right first off not new around and yes I know where and how to use the search feature. I have done so for the last week.

right now that, that's out of the way. I have 91 vert with a TII swap. Last week I could start the car no worries. Since then I have drained the old gas out of the tank, removed the tank, replaced the fuel pump, and put the tank back where it came from. Added about 5 gallons of fresh gas go to start and nothing.

All I was getting was a click from what seemed the front of the car. Let the searching begin. tried most of the ideas I found and still nothing. Battery is good as its less than a month old and used in my other FC. had the starter tested and it would spin but the gear wouldn't show itself about half the time. Ordered in a new one install it and same thing. :|

Now comes the bit that has me messed up. I pulled the B/R wire from the s terminal of the starter to check its voltage as I'm turning the key to start (it shows 8v). I notice the fuel pump has now come on. It only does this when the B/R wire is NOT hooked to the starter.

I have no interlock switch as when I got it had been removed and never needed to push the clutch in to start.
I have jumped the starter cut relay (B/G to B/L) and no change.
I have cleaned the grounds of any dirt greases oil whatever that may or may not have been on them.

I'm at a loss as to why my B/R wire to the starter shows 8v when its not hooked up and lets the fuel pump run. when it is hooked to the starter no fuel pump no start or anything.

somebody please unstupid me.

 

First off how did you go about removing the Interlock Switch? Did you jumper the two wires to the switch to bypass it?

When you jumpered the B/L to the B/G wire did you use the correct B/G wire as there are two to choose from. One B/G wire has constant voltage to it as supplied by the Antenna fuse. This would be the wrong B/G wire.

And in replacing the starter do you believe you connected it back up properly or are you completely certain this was the case.

 

As i've said I've read most of the searches that have to deal with the no start. hell read some on the interlock, the starter cut relays and so on. Many of those threads you've posted your knowledge on.

I bought the vert like it is now. It used to be 7dust's and he sold it to another who then appearantly went on to just mess the rest up. I never removed the interlock it was already gone. the car has started fine before hand without any issues. replace a fuel pump and now the thing won't even try.
the starter cut relay is fine as there is continuity between where the THICK B/G and THICK B/L wires plug to. and as stated before even with a jumper nothing changes. It's really doing my head in.

 

W/the starter solenoid wired up have you checked the Blue/Red wire of the Circuit Opening Relay w/key to start to see if it had voltage?

 

I shall check now if I can find the plug

edit: the L/R wire has no voltage with the key in start position

 

Yellow and Black w/5 wires located under the dash and just to the right of the steering wheel.

 

yep found that and checked with no voltage to it.

also checked that the Black/White wire from ignition has 12v all the way to the circuit opening relay

 

If that particular wire has voltage when the starter solenoid wire is unplugged then you need to focus on the starter and how it was wired when you replaced it.

 

nothing on the starter has changed. the new one is setup the same as the old. what I'm at a loss to explain is why the car just straight refuses to give any thought to starting when all I've done is replaced a fuel pump. is it possible anything back there (wiring wise) would have an effect on the ability for the starter to get its signal

 

If the power is cut when the solenoid is connected but doesn't when it isn't then it appears the starter is the problem. I guess you could try unplugging the fuel pump and seeing if the power is still cut w/the solenoid connected.

I guess it's possible that the amperage being delivered to the starter is insufficient but it shouldn't cause the voltage at the Blue/Red wire at the Circuit Opening Relay to be cut to zilch.

Make sure the connection between the starter and the Starter Cut Relay is solid as there is an intermediate connector involved.

 

something that tinges in the back of my head. is it possible at all that if the actual fuel pump wires were reversed to cause the lack of power? I'm 95% sure I wired it to the right posts as I kept double checking several times.

 

Doesn't the plug from the pump connect to the rear harness in only one manner?

 

well I put an RP fuel pump in. the RP pumps only have the posts instead of a nice lil connector. I may have to pull it out and just verify I did right for the billionth time lol
