I would think the carb cleaner and ether I sprayed in there would have been enough for it to run for at least a few seconds if it was getting a spark. I might have to bribe some people with beer to help me get it up on the ramps to change the filter.

I haven't tested anything spark related yet besides the ignition switch. It seems to go straight to the DME and nothing I can think of can disable all the plug without throwing a fault other than something inside the DME. The DME is initializing but not reporting any problems.

Loren over at the Renntech forums suggested a large vacuum leak. Anyone have any information about this? I haven't mess with vacuum systems much.

Replaced the fuel filter and cleaned the throttle and idle throttle valves. I tested both and they seem to be working.

So, a final update on this problem...

Bad gas after all. Very odd, but dumping the tank and flushing the lines with fresh gas fixed it. Car started right up and idled right away. It's popped and idled rough a few times getting the rest of the crap out, but after a good drive down the highway everything seems to be working again. I got everything put back together, now I just need to get the electronics sorted back out.

What an arduous journey, glad you solved the problem, what a ******************** this one was. Go for a long drive with the top down.

I'm glad you found it. I wonder what was in that gas. Have you tried it in a lawn mower or something easy to drain?

Got on this thread late...if I just filled my car with gas and started having problems like you described, I would have dump the gas first thing, no ends or butts. That was a positive give away. Cars running fine, stop and buy gas and now I am having problems. The first thought you had was right. Bad gas.
