I need help people, I have a 93 DA with a dead b18. so what I did I placed my b17a1 motor in it when I finished putting the motor I used the b18 wiring harness which has no vtec solenid sensor connection. Now what happened is the car crank and I had a test drive it ran good but it died on me and it won't crank no more and I just put some gas in it. So as I was checking on it there was no pressure to pump gas at all. I was thinking if it is my fuel pump relay or fuel pump or something... is this something about that vtec solenoid connection? what you guys think that I should do?


-when I try to start it it cranks but it just won't start.

 

what ecu do you have?

 

I think you should buy yourself a voltmeter or a magic 8 ball. We can't tell you what's wrong with it, we are not sidekicks. You have to find out if there is power at the pump, if not you have to trace it and see where it's cut off.

 

yep yep.

See if you got power at the fuel pump plug and if not, its probably the main relay. If you do have voltage, its probably the fuel pump.. If your not getting fuel press. all of a sudden then you've only got a certain number of things that it could be.

And no, vtec solenoid not being hooked up would not cause it not to start. Look into buying a p61 ECU and a obd1 vtec harness though for when your done sorting the fuel issue out.

 

Oh ok thanks people.. I will try to do that then..

 

Guys I changed my relay and took my fuel tank out and check my fuel pump is fine nothinh wrong wiyh it.. what you think might be a cause for not having pressure? I'm thinking to check fuel injectors or fuel rail.. what you guys think I should check?

 

check if you have pressure at the rail...

if you do, check the injectors

also i didnt read much, do you have spark?

 

There is no pressure at all I have a gauge at my fuel filter it shows no pressure. I changed filter and relay checked pump it works I might go check rail and sparks. Thanks

 

well no need to find spark yet, you might not have a problem with it

it is possible to have water in the line and it froze, get it inside

also, jsut cuz you hear the relay clicking doesnt mean the fuel pump is ok...

these are all just ideas

 

I actually took the pump off and tested it. You where saying bout water and it froze can you explain more bout that? You guys are really good help.. thanks a lot!

 

not much to really explain, water could have gotten in the line and froze due to the weather (its cold over here i dunno about you) if it is by you, push it in the garage and let it warm up and diagnose then

 

oh i see.. its not that cold here but im going to check it out.. for now im going to check fuel rail or injectors.. thanks
