On a 2nd gen the pump does not flow until the car is cranked and the AFM senses airflow. I would immagine a F.I. 1st gen bieng very similar.

[quote name='Shane.Trammell' date='Aug 18 2005, 10:11 PM']hey does anyone have any idea why we wouldnt be getting power at the fuel pump? it was running 2 days ago so i guess it had power then. pretty much the whole engine harness is not being used now, the o2 sensor is plugged in but i think thats all. the water temp connector is not connected. all of the other parts aof the harness are not connected.

the battery is connected and the pump is actually getting about .5 volt, and it runs, but it doesnt sound good and wont get any pressure.



do you guys think it could have something to do with the AFM not being plugged in?

What about the yellow connector that has four wires in it under the windshield washer reservior. Did you unplug that one? It normally provides power to the ECU and injectors. Did you disconnect any fusible links? Check the engine fuse (20 amp) in the car. It also powers the pump. That wire under the car is probably the exhaust overheat sensor or one of the transmission swtches (reverse, neutral, or 5th gear). Make sure the inlet and outlet lines are in the correct spot and make sure the polarity is right on the pump.



Kent

are you saying that we need to unplug the yellow one under the washer, or just make sure its plugged in?

gsl-se ecu doesnt turn the fuel pump on unless it sees a tach/rpm signal from the trailing ignitor

thats good to know, that solves all of the problems. except we arent totally sure that the fuel filter is whats causing the fuel blockage.



j9, do you know positively that the stock gslse filter will not flow with this 6psi pump? a lot of people are saying yes and a lot are saying no, but no one says they actually know from experience

Make sure that the yellow connector is connected. j9: I am pretty sure that is true on the 12A cars, but the GSL-SE uses the switch in the AFM to do that. The fuel pump is energized with either



-key 'on' and AFM switch activated

or

-key in the cranking position.



If there is no signal from the trailing, the injectors won't fire, though.



I believe Paradox on the club was using the SE filter with a Holley carb. I will ask him, though. I is possible that it may be too restrictive for a carb pump, but that should matter for low flow/starting. It could possibly starve fuel at high rpm/load, though.

oh yeah forgot about that shutoff switch https://www.nopistons.com/forums/pub...DIR#>/wink.png

hey guys what do we need to do with the timing advance? the kit says it wont be used, and the vacuum lines arent connected to anything right now bc the rats nest is gone. do we need to secure the distributor or anything?
