manual it says not to let it drop below 1/2 tank especially in cold weather

[@MrBellyman128]

Really? Why?

[@BrigT262]

last set of glow plugs I did were on a 97 7.3L in dead of winter. I was amazed at the difference new plugs . I'd try a new OE relay & plugs.

[@ericsscout]

That's the plan this summer. All new glow plug system.

[@supremeautomotive6749]

Just do relay first

[@dirtyminerapparel]

I love Archoil. Got that tip from Bill at PowerStrokeHelp. I run a cap of it in my power steering as well.

[@mr.s7059]

Time for new glow plugs and a glow plug module there's 75% of the battle, and run the correct oil weight for the temps.

[@blakeportelance100]

Any diesel at the cold temperatures would have a hard time starting so running the glow plugs the way you did was good for ignition. When it started a smoothly as it did "no misfires" means the archoil helped with stiction issues. I put archoil 9100 in the freezer and it turned into molasses... not against the product but anything up north in cold weather it doesn't matter.

[@samuelbirdsong7371]

Crank it. My 7.3 takes longer to crank and im in florida. I have stiction bad next oil change im putting archoil.

[@MrLegoman2472]

I have a 2001 7.3 and the manual says you can crank your truck for 20 seconds with out doing damage to the starter so I crank longer and have no problem starting with out a block heater in the cold. P.s I live in Canada so it's cold

[@ericsscout]

That's good to hear. I had a bad experience with an older chevy diesel cranking for periods of time like that. Cost me a starter and new battery cables.

[@MrLegoman2472]

Eric's Projects fair enough you do you

[@ericsscout]

***** I have just received my new glow plugs, oem Ford ones and those will be going in soon. Thus summer I will replace the wiring harness under the valve cover along with the relay so it's all new and gives me a solid baseline.

[@taneesescu]

@@ericsscout how did redoing your harness and glow plugs go? Did the harness improve anything? just wondering if you were getting DTC's or had any grounding out, upgrades to your wiring in the dash? Just wondering

[@buckhorncortez]

Having owned 7 Ford diesels, starting with a 1988 IDI - you don't know how to start a diesel truck. I have started Ford diesels in temperatures down to -14 F without the block heater, and NEVER had to try more than two (2) starting cycles. You have to CRANK the engine to build pressure in the injectors and preheat the cylinders. Crank the damn thing for at least 20 seconds on the first starting cycle. It should start on the second try if you do that.

[@awdgeorge3872]

Mine on my first crank it takes about 5-10 seconds

[@buzzsaw301]

actually you can access the other 3 qts, you have a hpop plug on the top of the reservoir that takes an allen wrench. you have to vacuum pump out 1 qt at a time. I would throw half of that archoil bottle in there.

[@ericsscout]

buzzsaw301 thanks for the tip

[@Richard5873]

So it holds 3 quarts? I did not think it held that much.

[@RoadKen53]

Your glow plug relay keeps working after the light goes out up to 1 minute or more.You need to learn how to cold start it by letting it crank more.

[@partssman1]

Powerstroke help .com has a KZbin video on getting oil out of HPOP

[@downhilldaddy9346]

well I took the archoil additive to be like a slick 50 kind of additive. not a block heater or glow plugs

[@ericsscout]

Exactly

[@downhilldaddy9346]

It does help the injectors tho

too much dramma here use the 6200 & 9100 you will have a smooth running truck ,,,, my car my motorcycle & lawn mower & girlfriends car all use arch oil & they are SMOOTH !!!!!!! N O JOKE

[@ifronnin]

Even with Archoil it needs cranking time to build up to 500psi of injection pressure. Add cold oil to the equation and negative temps you'll need about 5 seconds of cranking before it'll even begin to actuate the injectors. 6 Minutes of glow plugs probably just heated the oil in the galleries and thus allowed it to fire with less crank time. Your truck though, treat it as you discern best.

[@rjpowerstroke6368]

Put your glow plugs on a switch!! Very easy to do.

[@fordnut4914]

I got a 95 stroker that starts in the coldest temperatures 300k miles on it starts quicker than my neighbor cummins.

[@jeffquinn5653]

Think your barking up the wrong tree. Generally, if the injectors, glow plugs, relay and batteries are in good shape should fire up.

[@jameslundy70]

It is a damn FORD what do you expect.

[@steverivinius5686]

Yep.and you know when it's warmed up because you won't hear the power steering pump.

[@gannonfamily2000]

Your glow plugs will heat for 2 min when they are turned on. Constantly cycling the key and trying to start at very cold temps just wears out they ignition switch and takes longer to finally heat the cylinders Chambers. If you are having problems in those temps after a minute or so after the start light shuts off, Then you would probably have a glow plug system failure. Plug it though. You won't beat the hell out of you injectors as much as a cold start can. Archoil will also save you a ton of money by extending the life of you injectors and all other friction parts in your diesel engine. I'll have to try some off that oil slickening compound next. I get impatient and usually wait for one minute at those temps and mine fire right up. I used Revx with same result as Archoil and am now trying out Turbo Maxx with more friction reducer additive. It seems the same though it works good and should be protecting and stabilizing the oil a bit longer.

[@psd28]

this dude has NO IDEA how to properly own a diesel or operate it.

[@packingbone1953]

Do you still have the 7.3’s?

[@mrhaggin429]

You need to test your glow plug relay. I live about 4 hours west of you and never plug in my truck at work. I usually let the glow plugs run for 45 seconds or so and my 7.3 fires right up.

[@howardwatts4238]

according to u tube u have the same barring failer with 9100 as without do the reaearch

[@jeffersonmoctezuma3733]

You have to let it crank over moree cause it will take foreever to start

Oil and oil additives will not make you engine any easier to start unless they’re being fired into the combustion chamber.

[@chickenknucklez2604]

[@johnyq9105]

[@ericsscout]

johnyq I've since changed out all my glow plugs for new Motorcraft ones, new heavy duty relay, and new valve cover gaskets with wiring harness. Still having starting issues and will be putting in new injectors soon. It's having all kinds of no start issues unless it's plugged in.

[@supremeautomotive6749]

Use 5w 30 not 10 or 15

[@blackhatter011]

I think it's the driver that's the problem.

[@84400]

do you need to cycle the key so much? on my diesels the wait to start will go out but the relay is still on for a good while after unless the key is turned. i do run self limiting glows to avoid swelling. this is on a gm6.2 and mercedes benz om617. i much prefer the grid heaters on my 12valve cummins. seems to always start better in the cold.

[@ericsscout]

Everything I have ever seen or been told is yes you have to cycle the key so it resets. It won't just keep heating up. I am at 234000 miles on the truck and the plan is to replace all the glow plug items this summer. Relay, glow plugs, injectors, and wiring harness. That way I know I am as good as it can get.

[@AgTires4295]

Eric's Projects The PCM determins if the plugs are activated (obviously in your conditions they are) and for how long. Even though the light only lasts seconds on the dash, the glow plugs are activated for upwards of two minutes. There's no need to cycle. You can install an LED anywhere in the truck to monitor the relay's activation/deactivation (or monitor voltage).

[@dross8580]

AgTires4295 exactly the relay stays on for about 1:30 after the light goes off you can test it by putting a test light on the ground and putting the probe on the back relay and have someone turn the truck on

after having five powerstrokes I finally got rid of all their b******* in 05. I bought a Dodge with a Cummins in it 4x4 I have yet to have this truck fail on me yet. it's a one ton and it gets used hauling 20,000 plus pounds regularly. the power strokes never made it to a hundred thousand miles without serious and expensive damn injector work, EGR, oil cooler. and the list goes on and on. so far after 12 years with the Cummings I have replaced a water pump and a serpentine belt is all I've replaced other than batteries Brakes and Tires. I'm also a mechanic so I've never taking my truck to a Dodge dealer but once and that was enough. I guess I can drive it for another 10 or 12 years before I have any real problems. good luck with that Ford you're going to need it
