89 starting issue
#4
first off, if the engine was good, and the spark was good, test fuel would work, ( i bet test fuel fails)
(i do test fuel tests, with fuel pump relay (green socket) pulled,

ok this is a major swap, not just , ran good for 24 year, then died ,yesterday car... ok ,
the 89 EFI is totally different than any 93. but not yours...
a strobe light is not a real test. its will flash prefect with weak spark. only using a real spark plug , proves, spark is right.
spark plugs new, set to .028" and not set to the useless, .045' as set by NGK in the NGK factory? and stock J plugs, not $20 surface fire plugs?
the 89 dont care what body but the harness does. the speedo cluster too, and its harness will short out the spark, feed back.
you need to be more specific on what was swapped, The 93 speedo wires up 2 things quite different, the VSS and the Tacho.
do not mix harnesses, but do ask why , and Ill show you.


if i had this car id....
1: check compression, 155psi is about right for cold motor. (not running) if not , then the belt was timed wrong.
the cam most be timed, at #4 firing and made sure that it is timed correctly and compression is good. then...
and lash set to spec. if not , the valves burn up.

2: then time the dizzy (after making sure the dizzy rotor is not a china rotor that fits on 3 ways, use a Bosch rotor for perfect 1 way fit.)
with the valve cover off during lash set, you turn the crank to TDC 0 mark, is the lash at #1 lifters loose, if not, turn the crank CW 360 degrees.
now the lash are loose on #1 valves. this is true #! firing. (if never loose, then lash was never set right.)
then look at rotor in dizzy. is at at 11pm. ? see photos here.

if , not at 11pm, then remove the dizzy and drop it back so it is, there are 13 teeth on the gear. there.
I then time it with strobe. cranking. near zero.
it will now start on test fuel. (for sure)

now try to get injection. working,

if compression is low check lash, if lash good do my sneak-a-peak test. (proves belt is correctly timed)

it will run, soon.
cheers.

It is the original 1.6 from the 1989. All plug wires pulsing when cranking with timing light attached.
Definitely fuel at the TB throat but plugs appear completely dry. I swapped an entire running 1989 in to a clean 1993 body.
All wiring, ECM etc. ( all ?, really?)
The 89 had a bad head gasket when I got it ,had the head redone and reinstalled while out of the vehicle.
I am at a loss, but will keep checking things with your diagnostic pages. It will run, I promise, we can do this 1 step at a time, and will run.
If the igniter were bad would I still have the timing light strobing on each plug wire while cranking ?

the 89 ignitors are known problematic, they like to do things a 91 would never ever do.
in fact, the 91 dizzy , usually never ever fails. (tuned up)
the 89. has 2 parts. the VR device and the ignitor,
the VR gap can be wrong and spark is weak or random
the ignitor likes to fail or ,go bad hot. then work cold.
you need to test spark quality with a real, spark plug. the timing light is for timing. and new timing lights flash great with weak spark.

and the rotor spins CW.

the below assumes the owner knows, #1 is the front cylinder, F1,2,3,4R
this #1 below , i like to all 11am location.

how to test for spark
use a real fresh new (any brand or heat range , spark plug) gapped to .028"' this car does not HAVE HEI (high energy Ignition,)

http://www.fixkick.com/IGN_timing/how_to...spark.html

check it in all 4 places and at the coil,. the spark must be robust. blue-white flash, not weak, orange and tiny.
like this video shows.

best is to start with a fresh set of Bosch Mag wires. (cap and rotor ) no china "noname " crap ignition parts allowed.
