Ok..Running a JRSC on a LS/VTEC stock fuel system except a Walbro 255 pump. My question is my car will not run. i cracked the nut open on my fuel filter and it had what i think to be way more pressure that its suppose to. pulled the brand new plugs and there dry. So what do you guys think it could be?? just throw some ideas at me! Thanks boys

 

So your car has never run?

When did it stop running?

 

I hope you dont have the stock plugs in there ... so you cracked the nut and your leaking fuel? Was the walbro installed incorrectly? Can you here the pump prime when you turn the key?

 

The car just died last Wednesday and the walbro has been in there for bout 4 months

 

Im also using a one step colder plug which Jackson recommended

 

Anyone have any ideas???

 

You think it's the fuel pressure why?

There are any number of things that could cause your car not to run.

How does it not run? It doesn't even turn over? or it stumbles and dies?

You're going to have to give us a lot more background info if you want help.

 

Its does spin over and want to fire but doesn't ! tested the injector wires they check out. could it be the ecu?

 

do you have good spark?

 

Yeah!

 

You know this because?

 

we tested the dizzy also and it wwas getting spark from there

 

no CEL?

 

No im running a P28 sorry i think i left that out

 

So you haven't changed anything, it just randomly stopped starting correctly?

 

installed a Apex WS exhaust

P28s like to die on you. I had to repair mine. If your pump isn't priming, it's either your P28 (very common problem) or your main relay (very common problem).

 

It must, considering he thinks there is *too much* fuel pressure for some random reason.

Yeah, what the deuce is he talking about?


What do you mean too much pressure? What exactly were you doing with the filter?

 

When you relaese pressure from the filter some should spray correct? Well mine burst out quite a bit more than i think it should have. and i can hear the pump.

 

While that sounds like a neato shadetree mechanic method of measuring fuel pressure, it's not very scientific.

 

so maybe but... what would you say you think it is??

 

I dunno. You've given us nothing to go on.

engine needs a few things:

1) fuel
2) air
3) spark (at the right time)

one of those areas has a problem.

 

have you heard of many problems with p28 ecu? fuel system is basically stock except walbro 255lp pump. no ignition upgrades either

 

It's chipped, right?
