change the fuel pump?

[tsoccer3299]

ok so my car for awhile now had trouble starting when it was cold, now it seems to happen every once in awhile when it is a little warm too. It just cranks over but wont fire up. I'm kinda limited in what I can do since I'm here at college. I've changed the ect sensor, fuel filter, cleaned the iat, iac, and maf sensors and no luck. When I put the key in the on position I can hear the fuel pump prime like normal, sometimes i will sit there and prime it quite a few times and it seems like this makes a difference. I know I should buy a fuel pressure gauge but if I buy that and the fuel pump is bad then thats one more thing a poor college student cant afford. Thinking about just buying a 255lph pump and seeing if that works cause eventually i will need it if i go hci or something else. What do you guys think? This one on ebay any good? or just get a walbro?

I got my Walbro on ebay from 'mrfuelpump' for $94 shipped. Good luck with it; definately sounds like the pump if priming it repeatedly helps.

maybe worth just getting this 155lph pump? what kinda power would a 155 support

Another vote for a Walbro pump. The size is up to you. It would depend upon what kind of mods and power you plan to make in the future.

Good luck.

i have a walbro 255lph and i got it for $105 shipped. Got it from jdsperformance.com

yeah id get the walbro but i just found that 155lph one on ebay in the link i posted and its real cheap. what do you guys think of it?

I'd still say you'd be better off with a Walbro for $30 more than your first selection. With Walbro you know what you are getting. You may be taking a chance with the others.

255 is way 2 big for your stock motor, 190 would be the limit. even with heads and a cam the 190 would be fine.

yeah i realize it is way overkill but on our cars dosent it not matter since we have a return fuel line? eventually i would like to get a supercharger

Correct. The return style fuel system passes the extra fuel back to the tank. There are arguable side effects from a too large of a pump (fuel heating, etc), but they are not worth considering. Especially considering your future plans.

Good luck.

+1 for jdsperformance.com I popped in a 255lph a few weeks back. Car runs just fine go for it it won't hurt anything.

on jdsperformance they have a high pressure 255lph and a regular 255. whats the difference? guessing i dont need the high pressure one maybe?

The HP version does not have as much pressure drop off at around 60-70 PSI that the non-HP version does. The HP pump is nice for blower, FMU, etc applications.
