FI troubles....Questions!

Can I test a 1989-90 5 speed ECM on a 1989-90 Automatic Tracker/Kick?
I have two 1989 ECM's and they both have the same problem:
No 12v or pulse to the injector.
Both of these are from woking trucks when I parted them out...

Is the Ford type pump enough to supply the FI?
Does the ECM recognize if the pump does not have enough pressure?
I keep getting code 14 which is the Engine Coolant Temperature sensor problem, but when I check the sensor it gives me a reading of 2.2K cold and 700 hot...is this normal?

Other questions to follow!

LOL! I thought I was the only one that had problems like those.
Sorry can't help you much though.

[/ QUOTE ] Danny, do you have spark? The injector is fired by pulses sensed by the ECM from the crank angle sensor. If you have no spark, the CAS or its wiring may be suspect.But the auto or manual ECM should still run the engine. </font><blockquote><font class="small">In reply to:</font><hr />

[/ QUOTE ] I don't know what the output pressure of the ford pump is but the ecm would only "know" of a low pressure by seeing a lean count off the O2 sensor. It doesn't have a fuel pressure sensor per-se. </font><blockquote><font class="small">In reply to:</font><hr />

[/ QUOTE ] That sounds to be the correct parameters for the CTS, Wildweasel has my FSM right now so I can't quote exact numbers. [img]images/graemlins/frown.gif[/img]

Re: FI troubles....Questions!

the Ford pump is VERY sensitive it filter restrictions. When I first did mine I chased the problem for a week and it turned out to be a filter. It seemed OK, it was an after market one made for carbs (low flow) and was brand new.

Re: FI troubles....Questions!

Ok here we go!
I called up the good folks at ECM-ToGo and they were very helpful. I was able to test the 3 ECM's I have here on my 89 auto Tracker. ALL OF THEM ARE GOOD!!!
SOOOOOOOOoooooooooooo that leaves me with checking the wiring or the sensors. That's a refief cause them ECM's aren't CHEAP!
Back at er tomorrow and I'm SURE i'll get it running..... [img]images/graemlins/grin.gif[/img]
