dead accelerator pedal?
Help! Fired up the truck, no problem....put my foot on the accelerator, and the pedal went straight to the floor!
Does anybody have a diagram of the cable linkage? I need to get on the road tomorrow.....it's a '90 E350
thanks!

The cable runs directly from the top of the accelerator pedal to the firewall. If you look at the firewall from the engine compartment you will see a black cable coming out and running toward the passenger side. On mine, it curves just in front of the turbo and heads toward the IP. I recently replaced mine because the sheave inside the spring on the cable itself had disintegrated and I got very little response from the pedal.

I had an issue with the accelerator cable going dead. Two areas: atop the accelerator pedal arm is a "V" notch that cuts into the small circular cable opening. The rubber bushing that was there originally tends to fail. Look behind the notch and if the bushing is gone, locate the very rear washer surrounding the Acc cable at the firewall. Move it in front of the notch on the pedal such that the pedal now has something to keep keep everything else from just slipping through the hole the notch connects into.
Item two the actual throttle connection clips onto a ball stud. Just behind this housing is a plastic tube 1 inch extension into the spring and slips over the engine end of the throttle cable. (THis needs silicon lube both outside the housing and down the cable train) This plastic extension tends to break off with age. When it does the lip of the cable housing sometimes jams and overrides the spring. Clean the edge if is long enough to minimize that from happending. If all else fails the throttle assembly is around $45 at O'Rileys ( just bought one)

I've been running that way for many months; it's worked great.

I had this happen, and my long-term solution has been to just get in there with a pair of plyers and break out that plastic extension -- it's totally not needed. Without it, though, the small return-spring won't push against anything, and you'll only have the main IP spring for a return. This makes the pedal a little weaker, unless you grab a stiffer spring to replace that main spring.

I am going to try filing a bevel on the extension to keep mine cable from hanging on it. I that does not work breaking the extension sounds like a good idea.
