Speed sensor

[Bruce Plecan]

If it wasn't needed, why did gm even bother?.
If you do everything right, then there are no errors.
Again, I'm not impressed with Howell, amongst others.
I'll take reading the archives here, and seeing what the guys who truely
know code have to say about things.
It's alot easier to do it right once, then rehash twice.
Just consider your 4.3 as a 5.7 with 2 cylinders missing, all the sensors
are the same, and your probably running a 1227747 ecm, right?.
As far as efi swapping it's a matter of getting a good wiring diagram and
getting
real comfortable, and go wire by wire.
Mechanically don't overlook, or minimize the importantance of <s  for
offset, pinion..

| Hi everyone.A while back i was asking questions about fuel injection for
| a 4.3,being swapped into a Toyota.Well,i have now found a newer engine
| to use.I picked up a 91 4.3 throttle body engine,from a Safari van.
|
| So now i need a wiring harness.I contacted Howell and Painless.Howell
| says a speed sensor is not required for the engine to run smoothly.Matt
| at Howell says that it will only affect the EGR,and not the IAC.
| Painless says that the engine will always be stalling on deceleration.
|
| My question is this.How will the IAC motor reset its position if it
| doesn't have a speed sensor input?It is my understanding that this
| happens when the vehicle reaches 30 MPH.
|
| There is no smog testing where i live.
|
| So,do i need a speed sensor or not?
|
| Anyone know of any good websites dealing with 4.3 swaps and such?
|
| Thanks,
