hard start rough idle
1992 xj6 92,000 miles
This car doesn't get used everyday. Typically once or twice a week. It has had a slow battery drain since it was purchased about 10 years ago. That's a question for another day. Right now it has a starting issue.
New battery. Car will turn over but not start. Hasn't had a tune up so I replaced the distributor cap, rotor, spark plugs, wire set, air filter and fuel filter. The car did start after doing so but only after I held the pedal all the way down. Ran very rough and only smoothed out when the RPM's were over 2k. Once they dipped below 2k, it became rough again and by the time it dropped to 8k, it would stall out.
I started it again and placed the transmission in neutral with no change (same RPM conditions as above). When I put the car in drive and let off the break, nothing happened. I had the pedal all the way to the floor and the car just sat there. After about 30 seconds, it started to crawl forward but never more than a crawl. About 10 feet later it stalled again.
Just to clarify, there is no option to scan this car (I have an OBII scanner) is there? I didn't see a schrader valve on the fuel rail - is there one in the engine compartment that I can use a fuel pressure gauge on to see if I'm getting enough fuel in the engine?
The fuel that came out when I changed the fuel filter did not appear to have water in it. I checked the container before I put everything away and did not see any separation.
thanks in advance for any help.

You need to post in the XJ40 forum to be sure of an answer. Although it says 1992 on the forum title this only applies to the XJ12s with the 12 cylinder engine, the sixes finished in 1986 when the XJ40 model came out with its AJ6 six cylinder aluminium block engine as is fitted to your car.
