Still chasing injector issues.

[Jay Kempf]

I have been chasing dead injector issues for a couple weeks. Swapped a bunch
of parts and did a lot of electrical diag and have gotten down to having
watched #5 quite on me as well as the original #4 problem. I have checked
and chased everything back to the ECU. 

>From what I am looking at in the wiring diagrams the system is a ground
fault injector control. I have working injectors and continuity on all wires
back to the appropriate pin on the ECU but originally no firing on #4 and
now #5 is going in and out. Plugs are all good and spark at all holes and
compression is good all holes. Pull connectors for #4 and #5 and no change.
So I have a 3 cylinder engine now. The funny thing is the instrument cluster
came back and I got a self check and "OK" today.

Before I go buy an ecu I would like a conclusive test even though I think I
already have pretty much traced it back to there.
