Possible Major Problem!!!!!!!!!!!!

[climbcovey]

This might be simple.......I hope! Got in the VX this AM started her up. worked like a champ as always. Put'er in reverse and she died immediately. Back to park, started right up. reverse.... died immediately, repated this drive died immediatley, neutral started, back in gear... died. Had to leave for work so took the old truck. Going home in the morning to figure it out but don't know where to start, any suggestions? last week I threw a trouble light, dx'd as code for manufacturer installed emmissions control. but, this code went off with next start up, and did not recur. thanks guys for the help.

Sounds like the MAF is unplugged or has fallen off the intake tube.

Checked the MAF, all appears to be intact and connected properly, I had driven the VX the night before, >100 miles without any problems, and it still starts up like a champ, will rev up, run smooth, no detectable problems....until I put it in gear. then it dies, runs/starts fine in nuetral too. any other suggestions.... please!!!!!
just ran the codes, P1404, P0101... Manufacture controlled auxillary emissions controls, and MAF or VAF ckt range/perf..................any input?

Tone, using the reference to MAF you gave me plus the reference disc (also courtesy of you) Iremoved and cleaned the senors circut with electrical cleaner. While I was at it I also cleaned and lubricated (with electrical lube) all other circuts of the emmisions control system (o2 sensors etc). when I was finished the VX started and ran like a champ! So once again thank you for your commitment to service knowledge of the VX. I was serious about the beer! I plan to catch up with you sometime at a VX meet or somewhere. When I do, the drinks are on me! My new job allows me alot more free time now, I only have to work 119 days a year at my primary job! So, keep me posted on any meets you plan to attend. Thanks again!

Well it ran fo a day after cleaning the MAF, then same problem occurred, I replaced the MAF sensor, but no help. Going to check the fuel pressure next, any other suggestions? Has anyone else had this problem? Now even if it starts in park, it won't stay running when I give it gas.

I've had a problem close to yours, but mine one day wouldn't start at all. I found the fuel pump fuse (under the hood on the right side) was blown. I had a shop check the fuel pressure and it was low(can't remember the pressure). I replaced the fuel pump and have had no problems since, and it was over a year ago...Good Luck
