6.2 Diesel is getting hard to start?

Well my girlfriends 1984 Blazer with the 6.2 is getting hard to start. About a week ago after the glow plug light went off you could crank it right up. Well now you have to turn it over for 5-15 second before it will start (this is just a rough guess on the time you have to turn it over),but but if you pump the pedle once or so it will start sooner. Where should I start? I am thinking about buying it from her,but maybe not if it could be serious. Here are the specs:

1984 Chevy K5 Blazer
6.2
700R/NP208
10 Bolt F&R
Factory Rally Wheels W/ 31" tires
67,000 it does not smoke
It was owned by a elderly couple since new

Thanks for your time. [img]/forums/images/graemlins/ears.gif[/img]

I would start with the glow plugs. That is where my problem was from. You will get a lot of good help on here. They helped me put mine back together. Mike

Pumping the pedal doesnt do anything. But you are supposed to hold the pedal down while cranking, half way if above 32 degrees or all the way if below 32 degrees. If it started good before I would check the glow plugs, maybe there not all glowing.

Re: 6.2 Diesel is getting hard to start?

Another test is to hook up a block heater (if you have one) overnight, then try to start it up. If she fires right up or fires up way easier, it's glows.

You can get a whole set for about $80 if you look.

FWIW, you're supposed to hold that gas pedal down according to the manual. I personally hate to do it since it revs up on start and there's hardly any oil in it at that point.

Mine needs glows, but I can start it when I hold the pedal down. Once I let go, tho, it usually dies unless it's quite warm out - until it warms up for about a minute.

Good luck!

Doesn't mean it don't have a block heater. I was in southern AZ and on of my GAS trucks came with one. [img]/forums/images/graemlins/smile.gif[/img]

Did ya happen to replace the battery and starter cables too? My problem started there, especially after they melted off on a cold winter morning!! [img]/forums/images/graemlins/rotfl.gif[/img] [img]/forums/images/graemlins/rotfl.gif[/img]
