2k maxima 150k. I have a starting issue, new battery, started crank sensors, plugs, coils and cam sensor. Also checked for continuity between ecu and sensors. On the first crank i get a spark. If i hold key down i get no spark. If i bump the key i get a spark only in the first crank. Basically i am not getting a continuous spark. Im thinking ecu maybe the issue. Any Ideas?
also all fuses and relays are good. ty

 

Could be a bad key chip or the immoblizer in the steering column that picks up the signal from the key.

 

Would the security light stay on?

 

sorry - not sure of that.

 

is the vechicle throwing any codes ?

 

Personally id suspect this being a immobilizer issue.

 

no codes. how do i troubleshoot immobilizer?

 

the security light should stay on if its a immobilizer issue. at least thats the way in works on all the acuras that i have worked on. but most of the time the car wont even get a signal for the starter so it shouldn't crank at all.

so with that being said i would lean more to the ecu being the issue being that it cranks but has no spark.
