no no no no.
Current ramp means to hook up an amp clamp around the injector power wire. Then run the car and look at the pattern that is created using an oscilloscope... expensive tools but VERY useful.
If oyu have the tools, the pattern should ramp up at a 45* angle(ish) and peak around 1amp. Around the middle there should be a little blip where the pintle overcomes the spring and pops up. It should be approx 3m/s long, IIRC.
Another great way to check is using a drop test. Get a pressure gauge and put it on the fuel rail. Run the car, note pressure. Use an injector pulse-er (another piece of test enquipment that you plug into the injector that turns it on/off) to pulse each injector 50 times. Not the psi drop in fuel pressure of each injector. Make sure to start/ run the car briefly between each injector as well. The psi readings should be within 1-3 psi. The lower the psi, the less fuel the injector delivered, and the more gummed up it is.
You may find, as well, that you lose fuel pressure when it's just sitting, and I'm assuming that it very may well do that, because the injectors will be leaking fuel. That's also why it's hard to start.. flooding it out. If you want to abosolutely 1000% diagnose them as leaking injectors, pinch off the feed and return lines to the rail and watch the pressure drop. If it bleeds down after pinching both of those lines it's the injectors leaking.
You'd probably have the best luck at a junk yard.. .find a smashed car with low mileage with a 3400 and pull the entire rail... they'll prolly give it to ya for $50.
