I have a 1994 acura integra and it wont start or spark. So i did tests on the icm wires and the one going from the icm to the ecm is not getting continuity so what do i do? Whats the easiest way to trace down the wire and check it?

 

your distributor probly went out... its a commen problem on pre 96 integra's, it's happened to me 6 times!

 

What do you mean "no continuity" and are you talking about the yellow/green ign. input signal lead.

Do you have 12V+, [when ign. switch is on] on black/yellow lead going to coil and ICM.? 94

 

the guy before i had it said he put a brand new distributor in it..... and im saying there is no continuity from when when i put a multimeter from the yellow green wire at the ecm then put the other prong on the yellow green that plugs to the icm there is no continuity between the wire and yes i get like 12.3 volts from the yellow green wire..... see when i turn the ignition on there isnt power coming from the yellow green wire at all..... but i have 12.6 volts out of the coil but when i crank it it drops down to like 5 volts so?

 

Then there is a connection problem on the yellow/green someplace between the ECU/ECM and the ICM.

How about between the ECU/ECM and the yellow/green at the distributor assembly plug?

Is there voltage on the yellow/green at the ECU/ECM?

Run a jumper from the ECU/ECM to the distributor, temporarily replace the yellow/green, you can just run it out the door to test. 94

 

Alright i'll have to check the yellow/green at the distributor plug..... and if theres no voltage i will run a jumper thanks for your help.... but what does it mean when theres 12.6 volts with just the ignition on at the coil then when i crank it its goes to 5 volts and no spark still?

 

Could be an ign. switch switch problem, check the voltage on the black/yellow lead in ign. switch harness when cranking to start. 94

 

so I ran the jumper wire from the ecm to the icm and still no spark but i got voltage finally
? what now?

 

Have you tested the ICM itself and/or the coil? 94

 

i ran the tests on the icm and they came back fine and i tested the coil like it said to and its fine so?
