got my engine in my impreza..got all the wires hooked up and tried starting it up. fuel pump works starter works compression is good on all cylinders. but i have no spark..help anyone??? so...what could be the problem? anyone???
no coil, its coil packs on plugs... check the harness that the packs plug into, then check ECU connections
everything is where its supposed to be...argh! man...this is frustrating...!!!! what else can it be...what can go wrong that wont let it spark???
well..im goign to go back and try it again....so...(crossing fingers) checking my wires again...and then going to crank it again...
sorry, I don't know anything about the car you're running. is it a swap? you say the fuel pump works, but how? do you have it wired correctly (via the ECU)? or do you mean if you manually give it power, it pumps. I think the fuel pump circuit is a great indicator of whether or not the ECU is wired up correctly.
are you getting ignition at all? if the answer is no, check the harness and the connections again, check the plugs when your cranking it over and see if your even getting a signal. i know i had dead coil packs on 2 cylinders, fairly common on EG33's... also, check ALL of the sensor connections, its easy to overlook something small... if its getting any spark at all i would look towards coil packs or even something as stupid as the MAF and O2 sensors and their connections, mine have given me problems in the past. hope you can figure it out soon man, if your still having some problems give me a shout later, you got my cell number.

ok..now...when i tried it...my ecu fried! yikes!! well..i guess i have to get a new ecu and new wires! darn it....but i guess its fine now...so...thanks though everyone... dao
