hey i think my ecu has burnt out that is y my car is not starting, would any ecu from an eg work or would i have to get the one that is in there which i think is a p28 for an ex motor. so im able to us an ecu from lik eg same year as my car but differnent model as a cx. would that still work, i just wanna c if the car will start and if the ecu is the problem? thanx

 

yea that would work to try to see if the ECU is the problem.

 

did you check all the fuses? main relay?

What makes you think it is the ECU?

Does the car crank? Have you checked to see if you are getting spark? What exactly happens when you try to engage the starter?

 

there is no spark and no fuel, i have checked the fuel pump, main relay an all fuses also the ignition fuse n everthing so the ecu i think would be the problem also when i try to crank it trys but no fuel or spark

 

yes it will work but it wont have Vtec sence those cars do not come with those? try it if u can borrow one.

 

yup thanx thats what i was planning to do i just was nt sure it would work

 

do it and get back to us and, see if it worked

 

hm, i have yet to hear of an ecu randomly die out, however im sure it is possible. it sounds like youve checked everything over though, so maybe it is your ecu. youll definately wanna get a p28 though. if you somehow find out that it wasnt the problem, you could always ship the extra p28 my way

 

I get ecu's all the time that have just crapped out for no reason.

As everyone has said, check all the connections, then go from there. You should also try your ecu on someone elses car just to see if it is your ecu.

 

the ecu is not the problem i swaped with my friend, my ecu works in his car, and mine still wont start. any hints or answers

 

Main relay? Are you sure you have all the ECU plugs inserted all the way? I've had that happen more than once.

Also, are you getting power to the ecu? If the main fuse under the hood is blow, then you'll get nothing. I think it's a 7.5 amp blade type fuse.

 

well it appears that the ecu isnt hte problem. then again working with a honda salvage yards its very rare to see an ecu burn out on its own, usually it takes flooding, an idiot in teh wiring, or some orhter sort of thing happening to cause an ecu to fail.


by any chance can you here the fuel pump prime whne you turn the key to the on position?
