I bought a low mileage (supposedly) TPI 305 from a junkyard. I would like to run a leakdown test (which I have plenty of info on), but there is one catch. The motor has to be warm. I have an extra harness, ECM, and MAF laying around. Could I make this work with some sort of a junyard fuel pump? Not looking to run it for a long time, just enough to blip the throttle and warm it up. Also, I do not know a whole lot about wiring or electricity, but it would seem to me I would use by battery charger as a power source for the injectors and ECM. Would this work ?? Any help would be greatly appreciated. Thanks guys!

 

I wish there was an easy answer on this one but its going to be a massive pain to get an uninstalled engine running unless you have a spare TPI harness you can do a whack job on


Either way the thread goes to the top and hopefully somebody can give some insight

 

I got my 355 TPI running on a test stand before I put it in my S-10. The advantage I had was that I had to cut the fuse block plug anyway to splice the wires into my S-10 fuse block plug. So I cut the F-body plug, hooked the wires up to the external gauge cluster, ignition switch, and battery. After everything was running, I wired the harness into my S-10.

Extra relays and an external gauge cluster (made up of digital gauges from Summit) were used.

You're looking at about a week (or more) of studying wiring diagrams, hooking up relays, and messing with your wiring harness. If you do it, you'll learn A LOT, but it's a big pain to mess with.

 

I think you'll need more than a battery charger to power the system. They usually don't put out many amps.
