Truck is a 88 5.7 "K" engine 4X4
I am having problems with hard starts after the engine is warm and the truck sits for say 20/30 minutes. Then when it does fire it runs real rough like it's flodded out. It will clear up if you clean it out. Also the thing will hunt or surge at idle when warm. It does not run 100 percent anytime right now.
I have done the basic's so far. Make sure the plugs/wires cap/rotor are in good shape. The timing is set and working proper. I know the engine is healthy because it only has 15,000 miles since i rebuilt it. I also installed a new fuel pressure regulator, I only got 1 code and that was 2 nights ago and it was a 44, (o2 sensor went lean)
Now some questions. I want to check the fuel pressure next, but as you all know there is no port to do that, so what typ of fittings have you made/ bought to check fuel pressure??? What is the correct pressure???? Any other ideas about what to check??
