GSR HEAD / B20 bottom end / T3T4... DSM injectors...resistor pack wired in CORECTLY...
STOCK Fuel Pump...

Since the motor was dropped the car was running good for about 4 months, went to Church Auto down in Long Beach for Dyno Tuning about 3 weeks ago... Maxed out HP @ 200 whp 8 psi because the fuel pump would not keep up...

3 days ago the car DIED on the freeway... progressively lost power over about 10 miles until it just shut down...

after i had the car towed home, i was assuming that the issue was caused from a dead Fuel Pump... but im not sure... i have also heard that it might be distributer issues as well, but im not too sure how true that is...

i then pulled the fuel rail off and had someone turn the key... NO FUEL SPRAY... not a drop...what might be causing this?

Well, the main relay powers the fuel pump, but only for about 2 seconds when the key is first turned to run. (The amount of time the CEL is on. After that, the ECU looks for confirmation the engine is running before energizing the pump again.)

If the pump doesn't run during the time the key is first turned, either the pump is dead or not getting power from the relay.

 

makes perfect sence... my main relay went out about 4 months ago or so... the car would start and stay on for about 1-2 secs then die.... NOW the car wont start at all... and there is NO fuel comming out of injectors... SOOOOOoooo... since the car will not start WHAT-SO-EVER... might that sound more like a pump issue rather then a MR issue?
