99 gst no spark no fuel

[Ozyeclipse]

Getting strait to the point
99 eclipse gst
Previous owner said it just died when running
Symptoms
_no start
-no fuel
-no spark
-blowing ignition fuse 30amp(pink)

Solutions tried
-rewired ecu with a relay for fuel delivery and spark

-New ecu(didn't work).

-New cas sensor 99..

The previous owner took it to a shop where they diagnosed the computer to be faulty
So they redid the rewire.

I do have another ecu but its from
a 98 spyder gst could I swap those computers and get rid of the relay

Also what are other posible solutions I could try

Sounds like a wiring mess, try the ecu, bad fuel pump, wiring relay, fuses, swap ecu and see what happens, how about the coil pack, or ignition transistor?

Fuel pumps good works when I wire it directly
Yeah its a mess I tried a new ecu and got rid of the relay but didn't work

I have another 98 spyder gst ecu r they the same as a 99 gst

Should be in that year but im not 100 percent sure.

you could have crank walk and it damaged the crank sensor. i have the same problem, no spark, no injector pulse and no fuel pump. i pulled the timing cover and the crank sensor was thrashed from the hall effect plate hitting the sensor. i went trough 3 hours of diag, checking the efi (main) relay, power to the ecm, ingition switch ect ect ect.
this is just a possibility.

Well its defenetly not crank walk this is a revise block from the 99 very uncommon on these years
I've had like 6 from 95-99 and only one of them walked because I ran it on low oil for 2 weeks other than that 7 bolts have held pretty strong for me
6 bolts ate just bullet proof I know I had 4 or 5 of em
Although u gave me a great idea that my crank sensor might be bad
Could be messing with my ecu to not get spark my fuel pumps defenetly working cus I have fuel pressure now just my injectors aren't opening

I had the same issue on my 97 but much bigger now a new crank sensor did the job for fuel and spark
