Wont crank potential fuel pump issues - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a s14 swapped with a blacktop sr20det. On Sunday the dome light was left on and yesterday afternoon when I went to crank it the battery was dead, so I pushed it out of the garage to jump it off my other car and it wont crank, it turns over but wont crank but a couple of times it acts like it may crank. I have a walbro 255 and I have checked the fuse and even replaced it with a 20amp, I think it might be the fuel pump relay but I am not sure. ANyone have issues like this before and where is the fuel pump relay located?

Thanks for any help that might be given!

Crank = starter turns engine. Will the starter turn the engine or not? Is it cranking but not starting?

If it's a weak crank I'd check the battery connection and starter.

Okay so I have tested many things to try and narrow my problem down.

Fuel pump is working fine and the car is giving fuel.
All fuses have been checked and double checked with a check light on each end of the fuse.
Plugs are definitely getting spark.
Started is definitely working.

It doesn't make any sense why the car would crank perfectly before the battery died and now it won't crack over and the battery is charged.
