No fuel injectors, spark plugs, or fuel pump
Nothing Is running, what could be causing these problems to happen all at once?
-I give the fuel pump 12v and the injectors dont even fire when I crank it over.
-KOEO the fuel pump doesnt even prime
-Spark plugs/distributor also arnt functioning. Swapped Distributor out with known good part
-Have tried 2 seperate obd1 ecu's one mapped and one stock Ls(same results for both)
If you have any Ideas please, let me know what could be causing this
thanks.

I swapped it out with a known good pr4
just to get it started, I kno it wouldnt run the 1000cc injectors but it would fire over. and cure most symptoms if it were the case.

Re: No fuel injectors, spark plugs, or fuel pump (B*CRUZ)
there is no 80, but all fuses are getting 12.22v which is more than enough to start.
here is a small switch I had found under the dash next to the CEL reset switch.
the ground in blue was just bolted to a 10mm under the clutch.
Red stopped at a small butt connector type deal next to the gas pedal
The yellow I could not figure out where this one had gone to.

Re: (LordAphotic)
I cant hear fuel pump priming...
I hook jumper to it, fill the rail (which has a fuel pressure gauge)
Crank it over w/pump off and fuel pressure stays the same, which means injectors arnt firing.
and I have hooked a spark tester up to the wires, grounded a known good plug and check that way...

Re: (JDMB20TDA)
Key to ACC position, No click at relay
Key to On position, No click at relay {but if cycled between On & Start it will click}
Check engine light never turns off and throws no codes.
will swap relay out with known good part later this evening.
hope this is the fix, when trning key to start position is it normal to hear a small clicking near Ecu {pass side floor}?

Re: (JDMB20TDA)
it sounds stupid but release the gas cap if you haven't driven the car for awhile then you will have built up pressure in the lines which will not allow for your fuel to reach the injectors. it happened to me twice already the first time i changed the fuel relay,.ecu, and changed the filter still didn't work. finally a mechanic told me to try this and it started right up. second time same thing car was sitting for like 5 days, same thing changed relay nothing, ecu nothing, gas cap and it started like nothing ever happened.

Re: (GSR-TRBO-DA)
The fuel pump isnt priming either, and I can see the Fuel pressure gauge rise up when I physically jump 12v from the bat. to the fuel pump.

Re: (JDMB20TDA)
yeah but did you try what i told you? how do you know you have fire? pull a plug and connect it to the ignition wire like it would be if it was still in the cylinder head then have someone crank it if it shocks you or you see spark then you have spark. it is not that bad of a shock but it does shock you. but atleast you will know if you have spark then get back to me.
