Brad,, I think he has an IDI ( 1991) yours is E ( 2001) ..
The injectors are not under the valve cover and can be easily accessed and pretty cheap relative to the HEUI injectors in the powerstroke or 444E.


OP, If it runs good when started, has decent power, does not smoke, runs even, then all is probably OK. So no worry.


Both of my 7.3 IDI's did not like to start at temps below 40F. Just plug the block heater in, better for the engine any how or if this Cali version does not have one get yourself a used webasto tsl17 or similar. It will be useful for heating the rest of the vehicle as well.
No need for Doom. Just read up on your engine and try to get familiar. Never completely rely on a dealer or mechanic. It is a 27 yr old vehicle and any NON DIY repair will quickly cost more $$ then you paid for the vehicle.


Good luck J

I always do fill my own tanks. But at the dealership they drained the tanks to diagnose a sending unit problem. Someone on the floor, thinking they were being helpful, grabbed a gas can and filled them back up again, never stopping to think that it might be diesel.

This problem happens every day. I could overlook the signal turn being on once, maybe, but not on a daily basis, especially when there is no way for me to accidentally leave it on when backing into my driveway. I'd have to turn the signal on manually every time I park for that to be the issue.

You're correct except that "he" is "she." LOL

It does run good, in fact so far I have never had a problem with anything other than the initial start-up. It has been parked for up to 4 hours and I've been able to turn the key and go. Haven't had an opportunity to test it longer than that, and it hasn't gotten below freezing much yet.... so I guess we shall see.

I'm not gonna lie, the odds of me becoming savvy enough to do much DIY are slim, but I obviously have to figure something out or I will be even broker than I am now. Just even knowing the right questions to ask is harder than it seems.

The fact that you get hit with such differing opinions makes it complicated, too: I mean, on this thread we've got one person basically saying "don't idle" and another telling me to idle the entire time I'm off doing my grocery shopping. For someone who just figuring all this out it's hard to find the right path. The only thing I can do is go with what feels right to me. I used to think whoever seemed most confident must be right but I have learned through this whole ordeal that confidence does not equal competence. The folks at the dealership were very confident people.

I haven't had a vehicle newer than 23 years old in the past 20 years. The difference is, this one is diesel, and also, in California I had a mechanic friend who took care of me. Here, it's been pretty much heartache so far.

My last 2 vehicles were 25+ year old Ford Rangers. Barely needed maintenance. One, a friend totaled while he was driving it. The other, I crashed up myself. Otherwise they'd still be running. i call them rubber band cars - if they break, you just replace the rubber band.

a couple things stand out..



1. it starts when its hor so sounds like fuel delivery isnt an issue.. however compression may be.. as well as how fast does it sound like its "spinning" over?


when the engine is cold, it is harder to start so requires it to spin good (esp if its older and worn) to buoild enough heat to kick over..



to make sure the glow plugs are working you need to make sure that they are actually pulling current.. you can say the relay is good, clicks on and all. but put a clamp on meter across the leads coming off of the relay toward the heads and make sure they are pulling current.. if no or very low current pull is observed then something isnt right, bad wire, bad plug, etc.



also check voltage from the out lead of the flow plug relay (big terminal with wires going toward the heads).. thats where you place the positive meter lead.. then place the negative meter lead on the engine head. - clean part of metal.. I say use this as thats the "reference ground" that the engine is using for its ground..



a thought that came to mind as I was driving my bus is that the clicking on and off is the relay pulling in and out repeatedly which would limit greatly the amount of heat created by the glow plugs..



low voltage to the relay or a poor ground, loose connection could be a culprit.. if the voltage varies wildly on the output terminal it means that relay is going in and out constantly which it shouldnt do...


so thinkl of this scenerio



1. turn the key. relay kicks
2. voltage at relay drops due ti poor wiring /. bad ground / bad connection
3. voltage drops below where the relay can stay on.. and it shuts off - Click!
3. coltage instantly raises back up because no current drawing it down. relay goes back on - Click!
4. repeat cycle..

not much heat is made.. engine wont start cold

I had forgotten about that. The relay may click but power not getting thru. Check for power at the gp terminal side with the relay on. If not the relay is bad.

Yes they do cycle and it is the glow plug relay that you hear.

Yes completely normal

Is that an IDI thing? My 444e glow plugs heat continuously and even for a bit after the light goes out, and even for a minute after the engine starts ..
I hadnít heard of them cycling on and off along the way. I do know they all have a timer that shuts them off should you just turn the key and walk away, they reach a max time and just turn off and stay off

I *Think* (and I'm going on memory for this at the moment) they heat for a predetermined amount of time, based on what temperature some sensor says it is. After that, they cycle until (a) the engine is started or (b) the switch is turned off or (c) the system times out.

Sorry about the he/ she assumption....

Brad..yes that is how I understand it. The cycling after the start is helping reduce smoke during a cold start. Once on temperature they have to cycle as not to burn up to quickly.

That's OK... It's kind of a compliment that you didn't figure it out right away, so I guess I don't sound as un-mechanical as I feel. Not that women are not mechanical... but most of us were not really encouraged to develop that side of ourselves so it's like learning an entirely new language. Of course it's not impossible to learn but I'm always trying to figure out how to fit 48 hours of To Do List into the 24 hours in a day as it is. Lots of times, sleep doesn't even make the cut!

I'm old enough that when I was in school girls weren't allowed to take shop class, and I had to do Home Ec instead. However bad I may be at automotive work, I promise I'm worse at sewing so that was a wasted class.

Yeah I had to read thru your previous threads and some of your blog.


Sorry , you did not seem to have to much luck with your bus. All things considered you did well, others in similar situations have abandoned their rigg at no fault.

Shop class or home EC , both are skills that can save you money and make you more independent.


Good luck,

Johan
