First, there are three types of 'cold start' issues:Along these timing lines I have a question to propose. My pump and injectors were both replaced 100k miles ago, from Oregon Fuel Injection. This year I pulled and tested my injectors, 2 were bad and the other 6 were low pressure. So I replaced them, but since then have had a very hard starting issue when the engine is completely cold. Could this be timing or should I look to fuel return? And before anyone asks, no I don't have a meter so I don't know where my timing is at. I took it to a shop who had a broken meter (learned after I got there) so I can't give a baseline.
I dont have a square on my pump.Update. The starting issue was fuel return related. I did the whole return kit a little over 2 years ago, so it's likely that in reinstalling injectors I damaged a piece and caused an air leak. However timing was retarded with the new injector/old pump setup. So I did have to advance to get back into the range of 8-9* BTDC. Like the op I was closer to 4*.
Two pieces of advice for those doing their own timing. A 3/4" end wrench fits the square block on top of the pump perfectly for rotating, and this Snap-on wrench will allow you easy access to the three nuts holding the pump in place.
