I'm having an intermittent crank-no start on my truck. This seemed to develop over time when the truck would crank slowly almost as if the battery was dead. One evening the truck died for good and couldn't be jumped so in went a new battery. This did not solve the problem. A few days later the...
Just stumbling on this thread because I'm having the same problem with a very intermittent Crank/No Start. Only thing is just about every component in the ignition/timing apparatus has been replaced. It does exhibit sputtering and even some smoke as though it's trying to run but almost as though...
Fresh rebuilt NP246. After switching to 4Hi and hearing a ping or pop from the case, it is 'stuck' in 4Hi an will not return to 2WD or 4Lo. New switch was installed along with new encoder motor at the time of install. Usually ran it in 4Hi for a little bit every week to move things around - but...
Hey guys. Solved this one. Looks like it was a blown ENG-I fuse. Consulted the manual and wiring schematic led me to the fuse box under the hood. Sure enough it was popped. Replaced and everything is back to normal.
Hey guys about a week ago I got the truck stuck pretty deep in mud. After being pulled out and getting back home, the truck has started to do some weird things and have new issues.
1. P0102 MAF Voltage/Signal Low - Upon datalogging, it seems that the PCM is reading no output from the MAF. The...
Just a quick update. This seems to have been fixed with a new thermostat. Operating temps were very low and preventing the truck from fully warming up.
I drove the truck today around town and tried to produce various effects at load while monitoring fuel trims. At 75mph/2400-2500 rpm sustained, the stft was great (1-3%). Ltft was not so great however (12-18%). That said I had zero misfires while sustaining speed and only inducing light load to...
Hey guys, I am trying to troubleshoot an apparent misfire on cylinder #5 on my 99 2 door Tahoe. The problem only occurs under load, and after the truck has warmed up. It has had the newer style MPI spider installed for almost 5 years now, and the shop near me thinks it's a bad injector. My...
So I located the culprit. Seems somewhere along the lines of removing the old case or whatever - the jackets on both the wires on the drivers side VSS were frayed. Did some heat shrink and re seated the pins in the plug and all was good after that.
Hey guys, just finally getting my truck back out on the road yesterday when it definitely was having a major problem. The transmission was acting very bizarrely - shifting only into 2nd and downshifting back into first on application of throttle. In addition to this, the transfer case fuse blew...
So this has been resolved. The truck did, in fact have the CA emissions. A proper midpipe was installed. Me and my dad made an adapter harness to run the O2 sensor on the drivers side over to the pass. side.
As a further note... The Magnaflow 23453 midpipe will require slight clearancing of a...
Hey guys I am looking at the diagram and it seems that some how my truck has a completely different exhaust setup. For one, my midpipe has the cats flanking the transmission on either side. This agrees with the plug for the drivers side aft O2 sensor as it connects at that location. For seconds...
