Hey all I'm Charles. Looks like a lot of great knowledge on this board, I'm happy to be a member. Anyway, I have a slight problem. A little background....95 Avenger 2.0 Auto 162k....I had a problem with the car going into limp mode, so I checked and cleaned the TPS, as well as the input and output speed sensors. Needless to say, the limp mode problem persists, but now I have a larger debacle. The car started and ran fine before I did this, but now no luck. It turns over, I'm getting spark and fuel, ASD engages, and fuel pump is good....and I'm out of ideas. Grateful for any help. Thanks.
Darktengu: It started after I cleaned the TPS (which is what I thought could have been causing the car to go into limp mode, but was not). It did not start after checking the input and output speed sensors. Sorry for the confusion.
Nykon: Here is a link to the picture of the input and output speed sensors...2nd pic down
the speed sensors shouldnt have anything to do with it starting...unless im missing something.
when you were messing with the wires down by the tranny did you happen to disturb some other wire(thinking specificly about the crank position sensor, not exactly sure where they are in relation to each other on our beasts.)
im with DT on this, its unlikey that a whole new situation presented itself when you just happened to work on stuff, but stranger things have happened. its probably something simple. as an example, i changed plugs and wires on a 1973 nova, and it wouldnt start, crank, no start, well i had, while pulling off the coil wire, damaged one of the power supply wires for the coil(don't ask how, i think it had been damaged previously i just killed it the rest of the way), the point is just cause you weren't working on it doesnt mean you didnt break it, from personal experience
Pull the TPS off again and make sure it's on correctly. Make sure everything is lined up properly. If your TPS isn't resting against the tabs properly, your computer is reading it, and making adjustments, which is keeping your engine from starting up.

Mod List. Um WAY too many to fit on here. But the engine can handle about 800HP
DT the TPS is seated properly and getting correct voltage readings as well as resistance changes when the throttle is engaged. Any other ideas? I checked the camshaft and crankshaft position sensors and they are working ok too.
So I found something interesting...when taking the TPS out of the loop (disconnecting it completely), the car will start. However, it bogs down and does not respond to any throttle movement. As stated above, I tested the TPS for correct voltage output and resistance and it checked out, but why would the car fire only when it is disconnected?
you could have resistance in the wires, check the wires themselves, as i said earlier, its ussually not what you were messing with but something around it.
i'd just go through and make sure your wires arent green.
tps shouldnt have to do with the starting, and completely disconnecting it can be brutal as ur car will either run too lean or too rich (which is why it bogs down) try replacing the tps and go from there.
