On a recent drive 1986 GN seemed to go into Limp home mode. At home I hooked up a scan tool, but could not get connectivity with the ecm. I wrongly thought ecm was defective and replaced it. Could not get connectivity with new ecm. What am I missing? I have not driven the car since. Any ideas...

It was the ignition control module- Thanks to all Dave

SalvageV6- Thank you- what levels or types of signals should I be looking for- will probably borrow a scope- Thanks Again, Dave

Is it possible to check some of the engine sensors thru the ignition module connector? Cam sensor, crank sensor? Thanks, Dave

Just finished an engine rebuild and car was running fine. Was running an errand and shut the car off for about 10 minutes. When I came out the car would crank just fine, but no start. Towed home. Has fuel pressure at rail. Injectors are pulsing. No spark on any plug. Circuit 839 (M) on harness...

Need belt tensioner assembly without a broken ear- please advise price and shipping- Thanks, Dave

In the process of reassembling my motor after the two center mains went out. I have a fairly new radiator that has always run cool. But, I need to replace the engine oil cooler because of metal contamination. I have a shop that will do the work, but cannot locate an original or aftermarket in...

Thanks williamsGN- my radiator shop said he contacted all of his suppliers and the original style oil cooler was no longer available- What I would like to do, in descending order is: 1-Replace with factory style cooler-or aftermarket 2-Some kind of air cooled cooler- 3- No...

Had to rebuild the rotating assembly after the loss of the two center mains. Now I am making sure there is no metal left to contaminate the new engine. I would like to have the radiator engine oil cooler replaced, but the AC Delco part number (3039077) is no longer available. Does anyone have...

Thanks Heg87T

:) On the radiator oil cooler which is the inlet and outlet? Top? Bottom? Thanks, Dave

As a point of interest the block was line honed with the girdle and head torque plates installed. The mains were shedding copper big time.(chunks)

No backfires or anything unusual. This will be the fourth teardown on this basic build. The first three were to resolve a ring seating problem with Total Seal top rings. Did the whole shim thing with the girdle and everything seemed good. Obviously there was something not right. We'll be...

I don't think the cap machining was the cause. Jason Cramer did the machining for one of his girdles. I hope you guys are right about the crank causing the false knock. It would explain why the engine ran so poorly. Thanks for all the feedback. Dave

No pictures- according to the Clevite site pictures, it was either a bent crankshaft or a misaligned crankcase- we'll work that out- I am really curious about the knock sensitivity. Could the knock sensor have been triggered by the crankshaft noise?
