Haven’t done a compression test yet because I sold my other engine and had to pull it and have been prepping the two rigs. Upon inspection when the body has been lifted a bit off the fram you can see the donor vehicle body and frame is in way better shape....so I’m now in the middle of a full swap. I will do the compression test today or tomorrow at the latest and post my results though before I pull the motor.
We buy used engine on pallet, we do compression test on the pallet using a stock manual trans bell+ starter motor.
that way no installing dead engines, for such and easy test.

would you spend a ton of cash on non related cures, for 180,180,180,30 PSI readings, no , you fix the engine first. what if piston was cracked, holed or ring lands all busted up..(from dead EGR and detonation) no need to put that in to any car, ever... needs fixing on the floor.(or machine shop )


Quick question my 1989 Sidekick JX ECU and motor and even fuel pump controls are different than the donor 1995 Geo Tracker....
the 89 is totally unique, in vast ways, I have page on that, called 89 differences
one is the fuel pump relay, i married in inside the main, relay (and is expensive and hard to test ) and if warm outside, the 3 second key PRIME is HOT THERE
it must be cranked to get fuel pressure. very unique, for sure.





Am I able to plug and play my 1989 ecu and engine into the 1995 geo wiring harnesses and body? 95 8valve? 95 came with 2 different engine, 8v and 16v.
NO, the 89 has no spark controls at all , the 95 generates all spark.
yes if you move the everything, that includes the distributor but is not the gear on the distributors hugely different, id be all over that first.
be sure to look at the 88/98 head , rear distrib house and cam gear then on any 91-95 (usa years) engines.

Im aware the injector wires and the IAC are Flip flopped. (ah at he jack plug, at first did not know what this means, do no) and is ISC.
IAC is thermal only, in the base of the TB.
some books call them both IAC and is wrong. The need 2 diffr. names..

The 95 injector has different part number than the 89/90 , not sure why but is an issue.


And that the fuel pump on my 89 only activated key on unless cold outside. (ok i see you know that already)
But other than that what other differences or issues would I have if I didn’t swap over the wires?
one more the ISC in the 88/9 coil ohms is 2 times different than the 91+, so you mix them with different wrong ECU you burn up the ECu that wants 2x ohms coil, do not connect 89 ISC to 95 ECU or boom, burn up the driver in the ECU. 2x more current and boom,

Just a quick update, been busy changing career paths, had a few tests/certificates to get out of the way. Now I’m back at it and noticed my starter is junk...sigh

I have the battery hooked directly up to the starter and not really getting anything more than clicks when I complete the circuit with a wire or screwdriver. Am I doing anything wrong or am I correct and just have a junk starter? I had problems once and a blue moon with it as well.
