I was wondering if it was possible to have to much fuel pressure? would this cause my car not to start?

well, yes its possible to have too much fuel pressure

However this is extremely unlikely if you have a stock pump, or even a performance pump for that matter.........

your car won't start - more than likely - because its flooded.....

Whats the info on the car and what is actually happening with it?

I notice that it floods more frequently(like every thime I try to start it). I notice that I have fuel dripping out of my exhaust. I thought it was an ignition problem but I have plenty of spark now(replaced lead ignitor). last year it started but wouldn't idle,it would surge, now it won't start at all. I do have an upgraded fuel pump(walbro 255lph). I was told this would work with my stock set up. I also replaced maf.


list of things I have checked:

pressure sensor
thermo sensor
intake temp sensor(both)
t.p.s.
compression
b.a.c.
b.a.c. control valve

things I have replaced:

spark plugs(new)
wires(new)
leading ignitor w/ coil
m.a.f
throttle body(not inc. tps)
crank angle sensor
fuel pump(walbro 255lph)
vaccum lines(all)

one more thing it is a 87 non-turbo base model any help will be greatly apreciated, since I have been battleing this car for more than a year now

Have you even checked the compression?or did you just go replacing throttle bodies and crank angle sensors?

a 255 on an NA seems like overkill but i would suggest the manual fuel pump switch mod

I would check the compression on the engine if you have not done that to this point... If the compression is good, I'd clean and flow the injectors.

There's no point in having a Walbro on an N/A.

Too much fuel pressure can also break your fuel lines. They can stand quite a bit of pressure, but not infinite amounts.

Also.....What did you "check" on these items?

soontoBdrifting

I checked them the way my manual said to (ressistance, opperation, pressure, etc...) the compression is good I checked it four times (each rotor). should I install the stock fuel pump? should I get a pressure regulator? I checked the every thing before I replaced things. I replaced the crank angle sensor because I was getting bad spark(leading) I thouhgt that was the problem. I replaced the throttlebody because the throttle plate would stick fully open(not secondary)
