Hey all,

I might have a relay problem, but may not, this seems like the best thread to continue the discussion!

Drove the car one weekend, went to go drive it the next weekend and it never started

Rundown:
- Crank but no start
- No CEL with key
- NO RPM with cranking
- Fuel smell after cranking without spark plugs, but no priming from the pump

Progress:
- Replaced/Regapped CKS(Crank Position Sensor)
- Replaced 10A Room fuse
- Replaced B5B4 INJ fuse
- I've found that if I clamp the right side of the old relay (pictured below) to make contact with the rest of the relay I get a click/hum in the bay
- When I do this, I get the CEL
- Still no RPM on crank
- With the new relay, I get nothing (no hum/click, no CEL, no crank)

Did I get another bad relay? Or is this a deeper problem?
