Replacing 2.6L 4cyl. engine in a 94 Rodeo. We have dash lights, it turns over but doesn't start. There is "spark". Also, in wiring harness we have black/red wires (2) with juice, but don't know where they connect up to, there were 2 ground wires too -- wiring diagrams note that they are grounded but to where? (This is a rebuilt engine shipped from WI to AZ) We tested the wiring, fuses, fuse, etc with meters but can't find the problem. Suggestions? I would really like to get my car running again! Thanks!

Re: Replacing 94 Rodeo Engine--
Could be a failed crimp on a solder-less connector. Take it in to a
high end radio installer and explain it to them like you did here. If
your alarm is still functioning normally then its just a small wire off
the LED leads that's not completing a circuit.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

all engines can stall
with modern engines, the PCM does everything in its power, to prevent stalls .
the top cause is bad spark plugs or bad spark.
if then engine make odd sounds,?
all engines the run too slow shake and make odd sounds.
if the sound is metallic, (think of Micky mouse with tiny hammer hitting a tin bucket) that be bad sound.
no engine stated,but if the sounds are bad, id not ever try to start it. or bend valves in the head. (4cylinder)
if you ignored the cam belt, and not service it (new one)
at the proper time , the engine either stalls, no damage
or with 4cyl yes, damage.
both the 2.2L gas and 2.2l diesel engines are interference engines.
if you told me what engine you have, I can give 10x better advice.
do not run the 2.2L if the engine sounds BAD.
or you make it worse.
Please stop replacing parts it costs money!
Go get a timing light to see if you have spark if you do not it is a bad ignition module.
to check your fuel pump connect a fuel pressure guage to the engine fuel injector rail and turn over the engine the pressure should be: 40 to 60 psi.
an engine could run for 250k to 300k if you keep the oil and coolant changed regularly a rule of thumb is new fluids in an engine is always better than an old fluid. keeping spark plugs and fuel filter change and it helps keep carbon out of the top end.
This is straight from Haynes Repair Manual for 1989-1997 Isuzu Amigo/Rodeo/Honda Passport (book # 47017:
The 12 pin Assembly Line Data Link (ALDAL) terminal is located under the dash on the driver's side on 3.1L engines. To retrieve the trouble codes, connect a jumper wire to terminals A and B. It may be covered with a plastic cover. They suggest using a paper clip to jumper the two terminals-then turn ignition switch to ON position (NOT ENGINE START). Check engine light on dash will flash-one flash-a pause-then two short flashes-indicating code 12-diagnostic mode. After self checking-if there are any trouble codes-the light will flash proper codes using mentioned method.Note the flash code then call a shop with your info for what ails your Rodeo.
check for a small vacuum leak speciallythe lines going to the throtle have someone look at it while you seat onthe car , idle ,FOOT ON THE BRAKE ! a way to test for leaks if to spray a lil wd40 around the lines an listen if the idle gets better or worst, sometimes the reason the engine runs to rough or lean are vacumm lines that are slightly broken.
