hello, I just wanted to update you on the truck. I got my scanner and plugged it in, got no codes. Decided to see if the truck would start and it did, I did nothing to the engine. Once it started It was misfiring alot but it seems like its progressively getting better. Does anyone have any other Ideas what it could be? Also does anyone know of a cheaper way to do a fuel injection cleaning other than bringing it to the dealer? thanks.

I had a similar problem last week. Truck starts fine when cold but hard starting, or won't start at all when at operating temp. Did some research and found some answers at fullsizechevy.com. A lot of the people posting there had the same issues. Found out the hard starting was caused by a leaking fuel pressure reg. On these 98-01 Sequential fuel injection Vortec engines the spider assembly and FPR are located under the upper intake manifold. once the FPR starts leaking, the fuel collects in the intake manifold and sits there flooding the engine. If the truck sits long enough the fuel will evaporate and the engine will fire. The fix for me was to purchase the upgraded Spider assembly for SFI vortecs, instead of just a FPR. This upgrade does away with the poppet style injecters and replaces them with real injecters and is complete including the FPR (GM#93441235) and is a direct bolt-in. From what I gather GM had to develop this because of problems and a recall in CA with the poppet style injectors getting clogged because of the additives in the fuel there. Since I had it installed I noticed the smoother idle, starts with just a touch of the key, and better throttle response. Haven't checked fuel milage yet but should be back to my normal 17-18 mpg city

My truck just started up the other day and is running fine now, it misses every once and a while but I'm thinking it was bad gas. Where can this upgraded spider assembly be purchased? I heard these poppet style injectors are nothing but problems. thanks.

I got mine at a local AC Delco supply store, 1/2 price compared to what any dealership wanted. I heard of other people ordering from gmpartsdirect.com for around $260
#200 of 416 ABS problems

I have a 2000 Sierra 4WD with just over 99000 miles. It has developed a problem with the ABS. At slow speed stops on a dry surface, the ABS kicks on just as the truck comes to a stop. It goes off when I pump the brakes. It doesn't do this on hard stops.

Check for a small stone stuck in one of the pulse rings, throwing the sensor info off for one of the sensors. Also check for for a mechanical reason that one of your wheels is turning slower than the others at slow speeds.

My 2000 Silverado had a recall on the ABS sensors. They did pretty much the same thing. Call a dealer and have them check. While you're at it, have them check for recall service on the tailgate cables as well; I had mine snap while standing on it! The bad part is I received the recall notice at least a month before that happened. at myself
#203 of 416 '01 1500HD Fuel Pump Replacement
Apr 23, 2008 (10:47 am)
My 2001 1500HD with a 6.0 Liter has been getting harder and harder to start to the point of having to floorboard the pedel to get it to crank. The truck has approx 182k miles. After that it would run Ok but a little rough idle. I thought it was my fuel pump and my mechanic confirmed it. I have been reading some issues here where some people were just replacing the "fuel regulator" at a fairly low costs. How hard is it to replace the fuel pump and what is a ball park cost for doing it?
