I doubt the chain jumped. If it did, the timing could be way way way off and it could have valves opening as pistons are coming up. IF the chain jumped it could be far worse than just slapping on a new chain.
How did he diagnose a jumped chain?

 

^^How did he find out the timing chain? I wouldn't go off his word - don't trust anybody. Either look at it yourself or take it to a shop that you know (dealership) and make sure it is something as simple as the chain.

That said, here's a DIY.

A superchips tuner would be effective if you can input what kind of thermostat you have installed. I am not sure that it would have that feature though.

However, I do know that some people on here have a 180* thermostat in the summertime, and switch back to the 195* in the winter. But then you have to keep switching back and forth between thermostats.

Remember though, that a cooler engine might be recieving cooler, more dense air; but an engine running at operating temperature burns fuel more efficiently.

 

Once I pick er up saturday morning I will.

He said he did a complete tuneup, etc great for about 2-3 weeks. Then it was starting to run rough and now it just won't run at all.

Could be a shotty tuneup also. New IAC, MAP, and TPS

Had dist cap, rotor, pickup coil, wires, plugs and a new fuel pump

 

I live in texas and we get the 100+ heat here in the summer time so im assuming all it can do is help.

 

100 plus is a lot different than 20, you want it warmer for the heat .

Going to check it out tomorrow and throw a deposit down, won't be getting it towed up here till Tuesday or Wednesday and i'll start deassembly/diagnosis next week (Late work week this week)

 

So it's arrest me red. 134k it's in decent shape so I'lklupdate you guys this week once I nab it.

 

I dunno It pretty cold here in Buffalo and my 180 stat still lets the truck get plenty hot enough for the heat....were talkin 15 degrees here ...I could see the 160 stat having issues...but I get no cel.

that also seem kinda weird that it just quit running like that have you tested the fuel pressure or checked for wet plugs? also I would think you would get a code or two at least?

 

Getting it towed here Tuesday, gonna report then. Will check for CEL's and stuff then. For $700 can't complain.

 

When I had a 180 stat, my temperature wouldn't get above 160. And that was in 60 degree weather.

When your engine is below operating temperature, it doesn't care about the air/fuel mixture, cause as far as the computer is concerned, the engine isn't hot enough; so it runs rich. Once it gets up to the temp the computer wants (it won't usually with a 180 stat), then it will pay attention to the oxygen sensors and adjust the air/fuel mixture accordingly.
