88 BroncoII with fuel problems?
First off, I am in Guam, USA, so I have little access to reliable mechanics. I recently purchased what is refered to locally as a "Boonie Car". It is a 1988 BroncoII, 5 speed with 91K miles. It is in pretty good shape, except that it seems to have fuel problems. It will idle decent and starts up right away, until.....I drive it under any load. I can putt around in first gear alright, but it seems to drag and won't go above 3000 RPMs (guesstimate, no tach) while in gear. It will rev up just fine in neutral though. Once I get up to about 45 miles an hour, which takes a while, it starts to sputter, and then it dies. If I let it sit for 5-10 minutes, it starts up again and the adventure begins anew. I tried to listen for the fuel pump when I turn the key, but I don't have any reference on if it is loud enough to hear anyway. I went ahead and bought a new external fuel pump anyway, but if anyone has any ideas or experience with a problem like this please let me know. Oh yeah, I know very little about engines, and I am shooting from the hip

Welcome to FTE!!!
The first thing I would do is determine if the no-start is due to lack of fuel or spark. The TFI ignition modules are known for problems when hot.

Well, I think I have a good spark, the engine doesn't seem to be hot or anything, at least the temperature gauge doesn't indicate it. It doesn't get much above the halfway mark. I need to check the spark I guess. It does have new plugs that are properly gapped, and new wires as well. What is the best way to determine if its spark or not? If I don't respond in the next few days, I apologize, the news says we have a typhoon headed this way again, and we are still recovering from the big one in December, so my ship is pulling out for typhoon avoidance. I will check the spark, and replace the pump as soon as I can, weather permitting. I will let you know what happens either way. I appreciate the help, this looks like the beginning of a long hobby.
Thanks,
Chris
