I have no signal to the injector so car won't start


Asked by Sep 11, 2016 at 07:40 PM about the 1990 Nissan Sentra XE Coupe

Question type: Maintenance & Repair

Car would not start.  It had good spark and fuel to injector.  No signal at the injector plug.  Replaced the ecu and car started instantly.  Brought to temp and cycled the fans a couple times.  Started several times and called it a day.  Started right up the next day so I put the air cleaner assembly back on.  Now it won't start again.  Pulled the air cleaner assembly back off and there is no signal to the injector again.  Getting code 55 from the ECU which isn't even supposed to apply to this year.

is there a way to check the CPS without removing the distributor?
