90 is unique of all trackers, 89/90 . 1.6L TBI motor.
90 is 1.6L EFI , some 89s are CARB 1.3L in USA> or canada.
90, has a stand alone DIZZy. the dizzy makes spark with the ECU , sitting on the work bench. dig? dizzy + coil.
4WD? if yes, it has a dash tachometer. and shows 0.3 RPM (.3 times 1000 is equal to 300) RPM. cranking. (below 1 mark) does it,?
so when the engine dies always check spark. first. in all 5 places, if 1 is dead. 4 spark plugs, and coil.
if spark is good, the ECu does watch(tacho line) it like a hawk, if the ECU sees this spark as dead (even when perfect) the ECU will in fact cut fuel 100%
#1 cause lost or loss suppressor module ,
if the ECu cuts fuel , you look down the air horn of the throttle body, oops it stopped injecting (no tools (save a spanner wrench) and you can watch any TBI inject, 89-95.
it can also die for many reasons, ( i find the no start reason.)
1: lost spark
2: dead Tachometer. (dizzy makes this signal, and must, if not , fuel stops)
3: lost 12v power to ECU, or coil or DIZZY (lost ignition, power, or bad connectors)
4: flooding, are spark tips soaked in fuel? flooding?
5: or dry spark tips?
if dry does test fuel work? (do only if spark is good.)
if dry , use the NIOD lamp to see if Injections stop. if NOID passes, and does not spray cranking then fuel pressure is zero.
good luck to you.
my guess. is the bump kills electric power to ECU, DIZZy or fuel pump.???????
