bad coil cured 41s,great so now you have spark at the coil (the story in a shop)
next is spark at the spark plugs. all 4, must spark
and the timing light is next, to see that spark lands near 5 degrees BTDC, (5 to the left of 0 on the scale.
if way off the cam belt slipped is all do after 60k miles. easy.
now magically the car will start eveny with no fuel in the gas tank using instant start in a can , in fact can keep it running with my finger on the spray button
did it? the above steps proves 2 things, sparks really ok, end to end and the engine runs. 2 very important poofs
next you changed 2 relays, one below ecu is Main, other is fuel pump relay green socket, if you had looked, both are same part number exactly
if one buzzed key one swapped or not that tell you the fuel pump is shorted overloading all power to the ECU, (very very common)
this overload condition is covered in my pump page.
maybe wrong relay there.?
maybe one relay is now damage from pump overload. fuel pumps short, that one of there many bad acts.
and more, there will be lost of other problems. on any old car. (pump and FPR are 2)
so in the end 41s told the truth, coil primary signals dead.
cmp was ok, no code 42s (done right)
coil ways bad, but not just it, the relays bad.(or humptydumpied by the pump) humpty was pushed joke.
the pump is 4 amps. static, not 10 , the odd thing the wires are so bad the FI fuse dont blow.and the overload just cause Ecu POWER TO DROP AND FAil.
when the ecu fails,it reboots over and over madly, but cant so the relays chatter. vast sidekicks do that, when the pump is bad, or wires shorted to pump.
in a real shop we scope the pump wire
and go, like this, hay bob check out this pump it has bad commutator, see that huge 15 amp spike ever turn of the pump?
and gusess what if you stop car, key off and that segment lands on the wrong spot 4:1 odds or 6? the pump then overloads the ECU like clock work.
old fuel pumps do this. we test static current then with a scope for dynamic currents.
the wiring at the ECU sucks, its tiny and weak and can not function with any mad pumps. like that.
glad to see its running again,,, red head or now.
