Thread: 1991 Lifted Z71

Well guys as I said in my Gtp thread I was getting the truck back out, now I like to think I know a lot about tbi 350s, and I know them better than 3800s, but I am just swamped on this part of the truck, im going to ask it here any way idk if any of you guys have messed with 1990s tbi 350s. So here is what I have to say, and I wanna see if you guys know what this problem could be. Any way first of I was driving the truck around one day, then I decided to put my 88 gauges in, so put them in, then I got smoke out from under the dash, then I put my 91 gauges back in and they worked, but now the truck is getting no spark, it turns over, fuel system is working good, but no spark idk what the he*l it could be, I think I found the wire that burnt under the dash and I fixed that!?!?! So now I am just stumped! If any body knows what this problem could be any help would be appreciated!

Did you pull a plug and touch it to the block to see if you have spark while you crank it?

Yeah, no spark at all

I forget if those older trucks have IGN fuses somewhere in the truck. Could be burnt if it had one.


Have you looked at the coil and cap/rotor yet?

Just looked at the cap and rotor and they looked good, I replaced them in the fall, are the IGN fuses the big silver ones, in the fuse box?

Look for this fuse box inside the cab, check any fuses that deal with the computer, igntion system aswell.

I checked all the fuses and idk how to check the fuses on the far right the "power" fuses. but other than them two they are all good.

I think its the coil, im going to pick one up tomorrow, thanks for the help fivefingerdeathpunch its appreciated

Are you sure your ignition switch is ok?

Yeah, its brand new

It was the coil, she is fixed! Thanks for the help every one! Its appreciated!

Well one think after another with this beast, The rear main went out, I started it and it dumped like 3 1/2 quarts out on the ground, so I am getting ready to pull the engine out, I have the front off (alt, water pump, and what not) also the manifolds, and most of the wiring. Tomorrow the transfer case is coming off, and it will be out. Then me and my dads friend are going to do the rear main and we are also going to put new bearings in it, because the oil psi is very low from running 15w 40 in it in the winter (wind-chill was well below 0), not very smart my friends! Anyway here is a pic of the progress!

Please clean it before you put it back in lol

Yeah that would be a good idea lol, also wanted to paint the valve covers and what not but that will happen when it happens lol!

Just put this thing together to hold my oil psi gauge and have 3 toggle switches on, its not the best but it works!

A lot of improvements could be done but nice truck treat her good. I have had a few that I've reworked and made nice
notice the rear fenders over the wheel

Now look this side was completely gone!!

day of getting it
and then my other ugly pile no parking brake so put it in the ditch made or a nice pic

did this right after that pic

then after with no buff no clear coat no nothing it's tractor paint


the orange one was a 75 ford f250 factory highboy 3 inch lift factory with 35's

and the blue one was a 1980 with 6 inch lift and 33's

thanks man, im not a ford man, but those were some nice looking trucks! I kind of want to fix the rust and paint it flat black, but that's after all the little problems are sorted out!

Plastidipp and it'll be cheaper I'm a cheap bastard lol the green was John deehre green with black added and the white was primer sold the truck that after noon lol

haha nice, and that is a good idea!

Got a guy here in Wichita that plastidips cars professionally if you want it done that way
