I have a 93 F150 4.9L I6 with a bad problem.

I was driving two weeks back and it just cut out and died. Towed it home and found a maxi fuse blown. I put a new one in and it blew again. The next day I put in another fuse and the truck started with a real bad idle and acceleration problem. And when the truck first started fuel ran out the tail pipe, the fuel out the pipe has stopped. Here is a list of things I've done so far:

HEGO sensor
Throttle position sensor
cap/rotor
plugs/wires
ignition module
new computer
ignition coil
Vacuum test
If I disconnect the #6 wire from the plug the motor doesn't idle down like the rest do. But if I disconnect the fuel injector it does. I did a Ohm test on the injector and it tested alright. I'm not getting a check engine light or codes. Where should I go from here besides the dealer?

Thanks to all who have some advise.

Which fuse did you blow?

 

It controls the fuel pump relay and the EEC module. I tried replacing the computer thinking maybe it got damaged when the fuse blew out but no such luck.

Thanks,

If I were you I would check fuel pressure. Did you put in a larger fuse the last time? I am just wondering why it would blow twice and not again. How many miles are on the truck?

 

I used the same 20 amp size fuse. I wish I could answer why it did not blow again. I have been working on this everyday for the past 14 days. We checked my timing last night. The timing mark stays at 6 o'clock no matter if we lift out the distributer in do it properly.
I want to bring it some where but every place I talk to said $125.00 for the computer test, another 3 to 4 hours @ $77.00 per hour just to figure it out. That is alot for it could be this or could be that answer.
