Before you say CPS: I HAVE SPARK!!!!
So I was going out to a client site down in socal after just driving down from WA in my 1990 XJ, parked last night over at my parents, this morning I saunter out, throw my tools in the car and start heading to work. Anyways, the vehicle started (but was running somewhat rough). I drive down the driveway and around the block to the main street... kapow vehicle dies and won't come back. Luckily it didn't happen on the drive down, or the drive back up.
Anyways, so far I've put a sensor on each of the plug wires, and it's showing I'm getting spark, regular and constant. I'm thinking this might be fuel related (going from non-ethanol PNW gas, to crap cali gas).
I'm not frustrated yet, but I certainly am annoyed.
I'm swapping the fuel filter right now, while I'm under there I'm going to check voltages and operation of fuel pump. I did check for presence of fuel in the rail, it doesn't seem to be getting the normal high-pressure spurt, which makes me think either fuel pump or regulator. (possibly ballast resistor)
I rented a fuel pressure gauge from vatozone, however it seems to be broken, measures zero pressure, and pumps gas everywhere. Oddly, it seems they had the presence of mind to epoxy the fittings onto the FP gauge so I can't simply remove the leaky part.
Anyways, I would appreciate any informed opinions about this, and yes, the CPS was the first thing I checked, so please for the love of God and all that is holy DONT SAY CPS.
