I was traveling home one night when all of a sudden my truck started sputtering slight backfiring then shut off. I waited a short bit of time and it was hard to start but it did start idles really rough then sputtered again and died. Could not get it going had to leave it had a mechanic come and look at it and said he thought I needed the Electronic Module and a distributor cap, rotor, plugs and wires. Installed all of that and made no change. It did start it was very hard to start and I limped it home. It was acting like it was not getting fuel so another mechanic misread the fuel pressure specs and thought I needed a fuel pump. So I put in a fuel pump filter and fuel pump relay made no change. Tried to get it home it kept dying we started a couple of times I could drive about a mile and it would die. Until it finally would not start had to leave it again on the side of the road and towed it home the next day. I have had five mechanics look at this truck and only one found this problem online and told me to unplug the alternator and see if it will start. So I can now unplug the alternator the truck will start and run and drive. As soon as I plug the alternator back in the truck immediately dies. I have also replaced at the ECM no change I replace the alternator no change. I am now seventeen days down five mechanics looking at it one of them being a twenty year GM mechanic veteran. All left scratching their heads one of them even saying that the gremlin in my truck is smarter than he is. So seventeen days later I am still broken down. I have now lost my job because I have no transportation and I am very frustrated. I know a fair bit about cars and I have done tons of research over the past couple of weeks. We have taken a test light and a voltmeter and checked every stinking sensor in that truck and they all are functioning normally. The injector is functioning normally I am getting spark I just do not know what to do next. The common denominator is the plug on the back of the alternator two wires one red one Brown one goes to the light in the dash and the other to the ignition. I have read that it could be an ETS problem with the brown wire with a black stripe to be grounded or open or it could be the purple and white wire. I just don't know what to do next I have replaced several things on this truck over $300.00 worth of parts and I get no change. Can anyone please help? There is very little online about this problem. I found one blog or a guy had the same truck as I do had the same problem was communicating with a mechanic asked if he can run a new wire from the plug of the alternator that goes to the ignition in other words just run a new wire from point A to point B and if that would fix it then the blog stop but there was no answer. I am so frustrated I do not know what to do several mechanics $700.00 and I still have no vehicle has anyone heard of this problem and how to fix it.
have the same problem?
