I've been thinking about getting an older Cruiser - cuz I spend time on Ih8mud site. I imagine you go to that forum?

Anyway, about the rails: Yes, you got it. At the fuel rails - the 1/4 SAE connection. But let me tell you my experience: I was checking the fuel pressure at that point, during idle. Pressure was within spec. But the minute I tried to accelerate - the car would bog down. After weeks of trying different diagnoses (what's the plural of diagnosis?)...all to no avail...I decided to change the fuel filter. I'm serious - it was like a different car. It was the problem = a "partial" blockage in the fuel line system. Enough gas was getting to the fuel rail (and thus the injectors) under idle...but when the engine was using more gas...it (gas) wasn't being replenished fast enough.

So, while I'm not saying your problem is the necessarily the filter...it still might be a partial blockage in the fuel line. You're getting enough gas during idle so that the pressure reads fine at the rail - but not enough when accelerating.

The filter on your car is underneath - right in front of the passenger side rear wheel. There's a black plastic cover - protects/covers the fuel pump and the filter. There's about 6 plastic nuts holding the cover on. Between the pump and the filter there is a short run of fuel line - makes a 90 degree bend. You might want to look and make sure it's not kinked or anything.

Like I said, this might not be your problem. But it was definitely my problem and was a cheap fix compared to some of the electronic stuff you've been looking into.
