Check your coil. A lot times you replace a part and the part goes bad because of another malfunctioning part. The spark can look good, but under load Its not enough. Problem is in the ignition somewhere.
#105 of 108 van won;t crank

we bought an 03, 3500 express 6.0 yesterday and drove it home. today it won't crank. when i first started trying to start it, the gauges would do a little dance and then register, then the needles would do a little dance and not register and the radio quit coming on. when i turn the key i can hear the fuel pump working but the starter doesn't click or nothing. we changed the batt, checked the fusses and ohm'd the relay. any ideas ?
#106 of 108 96 g10 stalling and starting problems

Ok so as many of you I have had all the same problems. I had poor gas mileage, random stalling, starting problems and also missing at highway speed without a load or under heavey throttle. I noticed my timing was all over the place and the cap and rotor button where in bad shape. I changed the ditributor (a bad rotor button and cap may cause missing but play in the distributor shaft will cause the timing to bounce all over) and put a new cap and button on it. This solved my timing issue and missing at highway speed. I figured perhaps it was the distributor. for the next 2 days everything was great, no stalling and fuel mileage was way better. Then the family and I went to the store and out to breakfast. It was really windy and was blowing the van all over the place. while at speed the van stalled again and as many of you, all componets inside the van powered down. The needles on the guages did a little dance and then everything went back to normal. I drove the rest of the way home and parked the van.
The next morning I went to leave for work and once I turned the key all the lights turned off and I had nothing. No clicks at the starter or anything sign of life at all. I did some research as I was starting to think I had a coputer problem. As it turns out 1996-1998 GM made the housing of the computer out of aluminum and the bolts that hold it together out of steel. What happens is that the steel bolt heads corrode and break off, the heads of the bolts are on the bottum and when the break they allow moisture to enter the computer. If you look under the master cylider you can see how this could be a bad choice to locate the computer and also how rain could sling onto the exact location of the connectors and front bolts.
So after reading this information and also watching a video, I removed my computer and inspected it. As it turns out I was not impacted by this problem but did see corrotion all over the computer and decided to mitigate the risk by replacing the bolts with stainless hardware and also using rtv to seal the two halves of the computer case.
Then I sat down and documented all of my problems and what I was doing once the van stalled and something I found in common, each time it was very windy or I was turning the van to the left. I had allready checked all grounds etc and the battery was only 6 months old so I didnt bother with that. Well that was my mistake. The battery hold down was not tight and when turning left the battery was sliding and pulling on the cables. Even though they seamed tight enough I disconnected the battery and cleaned all connection points then reinstalled it and tightened the hold down snug to insure the battery does not move. Needless to say all my problems are resolved.
I hope that you get as lucky as I did but if it wasnt that simple I also hope I helped by informing you about the computer problem they are known to have....

I would also like to add that before changing the distributor I had the random high idle issue others have had as well. If you have a nice scanner you can graph the timing at idle and I would jump between -2.7 and -27.5 degrees at 654rpm. after changing the distributor the timing looks like a flat line and the engine idles proper.

i would like to add what we found. we bought the van and drove it home no problem. the next day i went to start it and nothing. DH got under and jumped it with a screw driver while i turned the key and we got it started. we went and got a new starter and DH informed me that we might of saved that cost if he had made sure the wire connections on the starter were tight in the first place.
