I replaced my tranny with the neon 2002 tranny, after finishing i wen to start car and it will not start. I took out th ecu and left it in my garage for the week i was putting the tranny in. I replaced spark plugs, wire, ignition coil, camshaft position sensor, and crank position sensor. I am wondering if i should replace the ecu. I want to hear a second opinion before buying another ecu. I cant think of anything else, i check wires and all are fine. I check power through the wires with a multimeter and they were within the normal ranges(volts). When i check for spark with the plug(with wire) grounded to the intake manifold, i get no spark when trying to startm but i checked the harness and when cranking the car i get 12 volts from the middle wire. Please help, if possible.

Is your fuel pump priming when you turn on your ignition? If you don't hear any noise, then your fuel/asd relays by your brake booster could be bad.

Yeah, my fuel pump did prime. I found out i fried my ecu by plugging in the vss and the coilpack harness backwards. I guess i wasnt paying attention, but i got another ecu and car turns on great. Now i just have to wait on a downpipe flange and i can feel my new precision SC61 turbo and neon tranny thanks for replying.
