97 psd starts and runs ok after warm

i read through some forums and thought i would try some stuff. still having trouble. replaced cam position sensor, and glow plug relay. this morning same old thing. i can hear a sound like a fuel pump under dash on the drivers side only sounds for a few seconds, then the wait to start light comes on, and at the same time you can hear the glow relay click. then the wait light flickers and the relay releases back and forth as the light flickers. yesterday it was warm enough to start up and go to napa to get new relay. after i changed it i turned the key and it waited to start, energized glow relay and started fine several times. this morning back to same old stuff. i know it's not really cold enough to have starting troubles, 70's but i also understand first start on "cold" motor it needs glow plug assistance. i tried to check hpop oil level and stripped out the allen plug am trying to remedy that problem this evening.

This sounds to me like a problem maybe. The fuel pump is what you should be hearing and it should pressure up for more than a couple of seconds...more like 20 seconds.
That is if the 97s operate like my 03....which im assuming it does, maybe I"m wrong.

Your barking up the wrong tree buddy. with an ambiant air temp of 70, the glow plugs shouldnt even be needed.

Is it hard starting?? any smoke?? how long does it have to run before it runs properly?? once it is warm, is there any noticable issues, or is it running like a champ???

I got that same sound under the dash, when one of my batteries took a dump and the truck wouldn't start. I installed new batteries and the problem disappeared

got off work due to rain. just tried to start up and done same thing. this time though i let it go through it's wait to start light fit and clicking the glow plugs off and on. when it finally got tired the wait light went out and the glow relay stayed on after about twenty seconds or more i turned key on over and it fired right up smooth like it always has. marc you say i'm barking up the wrong tree, point me to the right one. i'd like to fix myself if possible, if not, it's a lube job before, and after the diesel shop. to me it runs great after it does the heat up with the glow plugs. if you don't wait till it gets some heat it will start but misses, lopes, belches, aches, burps, coughs, studders, and every now and then it eventually dies.

thanks for the replies

Unless he has put an aftermarket fuel system on, then he has a mechanical fuel pump and shouldn't be hearing anything like that.

no aftermarket fuel stuff like an electric pump. the sound i mentioned was like a fuel pump and sort of like a servo motor. hard to explain sounds on the key board.

what controls the glow plug relay? is there a sensor that controls it or is it driven off of the computer, or both?

I had that buzzing kinda noise under the dash, I haven't heard it since I put the new batteries in.
