Fuel pump does not prime = one of the following reasons
1. Bank angle sensor (located between the headlights )
2. Fuel pump relay
3. Kill switch issue
Have you worked on the bike lately doing upgrades , maintenance
etc etc



If it doesn't challange you it won't change you

the bike was wrecked. I tried bypassing the bas, but no luck, If I put direct 12v to the pump, it primes, other than that, it wont prime, and no spark

Have you checked the relay? Have you tried all 4 plugs or just one? You know you need to hold the plug close to a head bolt or something like that (hold the plug wire with some pliers or something) right?

I just tried one, Im pretty sure the rest of them wont have spark, because it will still run on 2-3 cylinders. and yes, I held it close to the block

My next suggestion would be to check peak voltage out of the ign coils and trace it back from there. Do you have a wiring diagram?

which means no service manual either. There are numerous things that it can be and I have found that with electrical diag it's easiest to start at the problem and work your way backwards until you run into the cause. Unfortunatly with no service manual we don't have the proper numbers for running these tests. I can look up your service manual at work tomorrow and fax you some pages that will help you out, if you want.

It seems to me you are getting your thoughts into to many directions
not your fault . Here is what i suggest deal with one issue at a time
1. No spark check the coils get that resolved and attack the next
issue
2.Fuel pump Bypass the Bank Angel Sensor
etc etc all of us here will keep you going man and eventually will get the bike going Amen

yea, but theres no spark AND the fuel pump doesnt prime...Im guessing one has to be related to the other in some way? a fuse(checked all the fueses), or a relay(I dunno hot to check the relays)

Ok then check the fuel pump relay may be its a faulty relay
may be the pump is not getting power if the relay is ok
check the kill switch wiring

Fuel pump runs with 12 Volts - bypassed BAS= not the problem
Fuel pump relay (very common issue) - ?
Kill switch - def possible, i would go with the relay first.
Other options - don't know without wiring diagram

Ign
No spark in one plug - good plug?
Sure that it's all plugs or it would run on 2 or 3 cyl - not without fuel
Peak voltage to plug - not sure
No voltage to plug - voltage to coil?
etc. etc

Proops to you man for thinking out loud we all learn form one another
which is fantastic and hopefully all this will lead into streetslide getting
the problems resolved

Sure man even though you stated you are new to this you know a lot
more than others that have been here for a while and this by itself is
an accomplishment in my book :icon_supeand u are sharing your knowledge
even though its limited in your beliefs keep it up man your knowledge will
expand just give it time

be carefull because not all of those relays are the same resistance. Do you have a multimeter? one simple way of checking the relay is to check for voltage after the relay at the fuel pump. no voltage= bad relay (most likely). you would probably want to check voltage into the relay as well to make sure its not the kill switch. Same goes for the fuel pump as the ign problem. start at the fuel pump and work backwards.

voltage at fuel pump when key is turned on - no
voltage on the other side of the relay when key is turned on - yes
=bad relay

sounds like the right amount of voltage at the relay. no service manual so can't be sure but def sounds right. That means it's not the start/stop switch because the power goes all the way through to the relay. No power at fuel pump means bad relay. replace it and that should fix your fuel pump issue.

is there a way to bypass/jump the relay temporarily to see if it is indeed the relay before I go out and buy one?

Well, there is voltage before the relay and you already applied 12V to the fuel pump so we know it's not the fuel pump and the power stops at the relay. I'm pretty sure it's the relay, should be a pretty cheap fix though. If you have a friend with the same bike you can take out his relay and put it in your bike. That's one for sure way to know it's the relay otherwise, cross your fingers and buy a new relay. Good luck
