How to check fuel pump/injectors?
#2
I think the best way to test the pump is by checking the fuel pressure with a gauge- I've never done that, so I can't help you there. The injectors can be checked by ohming them out- should read between 10-14 ohms. If they're over that, they're either out or on their way out.

Ok, I know how to use an ohm meter and such, but where are the connectors for the injectors? Do I have to remove any of the manifolds just to test these? Anyone have a write up on how to test them? Any help would be appreciated. Thanks

Fuel pressure is easy to check. Go to the local autoparts store and get a fuel pressure gauge. The easiest place to check is at the Fuel Filter. Just pull the rubber off and attach to the T coupling (should be included with the pressure kit) and then run more rubber to the filter. You'll want to do it before the filter to check the pump, and then after the filter to see if that is causing you problems.
Actually, anyone know how often you should change your fuel filter? It's been at least 12,000 (in 3 mo's) miles since I did mine.

my injector harness/connectors have green crap built up inside of them, wire to connector side, when i move then around the car almost dies.... does anyone have this problem
i tryed cleaning all the stuff out with connector cleaner and dielectric grease but i cant get in the top of thoes little connectors , (under the boots, cuz there split open), has anyone replaced these parts?

Take the clips off by sliding them off the connector- then the connector will pull off straight up. Once you have the connector off, you'll see the 2 pins on the injector. There's your contacts for the meter.

at idle :
VE = 36 (with vacuum connected)
VE = 43 (without vacuum connected)
