I appreciate your help. and everybody else's help.  I just don't have the proper testing equipment to tackle it. I'm just going to wait till the shop has an opening for me. Next week. Hopefully I can get a van from work and continue work this week.

I'd have to ask my tow truck operator how much he would charge me the 35 miles there. He  probably feels guilty, he told me it was the fuel pump in the first place.

I let him know it cost me 225.00 for something I didn't need . I'll  ride his butt, see if he gives?

you should have tested the old fuel pump before you took it off. he gave you bad advise and you took it. if he wants your business again, and he should, he might work with you. i feel bad for you. this is a chapter from my life too.

After towing my truck to the shop today, and messing around with it for two hours. A younger mechanic started looking over what two old men didn't see. And in two minutes he found a 20 amp fuse that we both missed. And the son of a biatch fired right up! I could just scream!

 I definatly  am up for idiot of the year award.

It could be worse, it could be an intermittent no start. The scope of what it could be, could be from a fuse to a PCM. You'll be best served not tossing components to it, and getting a proper diagnosis, and repair. Sorry I couldn't help you. B)

I tried, glad it's fired! B)

start with the basics is rule #1. I get a lot of that kind of stuff towed in from other places who fail to start with the simple stuff and dive right in to changing costly components that were not bad. #2 rule is that most tow truck drivers are just that and its not too common to find one who knows drivability. Glad you got it done.

What caused the fuse to blow in the first place?

I had problems with the fuel pump relay in my '98 chevy dually..it would lose contact and shut down the pump. after that I cleaned the terminals and carry an extra relay in the console,its in the small fuse box on the inner fender. that and the cap and rotor are a poor design,seen a few problems with those.

The fuse was probably the original like stated, or like everything else on the truck. Quite honestly I'm glad I replaced the ignition coil, and the ignition control module. The truck fires a lot better an it has more power. Those too looked to be original. the camshaft sensor was an un necessary buy, I admit. And so were some other things.

 This whole episode is not over yet. When replacing the fuel pump ,I noticed the strap was ready to break from age, rust. And the return line was leaking a little. enough to order another one. And the fuel filler neck was rotted out. So I ordered the filler neck, line and straps. They all go in on Friday.

And them I'm done.....?

Probably not, but parts for those trucks are cheap compared to most other vehicles. The  power bump and  quick starting is probably due to the new pump. I don't recall where that fuse is in the system, but it may have blown from high amp draw from an aging pump. 

 

Fuel filter?

Manny hit it on the head. Old fuse.

Buttbeak, I replaced the fuel filter about three weeks ago, and as well as a spectre air filter. I noticed a big improvement in power  then. The fuel pump was replaced a year ago and was running fine. I had problems last year, put 4 different fuel pumps in it before I found out it was a bad wire going to the fuel pump. I ran a line from the fuse box to the fuel pump connector at the fuel pump. It has been fine since. It's also a Carter pump. I'm putting it back in when I drop the tank for new straps and return line.

I think the coil is the reason for the extra power and response.  I'm positive it was the original coil. It was riveted to the bracket on the back of the intake. They don't sell the bracket for those things. The ignition control module is also bolted to it.

 At least the damn thing is running. I can get back to work.

 Thanks every body, Till something else goes wrong.
