replaced fuel pump, now what?
I have been having an on going saga with my 89 TBI EA(330k on the clock).
I have just replaced the head gasket and also needed to change the fuel pump, I did some tests on the pump and it was not up to spec. anyway I did the head gasket first, started the engine after I had finished, all seemed ok except it was running like they do when the battery has been disconnected and the computer has lost it's mind.
So I replaced the fuel pump ( isn't that fun!!)started it up ok and proceeded out to do the set up thing on the computer after I had disconnected the battery to clear it's memory and reconnected it, it was hard to start and only started after I pushed the accelerator down a bit, I did the setup on the computer all ok the idle is back where it should be and the engine seems to be running ok but it is playing up on start up cold or hot.
The only thing I can think of is perhaps the injectors don't like the new pump and they also need changing(to my knowledge they are originals)
Any other suggestions.
Also when I did the head gasket I only had the battery disconnected for a moment I thought they had to disconnected for about 10 min or so before losing the settings.
