I cant find what this = ECU or igniter or??

An 84 CRX with a b18 is nothing to hold against you. That would be one sick whip.

As far as your problem goes, are you getting spark? Fuel? Is the engine turning over strong?

 

Spark is ok but not sher i think this is where my problem is??
got fuel pres at the filter and if i open the rail end plate there fuel
it cranks strong
I've been look for a noid light to check the ecu and injectors this would help rural out this part


You don't know when it will or won't start

Know it's a 1984 CRX with a 88 civic wringing harness OBD0 PR4 90-92 b1.8A1 was up and running Fuel pres was low 22-25 So changed the Pres reg AJ type up pres to 35 -39 and then it started to do this start won't start

Any thought.

No codes ....know it code 15
OK it cranks
IF it runs it runs but you dont know when it wont start

As of today 8-2-07 I've found a problem with the main relay If you number th plug like ECU plug

My ?? is Yel/Blk there two wires one to pump one to injectors pin 2 or pin 6

1 Grn/Blk two wires go to ecu pump input
2 Yel/Blk ???? pump or injectors
3 empty
4 Blk/Yel power in run /start
6 two Yel/Blk ???? pump or injector
7 Blk ground
8 Yel/Wht Power all the time

8/3/07

1 Grn/Blk two wires go to ecu pump input
2 Yel/Blk fuel pump
3 empty
4 Blk/Yel power in run /start
6 two Yel/Blk ECU/ injector
7 Blk ground
8 Yel/Wht Power all the time

What i found was that power was not getting to the injector resistors
This is a 84 CRX with 88 wring harnes and a 91 B1.8A1 and one of the wires was not connected I rewried the main relay like a 90 integra main relay
ALL GOOD
