I started a thread on 03/28/2011 with the above title of SMOKE/ SIZZLING. Yesterday I reported back that the car started right up after changing all the GP and I ran it for about five minutes driving around the block. Today my wife went to use it, it started immediately ran rough then died and now it cranks but, does not start. I did not remove any fuel lines or do any other maintenance to the car. Any ideas anyone????

Replaced my glow plugs as previously mentioned in other threads . I noticed an electrical plug square 2 hole with a wire clip on it hanging between the intake manifold. This same wire/ clip combination is attached to the CROSSOVER PIPE on a vacuum fitting at the OPPOSITE side from the air filter. These two wires are identical so I am not sure if I mixed them up. I have removed the crossover pipe again but, cant seem to find where the second wire would go without taking off the intake manifold again. Can anyone tell me where the second wire goes??. I already know one goes to that vacuum but, where does the other go. Looking at the wires one is brown/purple the other brown/blue. the numbers (pa66-of )are on both of them and the both have the numbers 1-2 on both as well. HELP HELP

There is an electrical connection at the flapper on the crossover pipe, and an identical electrical connection at the flapper on the intake manifold. You should be able to connect the manifold connector without removing the manifold, but it's reaching around blind.

Both flappers also have the vacuum connections as well.

Mark, thanks you were 'dead on'... found it immediately groping around that is the one one the intake. Jacked the car up to get to it from the bottom, was a lot easier. I presume it doesnt matter which is which so I just plugged them both in. The car hard started but, soon smoothed out and began running.
