my rx with 13b motor wont start, getting no spark. changed coil packs,computer,and the cmu? distributor thing but get no spark. recently took back lense esembly off to prime car and stop light started coming on after put back on? put a radio in and had to figure what wires are for what and ended up tapn into dome light so battery kept going dead fixed so it was wired diff and stayed charged. before work one day i went to start it to check if battery was charged and was but was running rough so i adjusted timing and ran pretty good. after work i started to double check and it ran like a bag of crap, and died wouldnt start again. now the days i drove it everytime i started it the idle wud jump up and down for a bit then leveled out? so if anyone has ideas on whats going on please speak up lol

did you set the cas (the distributor looking thing) right cause that can cause it to run like crap also if you list the year we can give a little more feedback along with any mods relating to engine

thatpoorguy

Are you sure there's no spark? Like river said if the timing is off it will run like crap or not start at all

I had this happen a few years ago. Mine was the Mass Airflow Sensor. No signal to the ECU, no spark. I picked one up from a salvage yard.

I have the same Issue but i replaced The Cas, Ecu/wires, TPS, Coils Trailing/leading, everything that has to do with the Ignition system But the Ignition switch. no Spark still.

RicerJ

have you checked the ignition wire?

AdamMaxwell

For the Ign switch? or a wire on the Ecu?

RicerJ

yea for the switch the wire that comes out of the main fuse
