Engine flooding problem

[lukits01]

My car seems to be having some serious issues here

Was driving to the drags one evening and it suddenly just stopped working

(thank god it didnt happen on the drag strip)

It refused to start even when my friend helped me to jump start it

Towed it to the workshop and they told me they had spark but the injectors seems to be flooding the engine and the only thing they could think of is the ECU is ****ed. The workshop is going to be closed for the weekend so they said they'll test the ECU on monday

Recently before the incident Ive been having problems starting the car

sometimes I had to put some gas into it before it would crank over

and also a few days before I had a bosch 910 installed without a FPR

and exhaust cam gear set to 4Deg retard

So any ideas?

just incase it maters my car is a 1996 R33 Series II Auto

Here's the list of mods I currently have

S-AFCII

Profec B boost controller

Bosch 910 (no FPR)

HKS Exhaust Cam gear

Trust Cat-back

SS high flow cat

Front pipe

Trust V-SPL intercooler

Apexi Air Filter

cheers

keep your foot away from the gas when trying to start it . could help

true that.

i had a similar prob. i manage to avoid it by giving the fuel pump a moment to prime before turning the key the last bit. works every time for me. no pedal.

[lukits01]

well if I dont pump, it wont start

That's not the main problem hehe

now it doesnt start period!

when I try to start the car it backfires regardless whether you pump the gas or not and still doesnt start

[lukits01]

Is it possible that my problem is caused by a dead CAS?

or the FPR not being able to handle the larger fuel pump?

has anyone ever had a problem like this?

I dont think you need a FPR...

Could be stuffed injector stuck open... be carely that you havent filled you cylinder/s with fuel and may have compression locked your motor .... pull the dip stick out and check to see if it smells like fuel??? It s not a common thing - but it does happen, trust me ;-<

Pump the throttle???

1. efi cars are ment to be started with the foot off of the throttle

2. would pumping the throttle actually do anything?? - its not like an old carby that opens up secondary squirters when pumped.

3. when you said you had a pump installed without a FPR, do you mean you removed the standatd/afrermarket FPR on the fuel reguator? if so why??

4. This may not explain why it flooded, but it indicates a few problems.

[lukits01]

well it wont start with or without throttle

and the standard FPR is still there

When I installed the fuel pump my workshop said it might blow the standard FPR because of overpressure. How does that make sense? doesnt the FPR control the pressure?

IMACUL8:

checked out that possibility as well but its not compression lock

but havent checked the injectors though

[blind_elk]

If the engine is "flooded", you need to try and start with the "pedal to the metal" - this is to allow as much air as possible in to help ignite the fuel. DO NOT pump the throttle - that only adds "acceleration" fuel, and worsens the situation.

If the CAS was crook, you would not have spark.

I have been running the standard FPR in my 32 with a Bosch pump, and no problems encountered for nearly 2 years.

Can you hear the injectors working when trying to start the engine?

You are probably going to have to pull the injectors, so arrange to get them cleaned while they are out.

Does anyone know if the CAS from CA18, SR20, RB25Neo, and RB26 are all the same as the R33 RB25DET?

[lukits01]

BACK ON THE ROAD!

turns out the CAS was electronically alive but mechanically dead!

and the little stick at the end of the cam shaft had snapped

oh well got HKS 256 in there now

when the engine is warm the cams are kinna noisy

is this normal?
