Alright I'll do my best to list off what I have done just as much as I have tried to search and source out this problem

94 civic
-lsV was pulled and running
-new distributor
- new ecu with chip (tested in my daily del sol)
- tested main relay in daily along with used the current working one in my daily
- all the fuses check out to be working
- cranks but no FP or spark (but power at dizzy)
-power at dizzy
-brand new rywire engine harness
-fuel pump is an inline walbro fuel pump (stand alone power and ground setup)
-stock fuel pump ground is grounded
-triple checked all my grounds and connectors for my ground(all brand new)

Does the stock fuel pump power wire need to see a signal?
And I missing some sort of ground in order for my setup to work properly?

I have tried multiple things that I have read with forums and I can't seem to find the culprit. Any help would be greatly appreciated! Thanks h-t

 

Any takers or ideas welcome please!!

 

This may have gotten better response in the 92-00 civic/del sol forum.

I don't have the power to move the thread there, maybe another mod will be kind enough.

 

I'd appreciate that, wasn't to sure of placement

 

Anyone?! Please

 

Update: found no power at the fuel pump power suply wire..
Going to attempt to address this problem after work

 

Jumped #1 & #7 on main relay pump stays running
Jumped #5 & #7 on main relay dizzy and iac clicked

Any suggestions?

 

Pump doesn't run on this^ test? If so, voltage test 15A fuse 24. Click the Test Fuses link in my signature.

 

Correct on test 5&7 no pump power

 

That's the problem.

 

12.8 V. On fuse 24

 

Both tabs?

 

Correct both tabs

 

Convince me you know the location of fuse 24.

In the meantime, do this test:

Turn key to ON(II).

Unplug main relay.

Measure voltage to body ground at terminal 5 (Blk/Yel wire) in the unplugged connector.

What is the reading?

 

16V. it's on the charger at moment so I'd assume that being the high reading

 

Your collective tests don't make sense. If terminal 5 has voltage, then the 5 to 7 jump test SHOULD make the pump run.

 

Hey on(ll) for the 5&7 test?

 

YES

 

Now it's just dead no click, no power to fuel pump

 

Sorry fuse popped accidentally grounded power.
There's a clicking noise in the bay and the cel flashes when I jump 5&7

 

Jump 1 to 7. What happens?

 

Fuel pump runs when 1&7 are jumped

 

1&7 jumped fuel pump turns on is good, 5&7 jump with the ignition switch on (II) the fuel pump should be on also assuming there is voltage coming in at pin 5 on the main relay connector. if you do NOt have power on pin 5 at the main relay connector then you have a short somewhere or a bad/wrong ignition switch on it. Without pin 5 not triggering your fuel pump on when 5&7 jump then it would not trigger your ecu to turn on, when the ecu is not on then you wont get any spark and fuel pump signal.

Post clear pictures showing you measuring voltage at pin 5 in the main relay plug.
