2.9 project almost done and then...

[Roowen]

I have an 87 Ranger w/ a bad engine.So I got an 86 BII to sacrifice for it. I swapped out the engines and am close to finished. I had a few small problems but solved them. The truck will start and idle but has no or little throttle. I noticed @ night the headers glowing red and thought blocked cat.
Well, I eliminated that problem and it seems to have cleared up the blockage and yet still no throttle. So I hooked up a code reader and got 2 codes. Evap voltage too low(which shouldn't matter) and tps sensor out of range. So I switched out the tps with the BII's, to no avail. Could the timing be off a tooth, or could the high pressure fuel pump be not working? I have 40 p.s.i. at the rail, which should be good. I have been non stop on this and need a fresh point of view,or some guys like us who know Rangers.
Com on guys this is probably looking me in the puss and I can't see it! Help, please.

Bad TFI? Plugged fuel filter? Computer wiring all good?

Which computer did you use? It sounds kinda dumb, but try using the BII computer instead of your rangers, im assuming you didnt swap them. It happened to us, put an 88 BII motor in a 89 BII and it ran like crap with no power till we swapped the 88 computer in. Something to try.

I switched out parts one at a time replacing w/ original once I knew they were good.(TFI,fuel pressure regulator,distributor,coil,etc..)But I kept the cpu from the Ranger.
