the car does not want to start....fuel line is not kinked, has full tank of gas but it keeps on cutting off, why? he just got his p28 re-chipped but still had the problem before rechipping it...it will turn on from time to time but when you take it for a drive it starts bogging and hesitating like its gonna turn off....at one point while it was in neutral, he had the gas pushed in like at 2 grand and held it there but then it started to rev all crazy, up and down then shortly cut off....i really doubt its the fuel filter but am going to change it anyways....i was kind of wondering what are the chances of the fuel pump going bad? is there anyway to check it? if it is the fuel pump we will be replacing it with a walboro 255 pump....any help would be greatly appreciated....thanks, Sal

 

anyone?

 

one of my buddies that we did an ls/vtec on had the same problem and it was the wire harness so you might want to try that.

 

kind of an obvious Q, but is it throwing any codes?

 

hey jweller its actually on greenlions accord who just sold you the f23 head...anyways no its not throwing any codes with the rechipped p28.....still leaning towards fuel pump

 

yeah I kind of figured it was you guys

I'd say its definately not the fuel filter. the guy at Honda told me that the fuel filter is basically a lifetime part. you should never have to replace it unless somebody sugars your tank or something like that.

 

fuel filter was just a safe side thing, anyways so what are the chances of it being the fuel pump....after all he did change to using 93 octane everyday cuz of the h22....thanks, Sal

 

I'd be suspicious of any mechanical part failing after installing a rechipped ECU....

I'm not saying it couldn't be, but thats just my general feeling. It sucks to throw parts at a problem, although a walbro pump is a good part to throw at a car

I'd say check the pressure at the fuel rail when it's bogging and not starting. A bad pump would leave you with low pressure at the rail.

 

has he tested for voltage at the fuel pump?

 

havent did the volt test but will do before we going checking teh fuel pressure....anymore info, keep it coming.....thanks, Sal

 

Is the car missing when you rev it.. It could be a distributor problem. Timing could be off, bad spark plugs, wires, ignitor could be bad, alternator. There are many things that can cause what you are describing.. If your pump was bad then the car would buck..

 

well it is bucking....wires and plugs are new, distributor was recently changed from one of the best performance shops here so that shouldnt be a problem....not sure about the ignitor or timing??? thanks, Sal
