My problem is a 1990 RR. After driving vehicle for 10 or more minutes, can be over 2hours, the vehicle will just die. I can be going 5 miles per hour or 70 MPH and it will die, there is no relationship with acceleration or not. It will die if I am accelerating or not. It had code 48 show up when the check engine light went off, I should say it was idleing erratic at that time, but hadn't died. I changed the stepper motor,but it didn't fix the problem. I had done a complete tuneup, including plugs, wires, cap rotor, breather system, fuel filter. Larry at RCH did a diagnostic and said it was the TPS, changed it still dies, checked coil it has spark, checked igntion module it has spark, I checked MAF wires look clean. I have narrowed it down to either fuel relays or fuel pump, what do you think and did I overlook something. | ||

MAF itself could be bad. You can also try wiring the fuel pump to a switch and drive it like that for a few weeks see if you still get the problem, or just replace the fuel pump relay itself, they are not that expensive and a local autoparts store should be able to match it up. Last 91 RR I owned had a bad fuel pump relay took it autozone and the guy at the counter spent about 5 minutes looking for a match and found one, only cost about $15. I also did the same thing with my A/C compressor relay on my 96 Disco, again autozone matched it, and it was only $12. | ||

I had a problem with my Disco and it ended up being the Coil, change it and run it for a while, if that does not work you can always take the Coil back to the store for a refund. |
