Hey so I’ve got a 94 civic d15b7-t. Bassicly what’s been happening is randomly while driving I’ll get a cel and it bassicly looses all power until I cut the car off and start it again, boom back to normal no cel. Yesterday the car died but wouldn’t start again. Fuel pressure is good, no codes but a solid cel, no boost leaks no vaccum leaks just 0 spark coming from the coils. If it was a distributor I’d think I’d have a code 15 or something for the icm but it has nothing showing up when I jump the clip. How can I test the ecu? It’s a chipped and tuned p05(I know I’m not suppose to run that lmao but it works temporarily)

I can get access to a p2E ecu from a 97 dx to test it if that’ll work.

 

Test icm in dizzy

 

Check grounds and make sure all are clean and tight. Next, test with a "known good" ECU to start the car. If it fires right up, it is likely that the ECU is the problem. To be sure, immediately unplug the "known good" ECU and re-connect the chipped ECU and crank the car. If it fails to start and/or doesn't run, your problem is the ECU.

 

got a new dizzy, have spark now, still no start. Timing marks look right and you can smell fuel on the plugs

 

bought an extra p05 off a parts car, still no start.

 

Check your spark plugs and see if they are fouled/black. Clean or replace them and try and re-start.

 

If your running a stock ECU make sure the Injectors, Map sensor are stock,

If you do have aftermarket Injectors and 3 or 4 bar map sensor, make sure those are selected and saved in the ECU parameters.
