Ok so today was the big day, I got all the bearings in and was waiting for oil pump gaskets. On the 1989 D21 2.4L the oil pump is driven by the crankshaft and has to index cyl #1 tdc. The oil pump is external I must have went thru 10 gaskets because I had to remove it in and out 20 times before I got it right.
While I was waiting for the gaskets I decided I would replace the in tank fuel pump. I have been building up to that for 2 days. As luck would have it the tank was full. Anyway it went as good as possible. I put the truck on a lift and used a transmission jack and supported the tank that way. Everything went good and I don't have to worry a 25 year old fuel pump now.
Ok so I also replaced the water pump.
Everything went well and the truck runs great....
Now comes the rev limiter.... The condition still exists even with the new fuel pump.
I was told by somebody on the Nissan forum since my truck is a 5 speed the ECM has a rev limiter built in. However the ECM for the auto transmission does not have this. I have one(A/T), everything else is done, so now we remove the seat then swap out the ECM's put the seat back and be done with the whole thing.
