ok, ill guess it cranks perfectly.
fact 1, there will be no fueling unless the ECU is happy.
- ECU thinks spark it good. (it has a pin a1 monitor)
- Spark is good.
- Throttle not stuck (TPS errors) wide open throttle.
if spark is good, IS IT? on all 4 ?
then try test fuel, if it runs for 3seconds on test fuel then the cam belt is not slipped, and there is spark.
if it does not run on tests fuel there is no spark or timed wrong, or the cam belt slipped. (very common on zero serviced cars)
if timing is still correct and runs on test fuel then we attack the ECU inputs. and outputs (the single injector)
this all sounds complex and is not
lets play that out.
- ah dizzy rotor turns , cam belt not snapped.
- ah, the spark is good but is way off time the belt slipped....
- The engine runs on test fuel, wow sounds snappy too.
- ok , i use a NOID light on INJECTOR pins 1and 2.
- the lamp is good, the fuel pressure , hark , is 0psi or 10. wrong
- the NOID fails, i then check TPS input voltage to the EDC
- its good, i find the tacho pin dead. OMG.
this year car the Distributor makes all spark the ECU does NOT.
but the ECU watches it like a hawk.
if pin A1 goes dead, ECU cuts fuel, ending crash and burn like seen on TV.
