I have an 87 4Runner w/ a 22re. My problem is that i'm losing fuel pressure almost imediately after shutting off engine. When i start my truck in the morning it starts on the first turn of the engine and runs fine. After i drive it and shut it off i can wait 5min or a couple of hours, then crack open the bolt at the bango fitting on the cold start injector and i get no fuel spray. If i try to start it, it will turn over and fire on a couple of cylinders, die, turn over a few times, then start and run normal.
Fuel pump? Injectors? Cold start injector?
Any help would be much appreciated. Thanks.....
