Help needed on TBI conversion
Hey guys, i know iam the new guy on here and this is a Bronco forum, however I really need to get this FJ40 out of my garage so i can get the bronco into it. I helped or rather dove into a TBI conversion on the installed chevy 350 however i'm running into a bit of problem trying to get the thing fired up. As I said he has a chevy 350 installed in it, i pieced together all the parts, computer, wire harness etc etc.. I have everything installed and wired up however I'm stumbling a bit on getting it to fire. I have spark, the timing is dead on and I hear the fuel pump kick on and see the fuel pressure hit 13psi when i crank it however still no start up. I think the injectors are not kicking on.. or i have something mis-wired however not too sure. I have been working on this by myself for the most part and not sure where to go from here. (complete newbie on this) As i said I know iam the new guy on here however I thought i would reach out and see if anyone has some experience getting on of these fired up and would be willing to lend a hand. I would be more than willing to float some $, food, or all the above to help get this rust bucket out of my garage. Thanks!

Re: Help needed on TBI conversion
You may get help here (I have been surprised before), but you may seek help over on , Coloradok5.com, Colorado4x4.org, or maybe an FJ-40 site as I am sure the issues are much more common there than here.

So what was it? Something simple I bet.

Re: Help needed on TBI conversion
I didn't supply 12v start/run power to the injectors. There are two service hookups on the wire harness I picked up (from a 92 camero) - well two of the wires going into the service connector were for the injectors and were not hooked up to anything.. hence no power. I overlooked it due to poor wiring schematics and honestly this was my first conversion.
Not any one wiring schematic helped me.. it was a conglomerate of 5 that eventually pointed the way. Then, a little trouble shooting and checking voltages ended up eliminating almost all problem areas and I was able to finally nail down the fact that.. hey.. no 12v, no fuel, no start.. and so i tied the injectors into the pink and black wire and it fired right up.
Glad I got it running.. set the timing last night and started putting the front end together. I think i can have it out of the garage tonight and get things cleaned before i work on redoing my powersteering/York/upper intake maintenance on the fullsize.. have a slight leak on the lower intake, new bracket for the York and I want to install a real Power steering resevior for my Hydro assist...
Anyway It was a good learning experience, even if it wasn't my truck ;)
I will be going EFI on the 76 bronco eventually - probably move the 302 from the fullsize (EFI, Mass air, roller) to the 76.. but we will see.. thats a ways down the road.

Re: Help needed on TBI conversion
I'm hijacking for a second, Zoso, have you ever seen this company: http://www.pricemotorsport.com/I can't link to the exact page, but they have an adapter plate to put 351W stuff on the 351M/400. Click on "Intake Adapters" then "AP-34". You should try it. Yeah. Chad

Re: Help needed on TBI conversion
I've got a 460 in my bronco. And the only downfall with goin to stock 460 efi I would need to change the heads to the efi ones. It wouldnt be cheap with my valve train. Thats why Im just lookin into a tbi setup. I really like the fast ez-efi as it's bolt on and is self tuning.

Re: Help needed on TBI conversion
Sorry for the unnecessary hijack. I saw those adapters a few years ago when I wanted to put a 400 in my Bronco.
