Message My car has been down for a rebuild for 14months. I installed a new clutch saturday and cranked it up on jackstands to make sure in engaged properly and it did. Car ran fine and this was with downpipes only. Today i installed my testpipes and cat back,lower car and crank it up and its shaking like its down a cylinder and wont stay cranked without giving it gas. I found #5 injector had come loose (presumably from the shaking)so i plug it in and car still shakes when cranked. I pulled all of the spark plugs and they were wet. I cleaned connectors on tps,my "old style" ptu ,maf and cas. I drained the gas thinking maybe it was bad after 14months and put 2 gallons of premium. I pulled fuel line after the filter and had my wife turn it over and it was shooting out very good. Still wont crank now. Checked codes and got 55,all good there.

Im at a loss as to why it ran perfectly when I rebuilt it in october and also last saturday,and now 2 days later its crap. My car hasnt been driven since october because after rebuild my clutch died so it took me 3.5 months to get a new one and install it. My only thoughts are something electrical has become corroded or wiggled loose.

What if my testpipes or catback was clogged by a dirt dobber or animal? If it was comlpletely closed off could that be my problem?

I know my ptu is the old type but from everything i've read it either works or doesnt work. My car atleast cranked today the first few times i ran it. Im just very unhappy right now.
