OT: Ford F-150

[MoMike]

My '91 died Thursday. My wife started it got part way down the lane, and it died. Changed the module, still nothing. There is a notch on the balancer which when you line it up with the timing tab. Is this a timing mark?

Dual tanks? Spark? Fuel pressure?

Is it a ignition or a fuel problem?

As I recall Ford had problems with dual tanks switching properly in the late 80's and early 90's.

Electric fuel pump relay problems in 91. I believe you have 2 relays and 2 tanks with pumps inside. Troubleshoot

I had the same problem with my 250. Ran great and did the same thing you describe. Easy stuff first, make sure you have fuel in the tanks, listen for the pump to cycle when you turn on the key. If that's a go, check for spark at the plug and remove the dist cap to make sure the rotor is turning (if you're cap, rotor, and wires are crudy and flakey it may be time to replace them). If no spark, about 90% of the time it'll either be the coil or module in the distributor. Because of the labor prices here in Germany and the fact that these trucks aren't common (lot of headscratching and guessing) I ordered a complete dist and a coil from Rock Auto (cheapest place I found that would ship to me) and replaced both. My problem was the module in the dist. You can get just the module and replace it, but the few extra bucks for a complete one is worth it. I've fixed many a problem and received plenty of help from this forum:

Yes, the mark you are talking about is timing marks, but you can be 180 degrees out. Don't really see timing being your problem in this case though.

Good luck and don't let it give you a nervous breakdown. Sure wish they would have todays efficiency with pre '70's simplicity.
