ignoring the "wait to start" light

[RodeoRob]

being new to diesels, i'm curious if someone could give me a quick answer as to what the ill effects of ignoring the wait to start light?

I know, its for letting the glow plugs warm up, but i assumed if you didn't wait and the glow plugs weren't warm enough, the engine just wouldn't fire. however, i witnessed a few of my friends, out of habit, just sit down and turn the key (cold engine), and the diesel fired right up. Does this produce any damaging effects? if it was the winter time, i would suppose it might not start?

It potentially will smoke a bit more when starting and could run a bit rough. I've never seen that happen yet with mine. I usually spend that time buckling up so I don't notice the wait that bad.

mine won't start... 2-3 tries of long crank's and it'll finally hit, and when tit does, it usually start's on 4-5 cyl's and slowly picks up to 7 1/2 it's worth waiting the 30 or so seconds for the light to go out...

DSI, I forget what year is your PSD? I'm wondering if I just don't notice it's running on less or there's some difference. Mine seems to runs ok even if I don't wait.

Mine's a 2001 and it seems to run ok even without waiting . But i haven't had it very long and haven't done this many times to take much notice.

Yeah that 6 second wait is terrible. At least I can sit in the back seat without my knees hitting the dashboard.

I wait on mine when it's the first start of the morning or if it's cold outside. If I'm running around town making various stops I don't wait.

mine's an 02, it's just a moody SOB! now that the temp's are up in the 70-80 range here 15 seconds is all it needs to start and run on 7.5 cyl's but when it was freezing out, even after waiting a minuite, it would still chuff/smoke/knock/miss been like this since day 1

the glow plug relay stay's hot for 2min so even after the light goes out they're still heating the cyl's

all 8 plug's work, the truck's just a moody SOB, but it sure run's sweet once it's warmed up

And how many thousands of dollars do you have wrapped up in the motor?

I don't think I'm going to go as far as you did with yours. As long as the puter chip doesn't decide to be a pita when I "upgrade" it, I'll be happy.

How many more ponies do you get out of yours?

on my dodge i never wait for the light to go out unless it is 60 degrees or cooler. it doesn't activate the grid heater unless it is 59 deg. or cooler. fords prefere to use the heaters, and older chevys really need them.

well the last time it was dyno'd, with just a 4in exhaust K&N drop in filter, and chip it laid out 303/647 and that's on 315/75's

with the new intake, LL8 injector removed, and the re-plumbed fule rail, we're guessing 320/725 minimum


should know in a few weeks


BTW scott... the chip was $250 used and the exhaust kit is $475, the filter was $35. so what's that... $760? not to bad

the new fuel line is only $20 at a hose shop and theinjector i'm pretty sure i can get a warrently replacement, otherwise it's $195

Well, then I guess I'll know where about I'll end up. I'm going with a 80 HP chip reprogram and a 4" exhaust from SummitRacing.

What about that "new" intake?

i'm re-using the rubber crinkle hose from the lid of the air box to the turbo, i've capped off the crank case vent though, so it will stop sucking 2-3 qt's of oil out of the motor ever oilchange!!!

all i did was get a pice of tube 6 inches long that was the right diameter, and ordered a filter that had that size outlet, and am just making a simple tri-pod style stand to support it.

cheap, simple, garage fab


BTW, i got the new chip today... it wasn't able to be done quite as hot as we hoped... but it should still be resonable for towing for a while. both chip's i have are going up for sale after the first of the month and i'm going to buy a flip chip so i can have the exact level's i want...

On the PSD, the Wait light is controlled by the computer, so from what I understand if has a built in delay to it so you are actually waiting longer then you really have to..

I know mine goes out alot faster during hot days. like I turn the key on and with in 2 seconds its off if I have ran it at all..
