yet one more question on glow plugs, need some fast help

[84cucv1ton]

finally sold the k5. he bought a new relay, plugs and batteries. even gave me some cash to put them in. it started ok before was not that great but it did start. now 2 new batteries, plugs and a relay. will not start at all!! its 40 something outside too. i checked everything before i turned the key. cranks good and fast. i know its getting fuel. put the new plugs in with anti seize all over the threads, like i was always told to do.


hes going to be here at 6 to get it and i cant get it to fire. im really scraching my head on this one.

any ideas?? any help would be great thanks mike

What is the part/model number of the glow plugs themselves?

//on the off chance you have the wrong ones


edit - Also, how long are the plugs cycling when you start it up and can you confirm that you hear the gp relay on the firewall clicking?

if you haven't already, I'd suggest getting a digital camera and snapping a few under hood shots of anything you have touched as you may find you nudged something and one of the more savvy folks here may pick up on it.

I know that it is bad, but did you try starting fluid?

 

[84cucv1ton]

plugs are wellman 070. the wait light is on for about 7-8 seconds. relay is clicking. i can take some pics.

not sure if its true but was told starting fluid could blow the head gasket. never used it.

Pull the glow plug card out so that the plugs don't come on, spray some starting fluid in the intake and then see if it fires. If it does, you are more likely to have a fuel issue than a glow plug issue.

The warnings about not using starting fluid are due to the automatic glow plugs. I guess it's easier to put on a sticker about how to never use starting fluid than a sticker about how to pull the card to disable the plugs.

very sure im getting fuel. smoke out the back is a sign of fuel. right?

 

[hobie237]

Generally yes.

Have you confirmed you are getting voltage to the relay and that the voltage passed through the relay when the key is turned on?

Have you pulled a couple of glow plug wires off and confirmed that they are still good? Easiest way is to pull the wire off and check for resistance.

 

[mangus580]

Wait light is not on anywhere near long enough... that is a good indication the plugs are toasty fried.

 

[84cucv1ton]

really?? plugs are not even 5 days old. michael, relay is good. power is going to the plugs. whats should the resistance be anyway? i was getting 12v but i could double check the resistance.

thanks

What is long enough for glow plugs?

btw, when was the last time this thing was cranked?

 

[84cucv1ton]

to think of it plugs should be on for about 12 seconds right? could you tell me a bit about that? i have no clue how they could be cooked?

 

[Michael]

They usually fail open but can fail to a dead short anything in between is good,.

 

[84cucv1ton]

mangus580, right on cooked plugs. 1 stuck, 3 swollen, one has a melted end. now i need to figure out what caused it.

Interesting, Wellman 070 glow plugs are not supposed to swell.

 

[hobie237]

Three of mine did. Everybody says they don't swell, but everybody also reports that they do, in fact, swell. That said, none of mine were bad enough that they gave me any trouble coming out.

 

[AJMBLAZER]

Huh, wow. I had a bunch of dead Wellman 070's in mine last year. Crap covered and definitely dead but none had swelled. Guess I got lucky.

 

[mistaken1]

So are there any glowplugs out there that are better than the Wellman 070s?

Did this truck ever get started?
