problem

i got my sr to start but the 2 bak pistions wont work, they have spark and gas but nothingthey wont move , my friend thinks it might be the ecu but idk, would any one else know whats wrong ?????

before you jump to conclusion take you hand and turn the crank shaft and see if the motor turns over there is a good chance that your motor seized up..

His engine coiuldn<t have seized up since 2 of the pistons work, last time I checked all pistons are connected to the crank.

he did say the back two doesnt move i was just telling him to turn over the crank and see if the pistons move it they move its not the ecu b/c you are manually turning the motor..

naw looked like i just need a new ecu :-/ now my engine is running like a monster

Your 2 back pistons didn't move, but the other's did? You replaced the ecu and they started moving? Does this ecu have magical powers to create connecting rods? Just incase you didn't know, pistons are connected to a crankshaft via connecting rods.... An ecu change isn't going to cause them to start moving.
